PITCH GREATER THAN THE DIAMETER OF THE FIBER
Abstract
An optical fiber arranging tool has a base, a top surface, and a
recessed channel extending along the base and has a plurality of
ribs disposed within the recessed channel. The plurality of ribs
have a pitch of 250 microns creating a plurality of grooves for
receiving the optical fibers. The tool may also have a latch
extending from the top surface of the base on one side of the
recessed channel and across the recessed channel to a second side
of the recessed channel, there being a slot between the top surface
of the base and an underside of the latch and in communication with
the recessed channel. A method for aligning the optical fibers at a
pitch that is larger than the outer diameter of the optical fibers
includes sliding individual optical fibers one by one into slot and
the recessed channel, moving an object along the optical fibers in
the recessed channel, passing the individual optical fibers through
a respective one of a plurality of grooves created by ribs within
the recessed channel and maintaining the individual optical fibers
at a distance of 0.250 mm at an end of the recessed channel.

Description
BACKGROUND OF THE INVENTION
[0001] This application claims priority to U.S. Provisional Patent
Application Ser. No. 62/723,578, filed on Aug. 28, 2018, and is a
continuation application of U.S. Pat. No. 11,231,553 issued on Jan.
25, 2022, which is a 371 application of PCT/US19/48378 filed on
Aug. 28, 2018, the contents of all of which are incorporated by
reference.
FIELD OF THE INVENTION
[0002] The areas that are used for placing and terminating optical
fibers are getting more and more limited, while the demand for
having optical fibers is getting larger. As a result, changes are
needed to allow more optical fibers to be present. One possibility
is to use more space for the optical fibers, but there is only so
much space available. Another is to put more optical fibers in the
same amount of space (i.e., conduits). Putting more optical fibers
in the same space means that the cables that contain the optical
fibers and the optical fibers themselves need to be smaller. Newer,
smaller optical fibers (e.g., new 200-micron or smaller coated
optical fibers) are now available. Using this new optical fiber
allows for a large reduction in the size of the cable and thus a
higher density of cables in the same space. However, the installed
equipment is all based on the 250 micron optical fibers, so the
equipment is designed for the 250 micron optical fibers that have a
250 micron pitch. Thus, it is difficult to use the smaller, newer
optical fibers with the older equipment without some changes to the
way that the equipment is used. The new optical fibers (200 micron)
have to be arranged and presented on a 250 micron pitch. In this
way, the new optical fibers can be backward compatible--used with
the fiber optic ferrules and connectors that use the 250 micron
optical fibers. To arrange these smaller optical fibers to be used
with the older equipment, the optical fibers need to be held
together with a 250 micron pitch.
[0003] A tool and a method have been invented that allows for the
smaller diameter optical fibers to be held together in their proper
order for termination.
SUMMARY OF THE INVENTION
[0004] The present invention is directed to an optical fiber
arranging tool that includes a base having a front end, a rear end,
a top surface, a bottom surface, and a recessed channel extending
along the base from the rear end to the front end of the base, the
recessed channel having a portion of the top surface on either side
thereof, a latch extending from the top surface of the base on one
side of the recessed channel and across the recessed channel to a
second side of the recessed channel, there being a slot between the
top surface of the base and an underside of the latch and in
communication with the channel, and a plurality of ribs disposed
within the recessed channel having a pitch of 250 microns creating
a plurality of grooves at the front end.
[0005] In some embodiments, the recessed channel has a bottom
surface and two side walls, the bottom surface being at least half
a fiber diameter below the top surface of the base.
[0006] In some embodiments, the recessed channel has a first width
at the rear end and a second width at the front end, the first
width being smaller than the second width.
[0007] In some embodiments, the the recessed channel has central
axis at the rear end, one of the side walls being parallel to the
central axis along the length of the recessed channel.
[0008] In another aspect, the invention is directed to a method for
arranging optical fibers at a pitch greater than a diameter of the
optical fibers in tool having a base with a top surface and a
recessed channel in the base with a portion of the top surface on
either side of the recessed channel, the method that includes
sliding individual optical fibers one by one into a slot and into
the recessed channel, moving an object along the optical fibers in
the recessed channel (and the top surface) from the slot towards an
end of the base, passing the individual optical fibers through a
respective one of a plurality of grooves created by ribs within the
recessed channel, and maintaining the individual optical fibers at
a distance of 0.250 mm at an end of the recessed channel.
[0009] In some embodiments, the method also includes applying an
adhesive to the optical fibers inside the recessed channel,
inserting the arranged optical fibers into an MT fiber optic
ferrule, and terminating the MT fiber optic ferrule.
[0010] According to another aspect, the present invention is
directed to an optical fiber arranging tool that includes a base
having a recessed channel extending along the base from adjacent a
rear end to a front end of the base, a stacker associated with the
base at the front end, there being a slot in the stacker to receive
optical fibers to be arranged, the slot having a width that is less
than twice the diameter of the optical fibers, and a plurality of
grooves disposed within the recessed channel having a pitch of 250
microns at the front end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0026] Reference will now be made in detail to the present
preferred embodiment(s) of the invention, examples of which are
illustrated in the accompanying drawings. Whenever possible, the
same reference numerals will be used throughout the drawings to
refer to the same or like parts.
[0027] One embodiment of an optical fiber arranging tool 100 is
illustrated in FIG. 1. The optical fiber arranging tool 100 has a
base 102 that extends between a front end 104 and a rear end 106.
The base 102 is illustrated as having a rectangular shape, with the
front end 104 and the rear end 106 as being flat surfaces that are
parallel to one another. Additionally, the base 102 has two side
surfaces 108 and 110, which are parallel to one another and
generally perpendicular to the front and rear ends 104, 106.
However, the base 102 may have many different configurations,
shapes, and surfaces and still fall within the scope of this
application. For example, the front and rear ends 104, 106 may not
be perpendicular to the side surfaces 108 and 110. Additionally,
front and rear ends 104, 106 and the side surfaces 108 and 110 may
not be planar as illustrated. As noted below, the base 102 provides
the structure for the recessed channel 120.
[0028] The base 102 also includes a top surface 112 and a bottom
surface 114. The top surface 112 may or may not be parallel to the
bottom surface 114. Preferably, the top surface 112 is smooth and
has a recessed channel 120 extending from the top surface 112 into
the base 102 in the direction of the bottom surface 114. The
recessed channel 120 preferably divides the top surface into two
portions, 112a and 112b. While the two portions 112a and 112b are
illustrated as being the same (width, length, configuration, etc.)
on both sides of the recessed channel 120, they need not be
identical. The recessed channel 120 has a longitudinal axis A that
passes therethrough. Additionally, while it is preferable that the
longitudinal axis A is perpendicular to the front end 104 and the
rear end 106 and parallel to the sides 108 and 110, again, it need
not be. As noted above, the front end 104 and the rear end 106 and
the sides 108, 110 may have different configurations preventing the
longitudinal axis A from being perpendicular to these
structures.
[0029] The recessed channel 120 preferably extends between the
front end 104 and the rear end 106 and has a bottom surface 122, a
first side wall 124 and a second side wall 126. While the recessed
channel 120 is illustrated as extending the entirety of the length
of the base 102, it could extend only along a portion of the length
between the front end 104 and the rear end 106. For example, the
recessed channel 120 may not start at the front end 104, but could
start between the front end 104 and the rear end 106. Similarly,
the recessed channel may end before reaching the rear end 106.
[0030] The recessed channel 120 has a width W at the rear end 106
(or wherever it were to start along the length of the base 102)
that preferably corresponds to the width of the number of optical
fibers 200 that are to be oriented. Typically, the number of fibers
correspond to the number of openings in a fiber optic ferrule--2,
4, 8, or 12. However other numbers of optical fibers could be
accommodated as well. Thus, if there were 12 optical fibers to be
arranged and the optical fibers had a diameter of 200 microns, then
the recessed channel 120 would have a width of 2.4 mm. At the other
end, the recessed channel 120 would have a width of 3.0 mm
(12.times.0.250 mm) to match to the existing openings in the fiber
optic ferrules. Preferably there would one tool for each of the
different numbers of optical fibers to be arranged. Alternatively,
customized widths of the recessed channel 120 may be provided
depending on the number of optical fibers that need to be
terminated.
[0031] The optical fiber arranging tool 100 also has a latch 130
that extends from one side of the recessed channel 120 to the other
side. Thus, the latch 130 is attached to the base 102 on the first
portion 112a of the top surface 112 and extends across the recessed
channel 120 to the second portion 112b of the top surface 112. The
latch 130 could be made integrally with the base 102 or it could be
added later and secured to the base in any appropriate manner.
[0032] As best seen in FIG. 2, the latch 130 extends from the top
surface portion 112a across the recessed channel 120 and above the
top surface portion 112b at a terminal point 132. The latch 130 has
an under surface 134 to define a slot 136 between the latch 130 and
the recessed channel 120 as well as the top surface portion 112b.
The latch 130 has a chamfered portion 138 that extends from the
terminal point 132 to the underside 134. The chamfered portion 138
creates a narrowed portion 140 of the slot 136 at the end of the
underside 134 and above the top surface portion 112b. The narrowed
portion 140 of the slot 136 is preferably less than the diameter of
the optical fibers 200 that are inserted, i.e., less than 200
microns. The latch 130 is flexible to allow it to be flexed upward
away from the top surface portion 112b when the optical fibers 200
are inserted into the recess channel 120. This spacing of the
narrowed portion 140 prevents the optical fibers 200 from
accidentally slipping out from underneath the latch 130.
Additionally, the slot 136 between the underside 134 and the
recessed channel 120 is less than the diameter of two optical
fibers 200 (less than 400 mm) to prevent the optical fibers 200
from sliding past one another in the recessed channel 120. This
will maintain the order of the optical fibers 200 within the
channel, for example, by their colors: blue, orange, green, brown,
slate, white, red, black, yellow, violet, rose, and aqua. Thus,
this area around the latch 130 can be referred to as the organizing
area 142. See FIG. 3.
[0033] In a portion of the recessed channel 120 between the latch
130 and the front end 104, there is a positioning area 144 for the
optical fibers 200 that have been inserted under the latch 130. The
optical fibers 200 are loose and have the ribbon matrix/adhesive
removed. One could place the optical fibers 200 into the
positioning area 144 before sliding them into the space 136, or
after, depending on the user's preference for inserting the optical
fibers 200. The positioning area 144 has a width that is preferably
the same as the width of the recessed channel 120 at the latch
130--the organizing area 142.
[0034] With the optical fibers 200 being in the correct order in
the organizing area 142, the user can press on the optical fibers
200 in the positioning area 144 with a finger or other object (and
on the top surface portions 112a/112b) and move the finger or
object toward the front end 104. This pressure will move the
optical fibers 200 along their length into the correct order along
the recessed channel 120 in the positioning area 144. Moving toward
the front end 104 of the base 102 and in the separating area 146,
the recessed channel 120 begins widening to allow for the proper
spacing of the optical fibers 200. See FIG. 4. The recessed channel
has the first side wall 124 and the second side wall 126 to retain
the optical fibers 200 therein. Preferably the recessed channel 120
has a depth (and the first and second side walls 124,126 have a
height) of at least one half of the diameter of the optical fibers
200 (deeper than a fraction of the optical fiber's diameter), i.e.,
at least 100 microns. Preferably, the depth would not be larger
than the diameter of the optical fibers, although there is no real
downside to having it deeper.
[0035] In the recessed channel 102 towards the front end 104, there
are a plurality of ribs 150 that are disposed on the bottom surface
122 and between the first side wall 124 and the second side wall
126. See FIGS. 5 and 6. The plurality of ribs 150 could be
integrally formed with the base 102 or can be attached to the
bottom surface 122 later. Preferably the plurality of ribs 150 have
the same height as the first side wall 124 and the second side wall
126. It is possible that some of the plurality of ribs 150 have a
different height than others of the plurality of ribs 150. The
plurality of ribs 150 preferably terminate at the front end 104.
However, it is possible that they terminate prior to the front end
104. The plurality of ribs 150 have a width WR that allows for the
optical fibers 200 to have a pitch of 250 microns on centers. That
is, the centers of the optical fibers 200 are spaced at 250
microns. See, e.g., FIGS. 7A-C
[0036] The plurality of ribs 150 have a central rib 150a that is
longer than all of the other of the plurality of ribs 150. On each
side of the central rib 150a is a respective second plurality of
ribs 152a/152b with each of the ribs in each of the second
plurality of ribs 152a/152b getting shorter moving away from the
central rib 150a. Thus, the ribs next to the first side wall 124
and the second side wall 126 are the shortest of the ribs. While it
is preferable that the length of the ribs in each of respective
second plurality of ribs 152a/152b are the same (e.g., the third
rib on either side of the central rib 150a), it is possible for
them to have other lengths than the corresponding rib on the
opposite side of the central rib 150a.
[0037] As the user pushes a finger/object along the optical fibers
200 toward the front end, the central rib 150a will divide the
optical fibers 200 into two groups of the same size. For those
cases where 12 optical fibers are used, the central rib 150a will
divide the optical fibers 200 into two groups of 6 optical fibers.
If there are only 8 optical fibers and the base is configured to
receive 8 optical fibers, then the central rib would divide the
optical fibers into two sets of 4 optical fibers.
[0038] For discussion purposes, the number of optical fibers 200
will be assumed to be 12. With 12 optical fibers, there would
therefore need to be 11 ribs--one central rib and then five ribs on
either side thereof. See FIG. 6. After the optical fibers are
divided into two groups of six fibers, the two optical fibers on
either side of the central rib 150 (fibers 6 and 7) are then
separated from the two pluralities of optical fibers. Moving
farther toward the front end 104, then the next two fibers (5 and
8) are separated. This process continues (4 and 9; 3 and 10; 2 and
11; and 1 and 12) until all 12 optical fibers 200 are separated
from one another. See FIG. 4. Since the plurality of ribs 150 have
arranged such that the core of the optical fibers 200 are on 250
micron pitch, the optical fibers 200 can be glued on the base 102
to retain the optical fibers on the 250 micron pitch and inserted
into the appropriate receptacle (fiber optic connector, fiber optic
ferrule, plug, etc.). The receptacle can then be terminated as with
the prior devices and spacing.
[0039] The plurality of ribs 150 may take a variety of shapes,
provided that they cause the optical fibers to have a 250 micron
pitch. As illustrated in FIG. 7A, the plurality of ribs 150 may
have a rectangular cross section. In FIG. 7B, the plurality of ribs
250 are illustrated as being v-grooves and FIG. 7C shows the
plurality of ribs 350 as being of a frustoconical shape. Other
cross-section shapes of the ribs include shapes that create
U-shaped grooves or U-grooves between the plurality of ribs. It
should be noted that the plurality of ribs need allow the optical
fibers 200 to have enough exposed area to allow the adhesive used
to form a sufficient bond to the optical fibers 200 to retain them
at the correct pitch without coming apart or breaking.
[0040] As noted above, the recessed channel 120 has the organizing
area 142 and the positioning area 144 with two parallel side walls
(first side wall 124 and the second side wall 126) and then the
side walls diverge from one another at the separating area 146. As
illustrated in FIGS. 8 and 9, another embodiment of a second
optical fiber arranging tool 100' illustrates that it is possible
for one of the side walls, the first side wall 124', to be parallel
to longitudinal axis A' along the entire length of the base 102'.
It should be noted that the second side wall 126' could
alternatively be the one that is parallel to the longitudinal axis
A'. In this embodiment, the recessed channel 120' is sized for only
eight optical fibers 200.
[0041] Another change in optical fiber arranging tool 100' is that
the plurality of ribs 150' are increasing turned relative to the
longitudinal axis A' (i.e., non-parallel to one another). Starting
at the first rib by first side wall 124' (at the bottom of the
recessed channel 120' in FIG. 9), the ribs are increasing turned in
a counter-clockwise rotation--that is there is smaller distance
between adjacent ribs at the rear end of the tool than at the front
end. This turning of the ribs, and therefore the plurality of
optical fibers, allows for the change in width (from 2.4 mm to 3.0
mm) of the 12 optical fibers as the spacing is changed from 200
microns to 250 microns.
[0042] The recessed portion 120 (and 120') has been illustrated in
the prior figures as being flat from one end of the base 102 to the
other. However, it is possible that there be a step 160 in the
recessed portion between the latch 130 and the plurality of ribs.
See FIG. 10. Alternatively the recessed portion 120 (and 120') may
also have a ramp configuration 162 as illustrated in FIG. 11.
[0043] Another embodiment of an optical fiber arranging tool 400 is
illustrated in FIGS. 12 and 13. The optical fiber arranging tool
400 has a base 402 that extends between the front end 404 and a
rear end 406. The base 402 as a recessed channel 420 extending
between the front end 404 and the rear end 406 and between the
first side wall 424 and the second side wall 426. At the front end
404 is a stacker 430 that receives in a slot 436 the optical fibers
(not shown). The optical fibers would be inserted into the slot 436
in the correct order. As illustrated in FIG. 12, stacker 430 can be
rotated up so that the optical fibers can be inserted into the slot
436. Preferably, a small portion of the length of the optical
fibers would extend to the right of the stacker 430, while a larger
portion would extend to the left and preferably beyond the rear end
406 of the base 402. The user would ensure that the optical fibers
are oriented in the correct order by running their fingers (or
another appropriate object) along the optical fibers extending from
the stacker 430 to the left. The user would then rotate the stacker
430 downward as the user aligns with the optical fibers with the
recessed channel 420 at the rear end 406. Running a finger or other
appropriate object along the optical fibers and pressing them onto
the bottom surface 422 in the recessed channel 420, which causes
the optical fibers to engage the plurality of ribs 450 and separate
at the appropriate spacing as with the prior embodiments.
[0044] It will be apparent to those skilled in the art that various
modifications and variations can be made to the present invention
without departing from the spirit and scope of the invention. Thus
it is intended that the present invention cover the modifications
and variations of this invention provided they come within the
scope of the appended claims and their equivalents.
