DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber aligner for aligning optical fibers, and more particularly, to an optical fiber wired so as to be pulled out of an aligner body and pulled back to the aligner body. The present invention relates to an optical fiber alignment board as described above.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional optical fiber alignment board. In FIG. 6, the optical fiber alignment board 1 is
Optical component storage unit 2 for storing optical components such as optical couplers
And a plurality of optical fibers 4 (mainly optical cords) drawn out from the jumper unit 3 and arranged between the jumper unit 3 and the jumper unit 3. The optical fiber 4
Is switchably connected to an optical connector (not shown) of the optical component storage unit 2. Since the plurality of optical fibers 4 aligned by the optical fiber alignment board 1 are prevented from being entangled with each other, operations such as switching connection to the optical component storage unit 2, addition, and removal are easy. At the time of switching connection, the optical fiber 4 pulled out from the optical fiber alignment board 1 to the jumper unit 3 is pulled so that the tip of the optical fiber 4 terminated by the optical connector 5 (optical connector plug) is connected to the optical fiber alignment board. 1 to the optical component storage unit 2
Wiring and connection to the target optical connector on the side again (so-called plug reset). Thereby, the optical fiber (not shown) connected to the optical fiber 4 by the jumper unit 3
Can be connected to a target optical line (optical connector) on the optical component storage unit 2 side via the optical fiber 4.

In FIG. 6, an optical fiber alignment board 1 has a plate-shaped alignment board main body 1a which is horizontally installed. FIG. 7 is a perspective view of the alignment board main body 1a as viewed from the lower surface side. As shown in FIG. 7, in the aligning body 1a, the optical fibers 4 are inserted one by one into a large number of through holes 1b and aligned. The through hole 1b also functions as a plug hole to which the optical connector 5 at the tip of the optical fiber 4 can be attached and detached. Therefore, the optical connector 5 at the end of the optical fiber 4a in a connection pending state, which is not connected anywhere, can be mounted in the through hole 1b and protected. FIG.
Reference numeral 1c denotes an extra length storage portion, which absorbs the extra length of the optical fibers 4 and 4a by using a winding shaft 1d and the like provided inside.

[0004]

However, FIG.
In the optical fiber alignment board 1 shown in FIG. 7, the through-holes 1b are large enough to mount the optical connector 5, and a large number of through-holes 1b correspond to the number of optical fibers 4 to be aligned.
When b is provided, there is a problem that the size of the aligning panel main body 1a becomes large, and it becomes difficult to install a large number on a frame or the like. For this reason, the number of installations on the rack etc. is a number designed in advance,
Updating or removing as appropriate has not been considered much. The processing of the optical fiber 4a in the connection hold state is as follows.
Since the optical connector 5 is mounted in the through hole 1b, there is a problem that the optical fiber 4 around the center of the alignment board body 1a hinders the work of attaching and detaching the optical connector 5 to and from the through hole 1b. is there. In particular, when the connection of the optical fiber 4a in the reserved state is used, there is a problem that the optical fiber 4a taken out from the through hole 1b is easily entangled with another optical fiber 4 and is difficult to take out. The optical connector 5 in the suspended state cannot be dust-proofed from the opening on the opposite side of the through-hole 1b simply by being attached to the through-hole 1b. Therefore, it is necessary to attach a cap. There was a problem that it took time. Further, on the jumper unit 3 side of the optical fiber alignment board 1,
A large number of optical fibers 4 are in a complicated state on the horizontally arranged alignment board main body 1a, and it takes time and effort to find the target optical fiber 4 to perform the plug resetting operation. However, if a separate extra length storage section is provided, disadvantages such as an increase in size, an increase in cost, and a longer duration of extra length processing work are caused, and the problem is not fundamentally solved. As described above, the conventional optical fiber alignment board 1
Thus, although a certain effect can be obtained by arranging a large number of optical fibers 4 and plug resetting, the size, workability of installation and removal, plug reset workability, and the like need to be improved.

[0005] The present invention has been made in view of the above-mentioned problems, and can be reduced in size, can be easily added or removed, and
Moreover, it is an object of the present invention to provide an optical fiber alignment board capable of efficiently performing operations such as plug reset.

[0006]

The present invention has the following features to attain the object mentioned above. That is, in the present invention, a case-shaped alignment plate main body, an alignment portion formed by aligning and opening a plurality of optical fiber insertion holes on one side of the alignment disk main body, and facing the alignment portion of the alignment plate main body. A drawer formed by aligning and opening a plurality of optical fiber insertion holes on the other side of the optical fiber insertion hole, the optical fiber insertion holes of the alignment portion and the extraction portion each being allowed to move in the optical fiber insertion hole axial direction. An optical fiber alignment board is characterized in that the optical fiber penetrated by the optical fiber is aligned and drawn into the alignment board body. According to a second aspect of the present invention, in the optical fiber alignment board according to the first aspect, of the optical fibers drawn outward from the alignment section, an optical fiber end that is not connected anywhere is connected to a connector. A connector holding portion for holding the terminated optical connector so as to be able to be taken out is provided near the alignment portion. According to a third aspect of the present invention, in the optical fiber alignment board according to the first or second aspect, a jumper unit for connecting an optical fiber drawn out from the optical fiber insertion hole of the drawing portion to the outside with another optical fiber is integrated. The jumper unit mounting portion is attached to the optical fiber, and the optical fiber pulled out from the optical fiber insertion hole of the drawer portion toward the jumper unit is curved and wired from the drawer portion to the jumper unit. It is characterized by having.

According to the optical fiber alignment board of the present invention, in order to perform switching connection and the like of the optical fiber drawn out from the optical fiber insertion hole of the alignment section, the optical fiber is drawn out from the optical fiber insertion hole of the extraction section. By pulling the optical fiber, the end of the optical fiber pulled out from the optical fiber insertion hole of the alignment section is pulled back to the vicinity of the alignment section (plug reset). Since the main body is composed of the case-shaped alignment board main body, it can be easily added to or removed from a frame or the like.
According to the second aspect of the present invention, the optical connector at the end of the optical fiber that is not connected can be protected from dust and the like by being detachably held in the connector holding portion near the alignment portion. In addition, since the connector holding section is provided separately from the alignment section, it is easy to take out an unconnected optical fiber when connected and used. According to the third aspect of the present invention, when the jumper unit mounting portion is provided, the drawer and the jumper unit can be brought close to each other, and the jumper can be maintained while the optical fibers drawn from the drawer are almost aligned. Wired to the unit. Therefore, when performing a plug reset operation or the like, it becomes easy to find a target optical fiber.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. 1 and 2, an optical fiber alignment board 10 according to the present embodiment has a case-shaped alignment board main body 11 and a plurality of optical fiber insertion holes 12 arranged on one side 11a of the alignment board main body 11 so as to be opened. And a drawer 15 formed by aligning and opening a plurality of optical fiber insertion holes 14 on the other side 11b of the aligner body 11 facing the aligner 13. In FIGS. 1 and 2, the alignment board main body 11 is in the shape of a thin external case, and is provided with a jumper unit mounting portion 16 in which a lower portion is cut off. The jumper unit 1 detachably attached to the jumper unit attachment portion 16
7 is formed in the shape of an external thin plate like the main body 11 of the aligner, and when attached to the main body 11 of the aligner, the whole is assembled into a unit having a thin external rectangular shape. As a mechanism for attaching and detaching the jumper unit 17 at the jumper unit attachment section 16, various configurations are conceivable.
In (b), a detachable piece 16a protruding from the jumper unit attaching portion 16 is used as a detachable mechanism. As shown in FIG. 3, a plurality of the optical fiber alignment boards 10 are vertically and horizontally arranged in a rack-like storage section of a frame such as an optical wiring board.

Note that the alignment board body 11 is not limited to the appearance of a thin plate case, and various other shapes can be adopted. The jumper unit 17 is not limited to the external thin case shape, but various shapes can be adopted. In addition, the jumper unit mounting portion 16 for mounting the jumper unit 17 is not limited to a shape in which a part of the alignment plate main body 11 in the form of an external thin plate is cut out, and is installed so as to be adjacent to the alignment plate main body. Various configurations can be adopted, such as a configuration in which the jumper unit is detachably supported, and a configuration in which the jumper unit is retractably housed inside the alignment panel body.

FIG. 4 is a view showing the details of the optical fiber alignment board 10, in which FIG. 4 (a) is a rear view as viewed from the alignment section 13, FIG. 4 (b) is a side view, and FIG. () Is a front view as viewed from the drawer 15 side. 4 (a), 4 (b) and 4 (c), an optical fiber 18 drawn from a jumper unit 17 is passed through the drawer 15 to the aligner 13 in the aligner body 11. Alignment section 1 of this optical fiber 18
3 is pulled out by the optical connector 19.
It is terminated so as to be connectable to a connector, and is connected to a connection unit (not shown) by a connector. As the connection unit, an optical component storage unit such as a coupler unit having a built-in optical coupler, or a termination unit in which a plurality of ends of optical fiber connectors terminated are arranged. In the optical fiber alignment board 10, the optical fiber insertion hole 12 of the alignment section 13 and the optical fiber insertion hole 14 of the extraction section 15
The plurality of optical fibers 18, each of which is allowed to move in the axial direction of the optical fiber insertion hole and penetrates, are aligned and drawn in the alignment board main body 11 without intersecting each other on the way. Therefore, in this optical fiber alignment board 10,
The optical fibers 18 are consistently arranged and wired in a certain order in the vicinity of the alignment section 13, the drawer section 15, and in the alignment board main body 11.

The optical connector 19 at the end of the optical fiber 18a, which is not connected to anywhere, can be taken out of the optical fiber 18 drawn out of the aligning portion 13 from one side 11a of the aligning body 11. The connector holding portion 20 is provided near the alignment portion 13.
In the present embodiment, the optical fiber 18 is a single-core optical cord, and the optical connector 19 is an SC type optical connector (Single fiber Coupling optical connector) defined in JIS C5973.
fiber connector), the connector holding part 20 is also S
This is an optical connector adapter of a C-type optical connector, and an optical connector 19 is detachable. The optical connector 19 connected to the connector holding section 20 is prevented from adhering dust and the like,
Optical characteristics are stably maintained. Note that the optical connector holding section is not limited to the optical connector adapter, and various configurations can be adopted as long as the optical connector is configured to hold the optical connector in a removable manner. The connector holding units 20 are arranged on both upper and lower sides (upper and lower sides in FIGS. 4A and 4B) of the alignment unit 13. In an optical connector adapter to which the optical connector 19 can be attached and detached, the space can be saved and the density can be increased by using multiple connectors, and the protection and the attaching and detaching workability of the ferrule built in the optical connector 19 can be ensured. ,
More preferred. The connector holding portion 20 does not require a dust cap or the like. In addition, as the optical fiber 18,
A multi-core optical fiber core, an optical cord, or the like can be adopted. At this time, as the optical connector 19 (optical connector plug), for example, the MT defined in JIS C5981 is used.
Optical connector (Mecanically Transferable), JIS
MPO type optical connector (Mult
Ifiber Push On) is adopted, and the optical connector holding unit 20 is used.
Also, an optical connector adapter compatible with the optical connector 29 is employed.

Since the optical connector 19 for which connection is suspended is processed by the connector holding unit 20, the optical fiber insertion holes 12 and 14 of the alignment unit 13 and the lead-out unit 15 are all large enough to insert the optical fiber 18. It is not necessary to form the optical connector 18 as large as the conventional example shown in FIG. For this reason, both the alignment section 13 and the lead-out section 15 can be formed in a small size, and can cope with the alignment of many optical fibers 18 in a small space. Each of the optical fiber insertion holes 12 and 14 is large enough to lightly contact the outer surface of the optical fiber 18 or to form a slight gap. The fiber 18 is constrained to a certain range to prevent unnecessary floating near the alignment unit 13 and the drawer unit 15. Accordingly, it is possible to reliably prevent inconveniences such as the optical fibers 18 in the vicinity of the alignment unit 13 and the lead-out unit 15 being entangled by floating.

The extra length of the optical fiber 18a in the connection hold state is dropped so as to hang outside the vicinity of the alignment section 13,
Furthermore, it is processed by turning upward. Therefore, the extra length of the optical fiber 18a is set in the same wiring route as the other optical fibers 18 connected to the connection unit by a connector in the vicinity of the alignment portion 13, and is separately provided as a space for storing the extra length. There is no need to secure On the other hand, the optical connector 19 has a connector holding portion 2 that is different from the alignment portion 13.
Since it is held at 0, it can be easily distinguished from the other optical fibers 18 wired to the alignment section 13, and the workability of taking out when connecting and using can be secured. In FIG. 2, reference numeral 21 denotes an extra length storage portion formed by a frame, and
The extra length of the wires 8 and 18a is housed in a predetermined area by being pulled down into the extra length accommodation portion.

As shown in FIGS. 4B and 4C, the optical fiber insertion holes 14 of the drawer 15 are arranged at a wider arrangement pitch than the optical fiber insertion holes 12 of the alignment unit 13.
The optical fiber 18 drawn out of the optical fiber insertion hole 14 of the drawer 15 is bent into a reverse turn and pulled into the jumper unit 17 from the optical fiber hole 17a while maintaining the arrangement order substantially. Drawer 15
In the vicinity, since the optical fibers 18 are aligned and drawn out at a wider pitch than the aligning portion 13 due to the arrangement pitch of the optical fiber insertion holes 14, the target optical fiber 1
The operation of pulling out 8 is easy. Aligner body 1
In FIG. 1, the plurality of optical fibers 18 are passed almost in parallel between the alignment unit 13 and the extraction unit 15 while maintaining a fixed alignment order. From the difference in the arrangement pitch of the optical fiber insertion holes 12 and 15
The distance between the adjacent optical fibers 18 gradually increases from the alignment section 13 to the drawing section 15. In FIG. 4B, reference numeral 22 denotes a guide member, which presses the optical fiber 18 so as not to generate vibration while allowing the optical fiber 18 to slide in its length direction.

As shown in FIGS. 4 (a) and 4 (c), the optical fiber insertion holes 12 and 14 are respectively provided in the alignment board main body 11.
The slits 11e cut from the edges of the end plates 11c and 11d forming the side surfaces communicate with each other. Aligner body 11
Is formed by assembling members made of resin or the like such as plastic, and the end face plate 1 exposed at the time of disassembly.
By passing slits 11e from the edges of 1c and 11d,
The optical fiber 18 can be easily inserted into the optical fiber insertion holes 12 and 14. When the aligning body 11 is assembled, the removal of the optical fiber 18 from the slit 11e is restricted. When disassembling the aligner body 11, the slit 1
The optical fiber 18 can be extracted from the optical fiber insertion holes 12 and 14 through 1e.

As shown in FIG. 4B, the optical connector adapter 17b attached to the side of the jumper unit 17
The optical fiber 1 from the inside of this jumper unit 17
8 are connected via an optical splitter 23. And
Another optical fiber 24 connected from the outside to the optical connector adapter 17b is branched and connected to the plurality of optical fibers 18 via the optical splitter 23. In the present embodiment, the aligner body 1
On one side 11a (the side of the aligning section 13), a total of four 8-unit optical connector adapters are arranged as the connector holding section 20, and in the aligning section 13 and the drawer section 15, 32 optical fibers 18 are aligned. It can be processed. On the other hand, the jumper unit 17 can cope with the connection of a total of 16 optical fibers 24 by attaching two 8-unit optical connector adapters 17b. In the optical splitter 23, the line for one optical fiber 24 is connected to two lines. The optical fiber 18 is branched and connected. The present invention is not limited to this, and it is needless to say that the number of optical fibers, the number of optical fibers, the number of line branches by the optical splitter 23, and the like can be appropriately changed.

A wiring route is required for the optical fiber 18 wired from the jumper unit 17 to the connection unit via the optical fiber alignment board 10 by a frame or the like, for example, by changing the connection destination. When the optical fiber 18 is pulled out from the drawer 15 as shown in FIG.
Of the optical fiber 18
Once the wire is pulled back to the vicinity of the alignment portion 13, wiring, connection work, and the like to a target connection destination are newly performed. Since the optical fiber insertion hole 12 of the alignment section 13 is sufficiently smaller than the optical connector 19 at the end of the optical fiber 18, the optical connector 18 does not fall into the alignment board main body 11 when the optical fiber 18 is pulled back. Pulling back 18 can be continued until the optical connector 19 comes into contact with the wall 13a of the alignment section 13 (when the optical connector 19 comes into contact, the plug is reset). Here, in the drawer 15, the optical fiber insertion hole 14
Since the arrangement pitch of the optical fibers 18 is expanded by the arrangement pitch of the optical fibers 18 as compared with the arrangement side, it is easy to find out the target optical fiber 18 and pull it back as if pulling it. Is improved.

In order to suspend the connection of the pulled back optical fiber 18 without immediately wiring and connecting the end, the optical connector 1
9 may be connected to the optical connector adapter which is the connector holding unit 20. At this time, the processing can be easily performed only by turning the end of the optical fiber 18 upward and connecting the optical connector 19 to the optical connector adapter. At this time, the work of connecting the optical connector 19 to the optical connector adapter and the work of processing the excess length are work on the side of the optical fiber alignment board 10, and the alignment work is performed as in the prior art shown in FIG. Workability is improved as compared with work on the lower side of the panel. The workability of taking out the holding optical fiber 18 can be similarly improved.

According to the optical fiber alignment board 10, the work of pulling back the optical fiber 18 and rewiring can be efficiently performed. Further, the processing of the optical fiber 18 for which connection is suspended, the taking-out work at the time of using the connection, and the like can be performed efficiently. In addition, in the optical fiber alignment board 10, the jumper unit 17 can be installed in a target storage unit such as a frame with the jumper unit 17 attached. Wiring of the optical fiber 18 and the like inside can be performed before installation in the storage unit. Since installation can be performed, installation workability is also improved. Moreover, the jumper unit mounting portion 1
6 and the drawer 15 of the optical fiber alignment board 10 are arranged close to each other, and the length of the optical fiber 18 wired so as to pass between them can be short. The bending process and the extra length process can be simplified, and the effect of improving the wiring workability can be obtained.

Further, in the optical fiber alignment board 10, the workability of processing and taking out the optical fiber 18 for which connection is suspended can be improved by the connector holding part 20 different from the alignment part 13, and the alignment part 13 and the drawing out part can be improved. On the other hand, the optical fiber insertion hole 12 and the optical fiber insertion hole 15 can be formed at a high density in the part 15, but the connector holding part 20 can hold the optical connector 19 at a high density. Miniaturization is possible. The arrangement pitch of the optical fiber insertion holes 12 of the alignment section 13 is smaller than that of the optical fiber insertion hole 14 of the drawer section 15, and the alignment section 13 can be downsized, which also contributes to downsizing of the optical fiber alignment board 10. Further, as in the present embodiment, in the optical fiber alignment board 10 mainly including the alignment board main body 11 in the form of a thin external case, compared with the conventional alignment board shown in FIG. Storage density can be improved. Moreover, it is easy to add, remove, and relocate the storage unit, and there is an advantage that relocation can be easily performed together with the optical fiber 18 in units of one unit. The addition, removal, and relocation of the optical fiber alignment board 10 can be performed integrally with the jumper unit 17 mounted on the jumper unit mounting portion 16. For this reason, there is an advantage that it is possible to easily cope with the addition, removal, and relocation of the optical fiber 18 on a frame or the like.

The plug resetting operation can be automated. For example, as shown in FIG. 5, the position reading sensor 25 detects the optical fiber insertion hole 1 of the drawer 15.
When the position of the optical fiber 4 is read optically or electromagnetically, and the optical fiber 18 pulled out from the target optical fiber insertion hole 14 is pulled by a special pulling device (not shown), the target optical fiber 18 Plug reset can be automated. In this automated plug reset, it is preferable that the detachment of the optical connector 19 from the connection destination of the optical fiber 18 can be automatically performed. The detection of the optical fiber insertion hole 14 by the position reading sensor 25 is not limited to the detection of the optical fiber insertion hole 14 itself. For example, a conductive component provided for each optical fiber insertion hole 14 or an electromagnetic A component for recording a signal or the like may be detected. In particular, when reading a magnetic tape or the like in which signals are stored electromagnetically, it can be used to record work history information such as the frequency of plug reset.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the installation position and the number of the connector holding portions, the number of the alignment portions and the drawer portions corresponding to the optical fibers, and the like can be appropriately changed. Further, in the optical fiber alignment board of the embodiment, the aligning portion and the drawer portion having the configuration in which the plurality of optical fiber insertion holes are arranged in a line are illustrated, but the aligning portion and the drawer portion have two optical fiber insertion holes. A configuration in which rows are arranged in parallel or more can be adopted. However, in a configuration in which a plurality of optical fiber insertion holes are provided in a row on one side and the other side of the thin plate case-shaped alignment board body, the purpose is to use a large number of optical fibers drawn from each optical fiber insertion hole. There is an advantage that it is easy to find things, and it is easy to take out and pull out. Further, similarly, the installation position and the like of the connector holding portion can be variously changed, but as in the above-described embodiment, the alignment portion and the drawer portion can be used.
If the optical fiber insertion holes are arranged in a row in a row that is continuous with the alignment, there is an advantage that the processing and extraction of the target optical fiber become easy.

And a drawer portion formed by aligning and opening a plurality of optical fiber insertion holes on the other side of the aligner body opposite to the aligner, and the optical fibers of the aligner and the drawer. The optical fiber, which is allowed to move in the axial direction of the optical fiber insertion hole and penetrates through the insertion hole, is aligned and drawn into the main body of the alignment board. Even in the vicinity, since the optical fibers are aligned neatly, the operation of pulling out the target optical fiber to the alignment portion by operating the drawer (plug reset)
Can be performed efficiently, and workability is improved. Also,
This optical fiber alignment board is excellent in workability of addition, removal and relocation, so that it can respond quickly and easily to changes in the number of cores supported by frames such as optical distribution boards and changes in optical fiber wiring routes. It has excellent effects. According to the optical fiber alignment board according to the second aspect, the optical connector at the end of the unconnected optical fiber is detachably held by the connector holding portion near the alignment portion, so that it can be protected from dust and the like. .
Further, since the connector holding portion is provided separately from the alignment portion, it has an excellent effect that it is easy to process an unconnected optical fiber and to easily take out the optical fiber when connecting and using. Claim 3
According to the described optical fiber alignment board, by providing the jumper unit mounting portion, the drawer and the jumper unit can be brought close to each other, and the wiring length of the optical fiber between the drawer and the jumper unit can be greatly increased. The length of the optical fiber can be shortened, and the bending process and the extra length process of the optical fiber can be simplified. In addition, it is possible to perform the wiring of the optical fiber between the optical fiber alignment board and the jumper unit before installation on a frame or the like, which has an advantage that the assembling workability and the installation workability are improved. is there. Further, the fact that the jumper unit and the optical fiber alignment board can be integrally added, removed, and relocated also has an excellent effect of contributing to an improvement in assembly workability and installation workability.
