た。 Extra length core lines 5a, 5b to this extra length processing sheet 1
The optical fiber connecting portion 6 is inserted from both sides of the side edge 7a, or from either side of the side edge 7a with a large vertical distance between the excess length processing sheet 1 and the left side edge 7a. However, in the case of one-way storage, it is necessary to open the extra length processing sheet 1 widely in the vertical direction, so the optical fiber core 4 above the storage position is stretched, so that the excess length processing sheet 1 is There was a possibility that the curvature of the extra length core wires 5a, 5b could not be maintained, resulting in increased optical loss. Furthermore, in one-way storage, if you want to store the extra length fibers from the storage side to the opposite side edge, arrange the extra length fibers in a circle outside the excess length processing sheet on the storage side, and In order to store the fiber cable connection part on the side surface 7b of the opposite side edge, after storing the extra length of the cable,
A large amount of slack occurs in the optical fiber core between the optical cable and the extra length processing sheet, and an additional work is required to feed this slack into the extra length processing sheet.

The fiber storage sheet 1 is placed in a storage portion defined between the flat portion and a flexible protrusion 11 provided on the flat portion of the extra length fiber storage sheet 9.
The core wires are housed so that the joint portions 13 of the two are sandwiched between them to make the arrangement of the core wires uniform. Since the fibers are restrained and arranged by the fiber storage sheet 12 in this way, individual storage becomes possible. Furthermore, as shown in FIG. 2, when stacked in the vertical direction, the arrangement of the core wires in the vertical direction is also uniform, so unlike the conventional example, the compression of the core wires due to compression from above becomes uniform. "Dispersion" in loss increases can be suppressed. Further, since the extra length core wire 5 and the optical fiber core wire connecting portion 6 are stored in one direction from the side edge 9a side of the bent shape, it is easy to secure a storage space in a manhole or the like.

易になる利点がある。(Effects of the invention) As explained above, according to the invention, by restraining the optical fiber connecting portion and the extra length core wire arranged in a circular or elliptical shape with a fiber processing sheet, Individual storage is possible. Furthermore, a cut slit is formed in the flat part of the excess fiber storage sheet to provide a flexible protrusion, and the joint part of the fiber processing sheet is placed in the storage area defined between the protrusion and the flat part. By storing the fibers in a sandwiched manner, the arrangement of the fibers becomes uniform, and even when the extra-length fiber storage sheets are stacked in the vertical direction, the vertical arrangement becomes uniform. Therefore, the pressure on the core wire due to compression from above becomes uniform,
“Dispersion” in loss increases can be suppressed. In addition, since the extra-length fiber processing sheet is fixed at a bent part on one side, the optical fiber connection part and the extra-length fiber core restrained by the fiber processing sheet can be stored in one direction, so that it can be stored in one direction, such as in a manhole. This has the advantage of making it easier to secure work space.
