RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35
U.S.C. .sctn.119 of U.S. Provisional Application Ser. No.
61/770,823 filed on Feb. 28, 2013, the content of which is relied
upon and incorporated herein by reference in its entirety.
BACKGROUND
[0002] 1. Field of the Disclosure
[0003] The technology of the present disclosure relates to fiber
optic connector adapter modules and, more particularly, to ganged
fiber optic connector adapter module assemblies configured to be
installed data center enclosures.
[0004] 2. Technical Background
[0005] Benefits of optical fiber include extremely wide bandwidth
and low noise operation. Connectors are often used in cable
management systems to provide service connections to rack-mounted
equipment and to provide inter-rack connections. Typical connectors
for mating fiber optics include two connectors that are joined by
an adapter. As one example of a connector, an MPO-style connector
is a multi-fiber connector suitable for high-density backplane and
printed circuit board (PCB) applications for data and telecom
systems. MPO-style connectors generally utilize adapters, which
align the MPO-style connectors with other multi-fiber connectors
for forming a connection therebetween.
[0006] Fiber optic communication systems, such as fiber optic local
area networks (LAN), for example, commonly include fiber optic data
center equipment, such as racks, frames, sub-frames, or enclosures
to provide for connection of a large number of connectorized
optical fibers. In many applications, a large number of ports for
receiving fiber optic connectors are provided in a single
enclosure, which may be arranged according to a desired
configuration. Assembly and/or reconfiguration of the ports in such
data center equipment may be time consuming and costly.
SUMMARY OF THE DETAILED DESCRIPTION
[0007] Embodiments of the present disclosure allow for ganged fiber
optic connector adapter module modules to be installed into a data
center enclosure (e.g., a data center of a local area network
("LAN") or the like) without the use of tools, thereby potentially
reducing installation time and cost. More specifically, a fiber
optic connector adapter module module may include multiple ports
configured to mate with one or more fiber optic connector styles.
The fiber optic connector adapter module modules may convert a
first fiber optic connector style to a second fiber optic connector
style employed in the data center enclosure.
[0008] The multi-port fiber optic connector adapter module module
may be installed into an adapter mount within the data center
enclosure via an adapter mount located within the enclosure.
According to the embodiments described herein, the fiber optic

DETAILED DESCRIPTION
[0041] Reference will now be made in detail to the embodiments,
examples of which are illustrated in the accompanying drawings, in
which some, but not all embodiments are shown. Indeed, the concepts
may be embodied in many different forms and should not be construed
as limiting herein; rather, these embodiments are provided so that
this disclosure will satisfy applicable legal requirements.
Whenever possible, like reference numbers will be used to refer to
like components or parts.
[0042] Embodiments disclosed herein relate to fiber optic connector
adapter module assemblies used in applications that include, but
are not limited to, optical data center applications. More
particularly, embodiments described herein may include one or more
adapter mounts having a plurality of adapter openings for receiving
one or more fiber optic connector adapter modules comprising an
array of fiber optic connector adapters. The adapter mount(s) may
be disposed in a data center enclosure to assist in the connection

because of the fiber optic connector adapter modules may be
installed without the use of tools. Various embodiments of fiber
optic connector assemblies and methods including twist-and-lock and
linear insertion methods are disclosed in detail below.
[0044] Referring now to FIG. 1, a fiber optic connector adapter
module assembly 100 according to one embodiment is illustrated. The
fiber optic connector adapter module assembly 100 generally
includes an adapter mount 101 and a plurality of fiber optic
connector adapter modules 110 that are installed in adapter
openings 102 of the adapter mount 101. The adapter mount 101 may be
disposed in a data center enclosure (not shown), for example, to
provide for optical connection of coupled optical cable assemblies
to a data network (e.g., a local area network ("LAN")). The fiber
optic connector adapter modules 110, each of which includes an
array of fiber optic connector adapters 108, are retained within
the adapter openings 102 of the adapter mount 101. As described in
more detail below, the fiber optic connector adapter modules 110
are installed by positioning the fiber optic connector adapter
module 110 in an insertion region of the adapter opening 102, and
then rotating the fiber optic connector adapter module 110 into an
installation region of the adapter opening 102 where it is
releasably retained by a retention mechanism.
[0045] FIGS. 2A and 2B depict a first side and a second side of an
exemplary fiber optic connector adapter module 110, respectively.
The fiber optic connector adapter module 110, which may be
fabricated from a rigid material, such as molded plastic, includes
an array of fiber optic connector adapters 108 including a
plurality of first ports 111 (FIG. 2A) and a plurality of second
ports 112 (FIG. 2B). The plurality of first ports and the plurality
of second ports may define a plurality of port pairs. Referring
first to FIG. 2A, the first ports 111 have a body 113 that are
shaped to form an opening configured to releasably receive an
MPO-style fiber optic connector 163 (see FIGS. 4 and 5). The first
ports 111 may be configured to receive other fiber optic connector
styles (e.g., SC or LC). Although the illustrated fiber optic
connector adapter module 110 is depicted as having eight first
ports 111, embodiments are not limited thereto.
[0046] Optionally, fiber optic connector adapter modules 110 of the
present disclosure may further include at least one reinforcement
member 120 disposed between adjacent first ports 111. The at least
one reinforcement member 120 may be connected to adjacent first
ports 111 to strengthen the fiber optic connector adapter module
110 by stiffening each first port 111. Accordingly, the at least
one reinforcement members 120 may minimize any deflection, and
therefore the amount of torque experienced by the first ports 111,
under optical cable assembly loads caused by coupled fiber optic
connectors 163.
[0047] In the illustrated embodiment, the at least one
reinforcement member 120 comprises two equally spaced reinforcement
members 120. However, in alternative embodiments, a single,
centrally positioned reinforcement member 120 may be provided.
Further, more than two reinforcement members 120 may be provided.
Although not shown in FIG. 2B, one or more reinforcement members
may be disposed between adjacent second ports 112. Such second port
reinforcement members may be configured as the first port
reinforcement members 120 depicted in FIG. 2A, for example.
[0048] The illustrated fiber optic connector adapter module 110
comprises engagement features 116A-116D that are configured to
contact the adapter mount 101 when the fiber optic connector
adapter module 110 is positioned in the installation region of the
adapter opening 102, as described below. When the fiber optic
connector adapter module 110 is positioned in the installation
region of the adapter opening 102, the engagement features
116A-116D are pressed against the adapter mount.
[0049] In the illustrated embodiment, the fiber optic connector
adapter module 110 has a first engagement feature extending from a
first end 117, and a second engagement feature extending from a
second end 119. The first engagement feature is configured as a
first tab 116A at a first edge 114 and extending from the first end
117 of the fiber optic connector adapter module 110, and a second
tab 116B at a second edge 118 and extending from the first end 117
of the fiber optic connector adapter module 110. The second
engagement feature is configured as a third tab 116C at the first
edge 114 and extending from the second end 119 of the fiber optic
connector adapter module 110, and a fourth tab 116D at the second
edge 118 and extending from the second end 119 of the fiber optic
connector adapter module 110. It should be understood that
embodiments are not limited to number and configuration of the
engagement features 116A-116D depicted in the figures. For example,
in an alternative embodiment, the first engagement feature may be
configured as a single tab extending from the center of the first
end 117 of the fiber optic connector adapter module 110, and the
second engagement feature may be configured as a single tab
extending from the center of the second edge 119 of the fiber optic
connector adapter module 110. Other configurations are also
possible.
[0050] Referring now to FIG. 2B, the fiber optic connector adapters
108 of the illustrated fiber optic connector adapter module 110
includes a plurality of second ports 112 opposing the plurality of
first ports 111 to form a plurality of port pairs. The second ports
112 may face the interior of the data center enclosure when the
fiber optic connector adapter module 110 is installed in the
adapter mount 101, and be configured to receive a fiber optic
connector that is to be coupled to the first fiber optic
connector.
[0051] A ferrule element 180 may be disposed within each first port
111 (and/or second port 112), as shown in FIG. 3. The ferrule
element 180 may take on a variety of configurations, and
embodiments are not limited to the configuration of the ferrule
assemblies depicted herein. As such, the ferrule element 180 is
provided for illustrative purposes only. In the illustrated
embodiment, the ferrule element 180 comprises an optical interface
182 that is defined by an array of lens elements, which are
optically coupled to fiber optic components (not shown), such as
optical fibers or waveguides extending toward a rear opening of the
second port 112 (see FIG. 5). The lens elements may be configured
as refractive lenses, diffractive lenses, gradient-index ("GRIN")
lenses and the like, and be positioned to be optically coupled to
mated lenses of the fiber optic connector inserted into a first
port 111. The optical interface 182 may be positioned at a rear end
of the enclosure defined by the body 113 of the first port 111. As
described below with respect to FIG. 5, the ferrule element 180 may
be configured to translate within the first port 111 and/or the
second port 112.
[0052] The illustrated ferrule element 180 includes mechanical
coupling features that are configured to mate with corresponding
mechanical coupling features of a ferrule element of a fiber optic
connector 163. The exemplary mechanical coupling features of the
illustrated embodiment comprise an alignment pin 184 and an
alignment bore 185. The alignment pin 184 may be inserted into an
alignment bore of the fiber optic connector 163, and the alignment
bore may receive an alignment pin from the fiber optic connector
163.
[0053] Referring now to FIG. 4, an exemplary optical cable assembly
160 having a fiber optic connector 163 configured to be inserted
into one of the first ports 111 of the fiber optic connector
adapter module 110 is depicted. It should be understood that the
fiber optic connector 163 is provided for illustrative purposes
only, and that embodiments are not limited to any type or
configuration of fiber optic connector. The optical cable assembly
160 generally includes a fiber optic cable 161 that is coupled to a
fiber optic connector 163 that is configured as a plug. The fiber
optic cable 161 may include an outer jacket that surrounds and
protects a plurality of optical fibers configured to optical
transmission of optical signals. A strain relief element 162 may
also be provided to protect the plurality of optical fibers from
external forces applied to the optical cable assembly 160. The
fiber optic connector 163 generally comprises a plug body 164 that
defines a ferrule enclosure into which a recessed ferrule element
170 is disposed. Having the ferrule element 170 recessed within the
plug body 164 protects the lens elements of the ferrule element 170
from damage.
[0054] The ferrule element 170 is configured to optically and
mechanically mate with a ferrule element 180 of the fiber optic
connector adapter module 110. In the illustrated, non-limiting
example, the ferrule element 170 of the fiber optic connector 163
includes an optical interface 172 comprising an array of lens
elements (which may be optically coupled to optical elements, such
as optical fibers or waveguides). As described above, the lens
elements may be configured as refractive lenses, diffractive
lenses, GRIN lenses, and the like. The ferrule element 170 further
includes an alignment pin 174 and an alignment bore 175 configured
to mate with the alignment bore 185 and the alignment pin 184 of
the ferrule element 180 within the fiber optic connector adapter
module 110, respectively.
[0055] The exemplary fiber optic connector 163 includes a plug body
opening 167 at an insertion surface 166, which is the surface of
the plug body 164 that is inserted into the first port 111. The
plug body opening 167 is configured to receive the mated ferrule
element 180 the fiber optic connector 163 is coupled to the first
port 111.
[0056] In the illustrated embodiment, the plug body 164 comprises a
first latching arm 165A and a second latching arm 165B that extend
from the insertion surface 166 and are offset from a main portion
of the plug body 164. Although two latching arms are depicted, it
should be understood that more or fewer may be provided in
alternative embodiments. The illustrated first and second latching
arms 165A, 165B include a detent 169 that act as a locking
mechanism that is configured to engage openings 115 of the first
port 111 when the fiber optic connector 163 is inserted into the
first port 111. The first and second latching arms 165A, 165B may
include a release tab 168 at an end that is distal from the
insertion surface 166. The first and second latching arms 165A,
165B are compliant in a direction transverse to the insertion
direction upon application of force applied to the release tabs
168.
[0057] FIG. 5 depicts a cross-sectional view of the exemplary fiber
optic connector 163 inserted into a first port 111 of a fiber optic
connector adapter module 110. Optical fibers are not shown in FIG.
5 for clarity and ease of illustration. The ferrule element 180
within the first port 111 ("port ferrule element") in the
illustrated embodiment is biased from an enclosure defined by the
second port 112 toward an enclosure defined by the first port 111
by a bias member 187. The bias member 187 may be configured as a
spring, for example. Accordingly, the port ferrule element 180 may
translate within the fiber optic connector adapter module 110 upon
insertion and removal of the fiber optic connector 163. The bias
member 187 is maintained within the enclosure defined by the second
port 112 by a clip element 190 in the illustrated embodiment. Other
configurations are also possible.
[0058] The ferrule element 170 within the enclosure defined by the
fiber optic connector 163 ("plug ferrule element") mates with the
port ferrule element 180 when the fiber optic connector 163 is
inserted into the first port 111 in a direction indicated by arrow
A. As shown in FIG. 5, the plug ferrule element 170 and the port
ferrule element 180 may each include fiber bores 178, 188 in which
optical fibers (or waveguides and/or other optical components) may
be disposed. The optical fibers (not shown) may terminate at the
respective optical interface 172, 182, or terminate at some other
optical components within the plug ferrule element 170 and the port
ferrule element 180 (e.g., GRIN lenses or waveguides).
[0059] The fiber optic connector 163 may be inserted into the first
port 111 until the detents 169 of the first and second latching
arms 165A, 165B are positioned in the openings of the body 113 of
the first port 111. The alignment pin 174 of the plug ferrule
element 170 is inserted into the alignment bore 185 of the port
ferrule element 180, and the alignment pin 184 of the port ferrule
element 180 is inserted into the alignment bore 175 of the plug
ferrule element 170. In this manner, the alignment pins 174, 184
and the alignment bores 175, 185 provide fine alignment of the lens
elements of the two coupled optical interfaces 172, 182. The plug
ferrule element 170 may push the port ferrule element 180 along
direction A such that the bias member 187 applies a force on the
plug ferrule element 170 to maintain optical coupling between the
optical interfaces 172, 182.
[0060] It should be understood that other connectors and coupling
configurations may be provided, and that the embodiments depicted
in at least FIGS. 4 and 5 are used merely as examples.
[0061] Referring now to FIG. 6A, a second surface 103 (i.e., rear
surface that faces the internal components of the data center
enclosure) of an adapter mount 101 according to one embodiment is
illustrated. The adapter mount 101, which may be fabricated from
any suitably rigid material, such as metal, includes a plurality of
adapter openings 102 into which a plurality of fiber optic
connector adapter modules 110 may be inserted. The number of
adapter openings 102 may depend on the type and/or area of the data
center enclosure the adapter mount 101 is to be installed. The
illustrated adapter mount 101 includes 13 adapter openings 102;
however, more or fewer adapter openings 102 may be included. The
adapter mount 101 may be configured to be installed in a data
center enclosure by any number of methods. The attachment method
may depend on the end application.
[0062] Each adapter opening 102 may have at least one retention
mechanism associated therewith. The retention mechanism is
configured to retain the fiber optic connector adapter module 110
in the installed position within the adapter opening 102. In the
illustrated embodiment, the retention mechanism is configured as
two spring clips 130. One spring clip 130 is located proximate a
first, top end of the adapter opening 102, while another spring
clip is located proximate a second, bottom end of the adapter
opening 102. The spring clips 130 of the illustrated embodiment are
located on opposite sides of the adapter opening 102. The spring
clips 130 may be fabricated from metal, for example, and be coupled
to the second surface 103 of the adapter mount 101 by any
appropriate means (e.g., welding, adhesive, solder, fasteners, and
the like). It should be understood that the spring clips 130 may be
made of materials other than metals. The retention mechanism(s) may
take on other configurations, as described in more detail
below.
[0063] FIG. 6B is a close-up view of a single adapter opening 102.
As stated above, the adapter opening 102 comprises an insertion
region 140 and an installation region 141. The insertion region 140
is larger than the installation region 141, and is dimensioned to
accept the fiber optic connector adapter module 110. In other
words, at least a portion of the fiber optic connector adapter
module 110 may pass through the adapter opening 102 at the
insertion region 140. The insertion and installation process
according to one embodiment is described below with reference to
FIGS. 7A-8. The insertion region 140 is angled with respect to the
installation region 141, which is aligned with the y-axis in FIG.
6B. Accordingly, the fiber optic connector adapter module 110 is
inserted into the insertion region 140 at an angle .theta. with
respect to the y-axis and the installation region 141.
[0064] The shape of the adapter opening 102 may depend on the shape
and configuration of fiber optic connector adapter module 110. The
insertion region 140 should be larger than the installation region
141 such that the fiber optic connector adapter module 110 may be
inserted into the insertion region 140 and then rotated such that
it contacts a portion of the adapter mount 101 and is restricted
from movement in three directions due to the shape of the
installation region and/or any retaining mechanisms (e.g., spring
clips 130). In the illustrated embodiment, the insertion region 140
of the opening is defined by a first angled edge 107A and a second
angled edge 107B. The first and second angled edges 107A, 107B are
angled by an angle .theta. with respect to the y-axis and are
parallel with respect to one another. The first angled edge 107A
transitions into a first straight edge 108A that is opposite from
the second angled edge 107B, and defines a portion of the
installation region 141. The second angled edge 107A transitions
into a second straight edge 108B that is opposite from the first
angled edge 107A, and defines a portion of the installation region
141. The first and second angled edges 107A, 107B are offset with
respect to one another by a distance w.sub.1 that defines a width
of the insertion region 140. The distance w.sub.1 should be greater
than a width of the fiber optic connector adapter module 110 such
that the fiber optic connector adapter module 110 may pass through
the adapter opening 102 at the insertion region 140. The first and
second straight edges 108A, 108B are offset with respect to one
another by a distance w.sub.2 that is smaller than a width of the
fiber optic connector adapter module 110.
[0065] Positioned at a first end 109A of the exemplary adapter
opening 102 (i.e., a top end) are a first notch 106A and a second
notch 106B, and positioned at a second end 109B of the adapter
opening 102 (i.e., a bottom end) are a third notch 106C and a
fourth notch 106D. The first through fourth notches 106A-106D are
dimensioned and positioned to receive the first through fourth tabs
116A-116D when the fiber optic connector adapter module 110 is
positioned in the insertion region 140. In the illustrated
embodiment, the second and third notches 106B, 106C are angled by
angle .theta. with respect to the y-axis to accommodate the second
and third tabs 116B, 116C, respectively. The notches 106A-106D
define contact areas 143A-143D that are configured to contact the
first through fourth tabs 116A-116D when the fiber optic connector
adapter module 110 is positioned in the installation region 141 of
the adapter opening 102. Although the first and fourth notches
106A, 106D are larger than the second and third notches 106B, 106C,
embodiments are not limited thereto. Further, it should be
understood that alternative embodiments may include notches that
are positioned in locations other than those depicted in FIG. 6B,
and that the placement, configuration and dimensions of the notches
may depend on the configuration of the fiber optic connector
adapter module 110 intended to be mounted in the adapter mount
101.
[0066] Installation of a fiber optic connector adapter module 110
into an adapter opening 102 of an adapter mount 101 will now be
described with reference to FIGS. 7A-7C. First, referring to FIG.
7A, the fiber optic connector adapter module 110 is turned by the
angle .theta. with respect to vertical (or another reference
orientation, depending on how the adapter mount 101 is installed in
the data center enclosure) such that the first, second, third, and
fourth tabs 116A-116D defining the engagement features are aligned
with the first, second, third and fourth notches 106A-106D of the
adapter opening 102, respectively. Referring to FIG. 7B, the fiber
optic connector adapter module 110 is moved into the insertion
region 140 (see FIG. 6B) such that the tabs 116A-116D are disposed
in the respective notches 106A-106D. The fiber optic connector
adapter module 110 is then rotated as indicated by arrow B such
that it is vertical (or aligned in another reference orientation,
depending on how the adapter mount 101 is installed in the data
center enclosure), aligned with the y-axis as shown in FIG. 6, and
positioned in the installation region 141 of the adapter opening
102 (FIG. 7C).
[0067] Rotation of the fiber optic connector adapter module 110
from the insertion region 140 to the installation region 141 causes
the first tab to contact the first contact area 143A of the adapter
mount 101, the second tab to contact the second contact area 143B,
the third tab to contact the third contact area 143C, and the
fourth tab to contact the fourth contact area 143D. Additionally,
in the illustrated embodiment, a portion of the first edge 114 of
the fiber optic connector adapter module 110 contacts the second
surface 103 of the adapter mount 101 proximate to the first
straight edge of the adapter opening 102, and a portion of the
second edge 118 of the fiber optic connector adapter module 110
contacts the second surface 103 of the adapter mount 101 proximate
to the second straight edge of the adapter opening 102.
[0068] The areas of the fiber optic connector adapter module 110
that contact the adapter mount 101 as described above may be
pressed against the second surface 103 by one or more retention
mechanisms. Referring now to FIG. 8, a close-up, perspective view
of the second surface 103 of the adapter mount 101 and a top end of
an installed fiber optic connector adapter module 110 is
illustrated. The second surface 103 of the adapter mount 101
include spring clips as shown in FIG. 6A. The spring clip 130 may
include an arm 132 that is offset from the second surface 103 of
the adapter mount 101 to receive a tab (e.g., first tab 116A and
fourth tab 116D) of the fiber optic connector adapter module 110.
In some embodiments, the end 134 of the arm 132 may be outwardly
flared to assist in guiding the tab into the gap between the arm
132 and the second surface 103 of the adapter mount 101. The spring
clips 130 apply a force to the fiber optic connector adapter module
110 to releasably retain it in the installation region 141 of the
adapter opening 102. Referring once again to FIG. 7C, the fiber
optic connector adapter module 110 may be rotated in a direction
opposite from the direction indicated by arrow B (e.g., a clockwise
direction) to remove the tabs (e.g., first and fourth tabs 116A,
116D) from the spring clips 130 such that the fiber optic connector
adapter module 110 is in the insertion region 140 where it may be
pulled out of the adapter opening 102.
[0069] Referring now to FIGS. 9A and 9B, an alternative fiber optic
connector adapter module 210 is illustrated. FIG. 9A is a side
perspective view of the fiber optic connector adapter module 210,
while FIG. 9B provides a side view. Similar to the fiber optic
connector adapter module 110 depicted in FIGS. 1, 2A, 2B, 3, 7A-7C,
and 8, the fiber optic connector adapter module 210 depicted in
FIGS. 9A and 9B include an array of fiber optic connector adapters
208 including an array of first ports 211 and an array of
corresponding second ports 212. It should be understood that the
first and second ports 211, 212 may take on configurations other
than those depicted. The fiber optic connector adapter module 210
further includes a first engagement feature 215A and a second
engagement feature 215B extending a length of the fiber optic
connector adapter module 210 that define first and second tabs
216A, 216B and third and fourth tabs 216C, 216D, respectively, as
described above. Alternatively, more or fewer notches may be
provided.
[0070] The illustrated fiber optic connector adapter module 210
includes an additional engagement plate 250 that is offset from the
first and second engagement features 215A, 215B. Accordingly, a gap
g is present between the engagement plate 250 and the first
engagement feature 215A, and between the engagement plate 250 and
the second engagement feature 215B. The engagement plate 250
contacts a first surface 104 of the adapter mount 101, while the
first and second engagement features 215A, 215B contact the second
surface 103 of the adapter mount 101.
[0071] FIGS. 10A-10B depict the installation of the fiber optic
connector adapter module 210 into the adapter opening 102 of the
adapter mount 101. The adapter mount 101 is the same adapter mount
101 that is depicted in FIGS. 7A-7C. First, referring to FIG. 10A,
the fiber optic connector adapter module 210 is turned by the angle
.theta. with respect to vertical (or another reference orientation,
depending on how the adapter mount 101 is installed in the data
center enclosure) such that the first, second, third, and fourth
tabs 116A-116D (not visible in FIGS. 10A-10C) are aligned with the
first, second, third and fourth notches 106A-106D of the adapter
opening 102, respectively. Referring to FIG. 10B, the fiber optic
connector adapter module 110 is moved into the insertion region 140
such that the tabs 116A-116D are disposed in the respective notches
106A-106D. The fiber optic connector adapter module 110 is then
rotated as indicated by arrow B such that it is vertical (or
aligned in another reference orientation, depending on how the
adapter mount 101 is installed in the data center enclosure),
aligned with the y-axis as shown in FIG. 6, and positioned in the
installation region 141 of the adapter opening 102 (FIG. 10C). The
engagement plate 250 contacts the first surface 104 of the adapter
mount 101, while the first through fourth tabs 216A-216D contact
the second surface 103 of the adapter mount 101 (e.g., as described
above with respect to FIGS. 7B, 7C and 8). Accordingly, portions of
the adapter mount 101 are disposed within the gaps g defined by the
engagement plate 250 and the first and second engagement features
215A, 215B.
[0072] In some embodiments, the fiber optic connector adapter
module 210 may be retained in the installation region 141 of the
adapter opening 102 by an interference fit of the adapter mount 101
within the gap g between the engagement plate 250 and the first and
second engagement features 215A, 215B. Therefore, separate
retention mechanisms (e.g., the spring clips 130 described above)
may not be needed in such embodiments. However, one or more
retention mechanisms may be utilized in embodiments. FIG. 11
depicts the second surface 103 of a populated adapter mount 101
defining a fiber optic connector adapter module assembly 200. In
the illustrated embodiment, two spring clips 130 are used to retain
each fiber optic connector adapter module 210, such as described
above with reference to FIG. 8. FIG. 12 depicts the first surface
104 of the populated adapter mount 101 depicted in FIG. 11.
[0073] In some embodiments, the first and second engagement
features 215A, 215B and/or the engagement plate 250 may include
tapers or ribs to insure a tight interference fit with the adapter
mount 101, as well as to accommodate different adapter mount
thicknesses without requiring different fiber optic connector
adapter module designs. FIGS. 13A and 13B depict a fiber optic
connector adapter module 210 having two rib features 217 on each of
the first and second engagement features 215A, 215B to insure a
tight interference fit with the adapter mount 101.
[0074] Retention mechanisms other than the spring clips 130
described above may be utilized in embodiments. FIGS. 14A and 14B
depict a fiber optic connector adapter module assembly 300 that
utilizes a locking peg 330 as the retention mechanism. FIG. 14A is
a front perspective view of a populated adapter mount 301, while
FIG. 14B is a close-up view of a top portion of a fiber optic
connector adapter module 310 and a locking peg 330. The illustrated
fiber optic connector adapter module assembly 300 generally
comprises an adapter mount 301, which may be configured as
described above, and a plurality of fiber optic connector adapter
modules 310 having an engagement plate 350 as describe above with
reference to FIGS. 9A-12.
[0075] Referring briefly to FIG. 15A, the adapter mount 301
includes a lock opening 335 located above each adapter opening 102
configured to receive a locking peg 330. Referring once again to
FIGS. 14A and 14B, each fiber optic connector adapter module 310
includes an opening 318 to accept the locking peg 330. Each fiber
optic connector adapter module 310 includes an array of fiber optic
connector adapters 308 defined by first and second ports 311, 312.
In the illustrated embodiment, the opening 318 is configured as a
notch in the top end of the engagement plate 350. When installed,
the locking peg 330 prevents rotation of the fiber optic connector
adapter module 310 from the installation region 141 of the adapter
opening 102. Although the opening 318 is illustrated as a notch in
the present example, it may also be configured as a through-hole in
alternative embodiments.
[0076] As shown in FIG. 14B, the locking peg may have a base 332
that matches the diameter of the opening 318 in the engagement
plate 350 to prevent rotation of the fiber optic connector adapter
module 310. The illustrated embodiment includes a trunk portion 334
and an upper portion 336 that is configured to be handled by a
user. As an example and not a limitation, the upper portion 336 may
include a texture, such as a knurl and the like, to assist the user
in operating the locking peg 330. The locking peg 330 may be
retained in the lock opening 335 by an interference fit, a snap
fit, screw-fit (e.g., the locking peg 330 and the lock opening may
be threaded), etc.
[0077] Installation of a fiber optic connector adapter module 310
into the adapter opening 102 of an adapter mount 301 using a
locking peg 330 will now be described with reference to FIGS.
15A-15D. First, referring to FIG. 15A, the fiber optic connector
adapter module 310 is turned by the angle .theta. with respect to
vertical (or another reference orientation, depending on how the
adapter mount 301 is installed in the data center enclosure) such
that the first, second, third, and fourth tabs (not visible in
FIGS. 15A-15D) are aligned with the first, second, third and fourth
notches 106A-106D of the adapter opening 102, respectively.
Referring to FIG. 15B, the fiber optic connector adapter module 310
is moved into the insertion region 140 such that the tabs 116A-116D
are disposed in the respective notches 106A-106D. The fiber optic
connector adapter module 310 is then rotated as indicated by arrow
B such that it is vertical (or aligned in another reference
orientation, depending on how the adapter mount 301 is installed in
the data center enclosure), aligned with the y-axis as shown in
FIG. 6, and positioned in the installation region 141 of the
adapter opening 102 (FIG. 15C). When the fiber optic connector
adapter module 310 is positioned in the installation region 141,
the opening 318 (the notch in the present example) is vertically
aligned with the lock opening 335. The engagement plate 350
contacts the first surface 104 of the adapter mount 301, while the
first through fourth tabs (not shown) contact the second surface
103 of the adapter mount 101 (e.g., as described above with respect
to FIGS. 7B, 7C, 8 and 10A-10C). Once the fiber optic connector
adapter module 310 is positioned in the installation region 141,
the locking peg 330 may be inserted into the lock opening 335 such
that it is also disposed in the opening 318 of the engagement plate
350 as shown in FIG. 15D, thereby preventing rotation of the fiber
optic connector adapter module 310 in the adapter opening 102 of
the adapter mount 301.
[0078] Referring now to FIGS. 16A, 16B, 17 and 18A-18C a fiber
optic connector adapter module 410 and an adapter mount 401 of an
exemplary fiber optic connector adapter module assembly 400 are
illustrated. Generally the illustrated fiber optic connector

plate depicted in FIGS. 9A and 9B.
[0082] Referring now to FIG. 17, an exemplary adapter mount 401
comprising a plurality of adapter openings configured to receive a
plurality of fiber optic connector adapter modules 410 is depicted.
Each adapter opening 402 has a first edge 405A defined by a
plurality of first alternating tabs 443A and notches 406A and an
opposing second edge 405B defined by a plurality of second
alternating tabs 443B and notches 406B. Each adapter opening 402
further includes a top edge 407A and an opposing bottom edge 407B.
Any number of adapter openings 402 may be provided in the adapter
mount 401.
[0083] Each adapter opening 402 defines an insertion region 440
that extends from the top edge 407A to the bottom edge 407B and
between the first and second edges 405A, 405B. Each adapter opening
402 also defines an installation region 441 that overlaps, and is
smaller than, the insertion region 440. The installation region 441
extends from the dashed line 442 to the bottom edge 407B and
between the first and second edges 405A, 405B. The first and second
notches 406A, 406B are dimensioned and positioned to accept the
first and second engagement tabs 416A, 416B. Accordingly, the shape
of the first and second notches 406A, 406B correspond to the shape
of the first and second engagement tabs 416A, 416B. The first and
second notches 406A, 406B may be slightly larger in area than the
first and second engagement tabs 416A, 416B so that they may
receive the first and second engagement tabs 416A, 416B.
[0084] The first and second tabs 443A, 443B of the adapter opening
402 are positioned between the first and second notches 406A, 406B
and are configured to contact the first and second engagement tabs
416A, 416B when the fiber optic connector adapter module 410 is
positioned in the installation region 441 of the adapter opening
402. It should be understood that the first and second tabs 443A,
443B may take on shapes other than the rectangular shape depicted
in FIG. 17.
