の開発が要求されている。本考案はこの要求に基
づいて案出されたものである。 In optical communications, when laying optical submarine cables over long distances, optical submarine repeaters are required along the way. In this case, if the structure of the conventional coaxial cable type analog submarine repeater unit is followed as it is, there will be a limit to the bending radius of the optical fiber, which will cause problems in its wiring. Figures 1 and 2 show a conventional analog submarine repeater unit, which is shaped like a round cylinder with each circuit unit 1 for power separation, amplification, etc.
-1 to 1 -o are connected by a mounting bar 2 and housed in a cylindrical housing 3, and the wiring between each circuit unit is connected by a coaxial cord 5 in the gap 4 between the housing 3 and each circuit unit. I'm doing it by letting it crawl. Therefore, when this structure is adopted for an optical submarine repeater unit, the gap 4 between the cylindrical circuit unit 1 and the cylindrical case 3 is narrow, so the optical fiber coming out of the circuit unit is routed in the gap 4. This is difficult to implement because the optical fiber requires a certain bend radius. Therefore, there is a need to develop a structure suitable for optical submarine repeater units. The present invention was devised based on this requirement.

底を兼ねることを特徴とするものである。 Therefore, in the optical submarine repeater unit of the present invention, a plate having a width approximately equal to the inner diameter of the housing and an H-shaped cross section is inserted and fixed into the cylindrical housing.
A circuit unit is mounted on the surface of the H-shaped plate, the lid of the circuit unit is of a sliding type, and the lid of the circuit unit directly mounted on the H-shaped plate is further mounted on the circuit unit. It is characterized in that it also serves as the bottom of the circuit unit.

To explain the figure, numeral 3 is a cylindrical housing, 6
is an H-shaped plate which is the key point of the present invention, and its width is made approximately equal to the inner diameter of the housing 3, and is inserted and fixed into the housing. Circuit units 7 -1 to 7 -o are attached to this H-shaped plate 6. In the figure, the circuit units 7, 7' are attached to both the front and back sides of the H-shaped plate 6, but they may be attached to only one side. The circuit units 7, 7' have a rectangular cross section as shown in the perspective view of FIG. 5, and their upper covers 8, 8' are of a sliding type and can be opened and closed in the directions of the arrows. Also, symbols 9 and 9' are printed wiring boards of circuit units;
Reference numeral 10 denotes an optical component mounted thereon, and an optical fiber 11 connected to the optical component 10 comes out from the side of the circuit units 7, 7' and connects the circuit units 7, 7'.
7' and a cylindrical housing 3 (not shown).

Its assembly and test adjustment are also extremely easy. Further, since the optical fiber 11 is wired in a sufficiently wide space formed between the cylindrical housing 3 and the circuit units 7, 7' having a rectangular cross section, a sufficient bending radius can be achieved. Furthermore, when performing maintenance or adjustment of each circuit unit 7, 7', the H-shaped plate 6 can be pulled out from the housing 3 and the lid of the circuit unit 7, 7' can be opened by sliding it. Adjustment becomes extremely easy.
