Two storage spaces 6 and 7 are defined in the thickness direction via the partition member 5. The storage space 6 defined on one side of the partition member 5 stores the excess length of the optical fiber 4 in a curved shape, and the storage space 7 defined on the other side of the partition member 5 includes the optical connector 3. An optical connector 9 (optical connector, fusion splicer, etc.) between the internal optical fiber 8 and the optical fiber 4 connected thereto is housed. The optical fiber 4 is wired so as to communicate between the storage spaces 6 and 7 via a communication hole 10 opened in the partition member 5. One end of the internal optical fiber 8 is branched into, for example, 1: 4, 1: 8, or the like. By connecting the tip of the optical fiber 4 to the end of the internal optical fiber 8 on the side where it is not branched, The optical fiber 4 is branched and connected to the optical connector 3 in a plurality. As the optical fiber 4, an optical fiber in which a terminal is branched into a plurality of branch optical fibers terminated so that a connector can be connected to the optical connector 3 from the inside of the optical module 1 can be adopted. The terminal of the optical fiber 4 drawn into 1 can be directly connected to the optical connector 3, and the connection with the internal optical fiber 8 can be omitted.

A part of the optical connector 40 fitted in the connector hole 34a opened at the bottom is housed.

The extra length of the optical fiber 41 is curved and stored in one storage space 22 (hereinafter sometimes referred to as the “input-side storage space 22”). In the other storage space 21 (hereinafter sometimes referred to as “output storage space 21”), the partition member 36 is connected to the input storage space 22 through a communication hole 36 a formed by cutting one side of the partition member 36. The optical fiber 41 communicates with and is wired to the optical fiber 41, and an optical connector 42, which is an optical connector plug provided at the tip of the optical fiber 41, is connected to the optical connector 40. Thereby, the optical fiber 41
Is terminated so as to be connectable to an optical fiber that is separately connected to the optical connector 40 from the outside via the optical connector 40.

The optical fiber 41 is connected to a multi-core optical fiber section 41a composed of a multi-core optical fiber cord (here, a 4-core optical fiber cord) and the like, and a branch section 43 from a terminal of the multi-core optical fiber section 41a. For example, a plurality of (e.g., four in this case) branched into 1: 4, 1: 8, and the like (here, 1: 4 branch).

The optical component holders 24 and 25 are composed of projections protruding from the partition member 36, and can hold an optical connection portion such as a fusion splicing portion or an optical connector in a removable manner. The optical component holders 24 and 25 can hold various optical components other than the optical coupler, such as an optical filter. In the storage space 21, the optical components to be stored are stored in the optical component holders 24 and 25.
The optical fiber 41 can be stably accommodated, and it is possible to minimize the possibility that contact due to movement caused by operations such as replacement and removal of the optical fiber 41 and vibration applied to the optical module 20 as an external force adversely affect the optical characteristics of the optical component. Can be prevented.

The input side storage space 22 is connected to the wiring hole 3b of the connector mounting wall 34 through a through hole 35b defined by a partition wall 35a which partitions the output side storage space 21.

That is, the optical connector 40 is provided with a pair of mounting pieces 40b protruding from both sides of the sleeve-shaped housing 40a facing each other. As shown in FIGS. One mounting piece 40b is fitted into a groove-shaped connector positioning hole 36b formed in the partition member 36 near the hole 34a, and the other mounting piece 40b is inserted into a groove-shaped connector positioning hole 31a formed in the lid 31. It is fitted and stably mounted at a predetermined position. As shown in FIGS. 5A and 5B, holes 40c are formed in the mounting pieces 40b on both sides of the optical connector 40, and the mounting pieces 40b fitted in the connector positioning holes 36b of the partition member 36 are provided. The optical connector 40 is stably supported by removably fitting the hole 40c into the fitting protrusion 36c protruding from the inner surface of the connector positioning hole 36b of the partition member 36. The connector positioning hole 31a on the lid 31 has no fitting protrusion fitted into the hole 40c of the other mounting piece 40b of the optical connector 40. When the lid 31 is opened, the mounting piece 40b is pulled out from the connector positioning hole 31a, The optical connector 40 supported by the frame 51 (specifically, the partition member 36) is exposed. The optical connector 40 can be easily removed from the module main body 30 simply by opening the lid 31 of the module main body 30, pulling the optical connector 40 strongly, and pulling out the mounting piece 40b from the connector positioning hole 36b of the partition member 36. . Then, by pulling out the optical connector 42 at the tip of the optical fiber 41 connected to the optical connector 40 from the optical connector 40 taken out from the module main body 30, a place where a sufficient working space outside the module main body 30 can be secured. In addition, work such as cleaning of the inside of the optical connector 40 can be efficiently performed. Further, if the lid 31 is opened, the optical connector 4 can be simply inserted by pushing the mounting piece 40b into the connector positioning hole 36b of the partition member 36.

The formation position of the connector positioning hole on the frame portion 51 side is
The material is not limited to the partition member 36 and may be anywhere near the connector mounting wall 34 of the frame portion 51.

The anchoring part 38 shown in FIG.
By opening the lid 32 opposite to the above, the side portion of the wiring hole 35 can be opened, so that operations such as storage, removal, and replacement with respect to the wiring hole 35 can be easily performed.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the above-described embodiment, the configuration has been described in which the entire side walls 31, 32 and the entire rear wall 33 of the module main body 30 function as lids that can be freely opened and closed, but the present invention is not limited to this. It is also possible to adopt a configuration in which a part of each side wall part and a part of a rear wall part on both sides of the module body function as a lid that can be opened and closed. Further, the lid that opens and closes the whole or one part of the both side walls and the lid that opens and closes the whole or one part of the rear wall is not limited to the above-described lid member 52, and a part of the module body is hinged. A configuration that functions as a lid that is rotatably connected can also be adopted. However, if the cover member 52 is detachable from the module main body, it does not become an obstacle if it is detached from the module main body, and operations such as storage and removal of the optical fiber into and from the storage space and the communication hole on both sides via the partition member. This is advantageous in that excellent workability can be obtained because it does not cause interference.

The partition member is not limited to the fixed partition wall constituting the frame portion 51, but may be, for example, a sheet, a plate or the like which can be taken out of the module body. When a partition member made of a member that can be taken out is adopted, for example, the frame-shaped outer peripheral wall 37 itself described in the above embodiment functions as a frame portion. However, in terms of reduction in the number of parts and reduction in manufacturing cost, it is advantageous to adopt a configuration in which a fixed partition wall constituting the frame portion is used as a partition member and the entire frame portion is a single component integrally formed of resin. is there. The number of partition members is not limited to one, and a plurality of partition members may be provided in parallel inside the module main body to form three or more storage spaces. Also in this case, the workability in the storage spaces located at least at both ends can be improved by the configuration including the module main body that can be opened on both sides. As the optical fiber housed in the module body, the terminal is
The optical fiber 41 is not limited to the optical fiber 41 that is branched into a plurality of branched optical fibers 41b through the optical fiber. For example, the optical fiber 41 is not branched at all and is connected to an optical connector (such as the optical connector 40 which is an optical connector adapter).
