[0013] FIG. 1 shows an embodiment of a fiber array apparatus 100
according to the present disclosure. The fiber array apparatus 100
may include a fiber array unit 10, a packaging plate 20, a
protective cover 30, a spacing plate 40, and a lens plate 50. The
fiber array unit 10 is mounted on the packaging plate 20. The
protective cover 30 can be coupled to the packaging plate 20 and
surrounds the fibers (not labeled) of the fiber array unit 10. The
protective cover 30 may include a first cover 31 and a second cover
32 connected to the first cover 31. The spacing plate 40 can be
connected to one side of the packaging plate 20 away from the fiber
array unit 10, and the lens plate 50 can be connected to one side
of the spacing plate 40 away from the packaging plate 20.
[0014] FIG. 2 illustrates that the packaging plate 20 can be
substantially rectangular. The packaging plate 20 can define a
through hole 21 for mounting the fiber array unit 10. The through
hole 21 can be defined at the central portion of the packaging
plate 20, and the through hole 21 can be rectangular.
[0015] The first cover 31 can be a cover substantially in shape of
a U, the second cover 32 can be a rectangular plate. In other
embodiments, the first cover 31 and the second cover 32 can have
other shapes, as long as both the first cover 31 and the second
cover 32 cooperatively surround a portion of the fiber array unit
10. For example, both of the first cover 31 and the second cover 32
can be U-shaped covers that surround the fiber array unit 10. In at
least one embodiment, the first cover 31 can be connected to the
second cover 32 by screws, and the first cover 31 and the second
cover 32 can be connected to the packaging plate 20 by
adhesive.
[0016] The spacing plate 40 can be a rectangular frame. The lens
plate 50 can be rectangular and mounted to the packaging plate 20
through the spacing plate 40. In at least one embodiment, the
spacing plate 40 can be connected to the packaging plate 20 by
adhesive.
[0017] In at least one embodiment, the fiber array unit 10 can be
fixed to the packaging plate 40 by adhesive. Thus, the fiber array
apparatus 100 may further include a first adhesive layer 61 and a
second adhesive layer 62. The first adhesive layer 61 can be
rectangular and frame shaped. The first adhesive layer 61 may be
arranged around a peripheral portion of the fiber array unit 10.
The second adhesive layer 62 can also be rectangular and arranged
at one side of the packaging plate 40 spaced from the spacing plate
40.
[0018] FIG. 3 illustrates the packaging plate 20 may have an inner
sidewall 22 defining the through hole 21, the packaging plate 20
includes a frame 221 extending from the inner sidewall 22 of the
packaging plate 20 towards the through hole 21. The fiber array
unit 10 and the first adhesive layer 61 can be mounted on the frame
221, and a portion of the fiber array unit 10 can be surrounded by
the first adhesive layer 61.
[0019] FIG. 4 illustrates that the fiber array unit 10 may include
a plurality of substrates 11, a side plate 12, and a plurality of
fibers 13. The plurality of substrates 11 can be parallel and
connected in an array. The side plate 12 can be arranged at one
side of the plurality of the substrates 11, and connected to one of
the substrates 11. The side plate 12 can be a rectangular plate.
The substrates 11 and the side plate 12 are surrounded by the first
adhesive layer 61(shown in FIG. 3). FIG. 5 illustrates the
substrates 11 and the side plate 12 are arranged in a row.
[0020] FIG. 6 illustrates that each of the substrates 11 may be
substantially rectangular, and include a first surface 111 and a
second surface 112 on an opposite side of the substrate 11 from
first surface 111. At least a portion of the second surface 112 can
be planar. The first surface 111 can define a plurality of
positioning grooves 113 and at least one receiving groove 114. The
positioning grooves 113 can be arranged in regular manner. In at
least one embodiment, the positioning grooves 113 can be arranged
substantially parallel and at equal spacing from one another. Each
positioning groove 113 can have a V-shaped cross-section,
configured for receiving one of the fibers 13. In other
embodiments, the positioning grooves 113 can have circular,
rectangular, or other cross-sections, as long as each positioning
grooves 113 can receive and hold a fiber 13.
[0021] The at least one receiving groove 114 may be configured for
receiving an adhesive (not shown). Thus, the substrates 11 and the
side plate 12 can be attached to each other. In an embodiment, the
first surface 111 defines two receiving grooves 114. The two
receiving grooves 114 are defined at opposite sides of the first
surface 111, and the plurality of the positioning grooves 113 are
defined between the two receiving grooves 114. The receiving groove
114 have a rectangular cross-section. In other embodiments, the
receiving grooves 114 can have circular, V-shaped, or other
cross-sections. The width of the receiving groove 114 should be
greater than the width of at least one positioning grooves 113 and
in some embodiments, all the positioning grooves 113 have a same
width.
[0022] FIG. 4 through FIG. 6 show the fibers 13 can be arranged in
an array, with each fiber 13 mounted in a positioning groove 113.
In at least one embodiment, each fiber 13 can be fixed in its
corresponding positioning groove 113 by adhesive. A largest width
of each positioning groove 113 should be greater than a diameter of
the fiber 13 that is positioned within the groove 113. Therefore,
the fiber 13 can be entirely received in its corresponding
positioning groove 113.
[0023] The first surface 111 of each substrate 11 is connected to
the second surface 112 of an adjacent substrate 11 or to the side
plate 12. Thus, the positioning grooves 113 and the ends of the
fibers 13 fixed in the positioning grooves 113 can be covered by
the second surface 112 of the adjacent substrate 11 or the side
plate 12.
[0024] In at least one embodiment, the fiber array unit 10 includes
twenty substrates 11, each substrate 11 defining twenty positioning
grooves 113. Therefore, the fiber array unit 10 can accommodate 400
fibers. In other embodiments, the number of the substrates 11, and
the number of the positioning grooves 113 defined at each substrate
11 may vary.
[0025] In at least one embodiment, the adhesive can be UV-curable.
In other embodiments, the adhesive can be heat curable or similar
types of adhesives.
[0026] In other embodiments, the receiving grooves 114 can be
defined at the second surface 112 of each substrate 11.
[0027] In other embodiments, the number of the receiving grooves
114 defined at each substrate 11 can be one or more.
[0028] In at least one embodiment, the first adhesive layer 61 can
be frame shaped and surround the substrates 11 and the side plate
12. In other embodiments, the first adhesive layer 61 and the
second adhesive layer 62 can form other shapes.
[0029] In some embodiments, each of the positioning holes 113 can
be arranged at different intervals. In other embodiments, some,
rather than all, the positioning holes 113 can be arranged at equal
or different intervals.
[0030] In other embodiments, the positioning holes 113 defined on
different substrates 11 can be staggered.
[0031] The fiber array unit 10 includes a plurality of substrates
11 connected one by one, a side plate 12 arranged at one side of
the plurality of substrates 11 and connected to one of the
plurality of substrates 11, and a plurality of fibers 13. Each
substrate 11 includes a first surface 111 and a second surface 112
on the opposite side of the substrate 11 from first surface 111.
The positioning grooves 113 are defined in first surface 111. The
side plate 12 is connected to the first surface 111 of one of the
substrates 11. Each of the fibers 13 is fixed in a positioning
groove 113. Each substrate 11 can act as a cover plate for covering
the adjacent substrate 11. Therefore, cover plates for the
substrate 11 are unnecessary. The number and density of fibers 13
that can be accommodated in fiber array unit 10 is increased beyond
those of conventional fiber array units. Thus, the fiber array unit
10 provided increased data throughput and space-saving
advantages.
[0032] It is to be understood, however, that even through numerous
characteristics and advantages of the present disclosure have been
set fourth in the foregoing description, together with details of
assembly and function, the disclosure is illustrative only, and
changes may be made in details, especially in the matters of shape,
size, and arrangement of parts within the principles of the
disclosure to the full extent indicated by the broad general
meaning of the terms in which the appended claims are
expressed.
