b, and is fixed by screws 11g (see FIG. 1) together with the lid 14 superposed from the outside. The outer plate portion 11f and the lid 14 project from a plurality of spacer protrusions 15a (see FIG. 3) protruding from the inner lid 15 and the inner surface of the side wall 11k raised around the outer plate portion 11a of the module body 11. Rib 11i etc. (bent part 1
5f and ribs not shown).
Screws (not shown) screwed from holes 11h, 14a, etc.
Is detachably fixed by screwing it to a spacer projection 11c protruding from the module body outer plate portion 11a or to a spacer projection 15a of the inner lid 15.
5 is supported at a position separated by a predetermined distance. Lid 1
4 and the outer plate portion 11f are prevented from dropping into the module main body 11 toward the inside. Projection 11j projecting from the other side of module body 11 opposite optical connector 13
Has a function of positioning with respect to a frame or the like that houses the optical module 10, and its protruding position and necessity of formation can be appropriately selected. The module body 1
The configuration for setting the mounting position of the lid 14 and the storage position of the inner lid 15 in one thickness direction is not limited to the above, and various configurations can be adopted. For example, a configuration in which these lids and the inner lid are positioned only by spacer projections and the like protruding from both surfaces of the inner lid 15, and the inner lid by the spacer projections and the like protruding from the module main body outer plates 11a and 11f and the lid 14. A configuration for positioning or the like can be adopted.

As shown in FIG. 5A, two spaces (an optical fiber housing portion 16 and an optical component housing space 17) are defined inside the module body 11 by the inner cover 15. When the lid 14 is removed from the state shown in FIG.
When the outer plate 11f is also removed, most of the optical fiber housing 16 is exposed and opened, as shown in FIG.

As shown in FIGS. 1, 2, and 3, a working opening 18 is provided on the side of the module body 11, and an optical fiber such as a multi-core optical fiber is provided inside and outside the module body 11. And an optical fiber port 20 for communicating
The openings are spaced apart from each other. The working opening 1
8 between the optical fiber port 20 and the module body 1
It is communicated by a slit 21 formed between the lid 14 attached to 1 and the outer plate portion 11f.

In FIG. 1, the working opening 18 has a shape in which the vicinity of the optical connector 13 of the module main body 11 is cut away, and the optical fiber housing 16 and the optical component housing space 1 are cut out.
7 is communicated. Further, the working opening 18
Has been reached to the vicinity of the optical connector 13 by the cutout 15b formed in the inner lid 15, so that the work inside the module body 11 can be performed by inserting a hand or a tool through the work opening 18. it can. Optical fiber port 20
Is a hole opened on the other side of the module body 11 facing the optical connector 13 and is connected to only the optical fiber housing 16 in FIG. Since both the working opening 18 and the optical fiber port 20 are formed so as to include the boundary between the outer plate 11f and the lid 14, when the lid 14 and the outer plate 11f are attached to the module body 11, A slit 21 is communicated with each of them, and the gap between the working opening 18 and the optical fiber port 20 is communicated by the slit 21.

The slit 21 allows the optical fiber 19 to pass therethrough. Therefore, the module body 11
The optical fiber 19 can be housed in the optical fiber housing 16 in the module main body 11 from the outside through the slit 21 even when the lid 14 and the outer plate 11 f are attached to the optical fiber. The slit 21 shown in FIG. 1 is curved in a substantially S-shape between the working opening 18 and the optical fiber port 20, so that the slit 21 for the optical fiber storage section 16 is formed more easily than the linear slit. It is suitable for storing the optical fiber 19 in a curved shape. The optical fiber 19 accommodated in the module main body 11 in a state where the optical fiber 19 is curved along the curvature of the slit 21.
Is trying to return to a linear shape due to its own rigidity in the module body 11, so that the curved shape when passing through the slit 21 is not maintained. Therefore, the optical fiber 19 after being housed in the module main body 11 from the slit 21 has a shape that cannot pass through the slit 21, thereby preventing the optical fiber 19 from projecting out of the module main body 11, and obtaining a good fit state. The storage workability is improved.

The optical connector 19a, which terminates the end of the optical fiber 19 so as to be connectable to the connector, is inserted through the working opening 18 into the module main body 11 (specifically, the optical fiber housing 16).
Accordingly, the optical fiber 19 can be stored in the module main body 11 including the optical connector 19a at the tip without opening the lid 14. The slit 21 includes the working opening 18 and the optical fiber port 2.
Needless to say, a configuration that extends linearly between 0 and 0 can also be adopted.

As shown in FIG. 4B, a multi-core optical fiber 22 (multi-core optical fiber core) connected to the optical connector 13 from the inside of the module body 11 is provided in the optical component storage space 17 as an optical component. And the like, and a branch portion 23 for branching the optical fiber 22 into a plurality of optical fibers 22a for the plurality of optical connectors 13 is housed. The extra length of the optical fiber 22a branched from the optical fiber 22 is stored in a curved state by being wound around a mandrel 17a in the optical component storage space 17, for example. Since the optical component storage space 17 is separated from the optical fiber storage section 16 by the inner cover 15,
The work of storing the optical fiber 19 into the optical fiber storage section 16 after passing through the slit 21 prevents the optical components 22 and 23 stored in the optical component storage space 17 from vibrating and affecting the optical characteristics. it can. Therefore, the work of storing the optical fiber 19 in the optical fiber storage section 16 can be performed efficiently without having to pay attention to the contact with the optical components 22 and 23 stored in the optical component storage space 17. In the optical component storage space 17, an optical fiber or the like in which an optical component such as an optical coupler or an optical filter is interposed can be stored. Also in this case, by storing the optical component in the optical component storage space 17, the influence of the operation of storing the optical fiber 19 in the optical fiber storage section 16 can be avoided. The optical components such as the optical coupler and the optical filter are housed in the optical component storage space 17 by the guide walls 11.
It is also possible to store in the storage space 17b defined by d and 11e. In the storage space 17b, the guide walls 11d and 11e prevent the optical components housed therein from coming into contact with the optical fibers 22 and 22a, so that the optical fiber 22 is pulled out or stored in the optical fiber storage space 16. Even if the operation (described later) is performed, the optical characteristics of the optical component can be stably maintained.

As shown in FIG. 3, between the optical fiber storage section 16 and the optical component storage space 17, the inner lid 15 is provided.
Are communicated through a communication portion 15c formed in the first portion. 3 and FIGS. 5 (a), 5 (b), and 5 (c), the communication portion 15c is provided at the rear portion of the inner cover 15 which is spaced apart from the optical connector 13 of the module main body 11 (in FIG. Side, right side in FIGS. 5 (a) and 5 (b))
d is a gap formed by being folded into one of the optical fiber storage section 16 and the optical component storage space 17 (in the present embodiment, folded toward the optical component storage space 17). The inner lid 15 has a plate shape integrally formed from a resin such as plastic, and the optical fibers 19 and
22 is not damaged. It is preferable that the tongue piece 15d can be easily bent and formed manually.

As shown in FIGS. 2 and 3, one end of the optical fiber 22 branched into a plurality of optical fibers 22a by a branching portion 23 has an end opposite to the multi-fiber optical connector 24. The connector is terminated so as to be connectable to a connector, and is drawn into the optical fiber storage section 16 from the optical component storage space 17 via the communication section 15c. A portion of the optical fiber 22 in the vicinity of the optical connector 24 is bent and stored in the optical fiber storing portion 16, and is pulled up to the working opening 18, and the connector holding portion provided on the inner lid 15 is provided. By 25, it is detachably held. Thus, the optical connector 24 is prevented from dropping into the module main body 11, and can be easily taken out at any time.

In FIGS. 1 and 2, the multi-core optical fibers 19 and 22 employ optical fiber ribbons, and the multi-core optical connectors 19a and 24 at the ends of the optical fibers 19 and 22 are used. Is a so-called MT optical connector (Mecanically Transcribed by JIS C5981).
sferable). However, various configurations such as a multi-core optical cord can be adopted as the multi-core optical fiber. As a multi-fiber optical connector for connecting optical fibers, MT
Various optical connectors other than the optical connector can be adopted.

Further, as the connector holding portion 25, one that is integrally formed with the inner lid 15 in the vicinity of the cutout portion 15b is employed. The connector holding portion 25 is provided with the slit 2
The optical connectors 19a and 24 are removably housed in the recess 25b by sandwiching the optical fibers 19 and 22 between the optical fibers 5a and 5a. The connector holding portion is not limited to the above-described configuration. For example, the configuration is not a separate configuration in the inner lid 15 or a configuration in which the optical connectors 19a and 24 are directly detachably inserted, instead of a configuration in which the optical fibers 19 and 22 are inserted. Various configurations can be adopted. The installation position of the connector holding portion is not limited to the inner cover as long as it is inside or near the working opening 18, and may be the module body outer plate portion 11 a or the cover 14. However,
In the case where the optical fiber is attached to the module body outer plate portion 11a or the portion facing the optical component storage space 17 of the inner lid 15, a sufficient bending radius is provided for the optical fiber drawn from the optical fiber storage portion 16 through the working opening 18. Be able to secure.

As shown in FIG. 1, the tip of the optical fiber 19 led out to the terminal of the optical cable 26 is connected to the optical module 10.
The optical fiber 19 is connected to the optical fiber 22 on the optical module 10 side by connecting the optical connectors 19a and 24 to each other so that the optical connector 19 can be connected to the optical module 13 by the optical connector 13. Thereby, the optical fiber 19 is optically connected to the plurality of optical connectors 13 via the optical fiber 22,
The optical fiber 13 is connected to another optical fiber 12 via the optical connector 13 so as to be connectable to the optical fiber 12. In connection work between the optical connectors 19a and 24, the optical connector 24 at the tip of the optical fiber 22 is taken out from the connector holding portion 25, and further,
The optical fiber 22 is pulled out using the extra length stored in the optical fiber storage section 16 to perform a connection operation. For example, eight optical fibers 19 are connected to the optical connectors 19a, 24a.
Is connected to the same eight-core optical fiber 22 on the module side, is branched into eight single-core optical fibers 22a via the optical fiber 22, and is connected to the single-core SC optical connector 13. The optical fiber 19 is connected to the single-core optical fiber 12 which is connected to the SC type optical connector 12a.

The optical connectors 19a and 24 in the connected state are held in the connector holding section 25 through the working opening 18. The extra length of the optical fiber 22 on the module side pulled out for the connection work with the optical fiber 19 is, together with the extra length of the optical fiber 19, from the working opening 18 into the module main body 16 (specifically, the optical fiber housing 16. Inside) and store it in a curved shape. Therefore, the connection work between the optical fibers 19 and 22 and the optical fibers 19 and 22 and the optical connector 1 after the connection are performed.
The storing work of 9a and 24 can be performed without opening the module main body 11, and the opening and closing work of the module main body 11 can be omitted, and the workability can be improved.

If the optical connectors 19a and 24 in the connected state are taken out from the connector holding portion 25, the optical fibers 19 and 22 and the optical connectors 19a and 24 can be taken out from the module main body 11 (specifically, from the optical fiber housing portion 16). Can be. Since the optical connectors 19a and 24 in the connected state are held by the connector holding portion 25, the optical connectors 19a and 24 are prevented from dropping into the module main body 11, and can be easily taken out. When the connection between the optical connectors 19 a and 24 is released, the optical fiber 19 can be pulled out from the optical fiber port 20 and pulled out from the optical module 10. The connection and disconnection operations should be performed efficiently without affecting the optical components 22 and 23 in the optical component storage space 17 partitioned by the inner lid 15 with respect to the optical fiber storage unit 16. Can be. Further, in some cases, it is needless to say that the lid 14 and the outer plate portion 11f can be opened to correct the wiring state of the optical fibers 19 and 22 in the optical fiber housing portion 16 and the like. .

In particular, in the optical module 10 housed in a terminal frame or the like, the working opening 18, the optical fiber port 20,
If the optical fiber 19 and 22 are pulled out of the storage place to the extent that the slit 21 is exposed, the connection between the optical fibers 19 and 22 and the optical fiber 1
9, the extra work of storing the extra length of the optical module 10 taken out of the storage location can be performed on the work table, and the work of transferring the optical module 10 between the storage location and the work table is unnecessary. And workability can be greatly improved. There is no need to secure a workbench installation space or the like around the storage space for the frame or the like.

In the above-described embodiment, the optical module 10 in which the multi-core optical fiber 19 is connected by the optical connector 13 so as to be connectable to the connector is illustrated. However, the present invention is not limited to this. It is also possible to adopt a configuration in which the optical fiber of the core is terminated by an optical connector on the side of the optical module so as to be connectable to another optical fiber. It is also possible to adopt a configuration in which an optical fiber housed in the module main body from the outside is directly connected to the optical connector on the side of the module main body without passing through the optical fiber on the module side. The module body is not limited to a configuration in which the interior is partitioned by an inner lid and an optical fiber storage section and an optical component storage space are defined, and the module body is not provided with an inner lid and is partitioned into a plurality of spaces. No configuration is possible. In the present invention, a configuration without a cover or the like that can be opened and closed can be adopted.

In the above embodiment, the optical fiber 1 terminated so as to be connectable to the connector by the optical connector 19a is used.
Although the application example of No. 9 has been described, the present invention is not limited to this, and is also applicable to an optical fiber that is not terminated so as to be connectable to a connector. For example, a configuration in which an external optical fiber is fusion-spliced with an optical fiber on the module side and optically connected to an optical connector on the module main body side can be adopted. In this case, the fusion spliced portion between the optical fibers is
By facilitating removal of the fusion spliced part when disconnecting it, it is housed in the module main body through the work opening on the side of the module main body or held in the fusion part holder near the work opening. it can.
