Claims

[Scope of Claim for Utility Model Registration] (1) An optical fiber excess length holding means is provided at each of the connection ends of the first and second optical fiber cables to be connected, and the optical fiber excess length is held. The means are
a substrate, and a plurality of optical fiber core extra length holding members provided on the substrate on substantially the same circumference to hold the extra length portions of each of the optical fiber connection ends in a substantially circular loop; The optical fiber excess length holding member is formed so that its cross-sectional shape is roughly C-shaped with a notch in a part, and the optical fiber excess length at each optical fiber connection end is The optical fiber is inserted into the optical fiber excess length holding member and held in the open position with the notch facing outward, and the optical fiber inserted and held within the optical fiber excess length holding member. The cutout portion is swingably attached to the substrate so as to be able to swing between a closed position facing the substrate and a closed position facing the substrate in order to accommodate and hold the excess core length portion in cooperation with the substrate. An optical fiber cable connecting portion surplus length retaining device. (2) Utility model registration claim No. 1 in which the optical fiber core extra length holding member is formed integrally with the substrate.
Apparatus described in section. (3) The device according to claim 1, wherein the optical fiber excess length holding member is attached to the substrate by a hinge member. (4) The device according to claim 1, 2, or 3 of the utility model registration, wherein an elastic material is disposed on the inner surface of the optical fiber excess length holding member having a C-shaped cross section.
