A submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body. The branch member is fixed to the device main body.

Submarine device, method of configuring submarine device, and submarine cable system

In an aspect of the present disclosure, a submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body.

A structure for introducing an optical cable into a communication apparatus includes an adapter (,) to be affixed to a side wall (,) forming a part of the casing (,) of the apparatus. A case (,) is fitted in a bore axially extending throughout the center of the adapter (,). A ring nut assembly (,) holds an optical cable (,) at its center and is connected to the adapter (,) in such a manner as to cover the case (,). The cable (,) includes a tension merber (,) introduced into the casing (,) via the case (,) and adapter (,) and affixed by a tension member affixing portion (,) disposed in the casing (,). In this condition, the cable (,) is firmly affixed by the ring nut assembly (,) and tension member affixing portion (,), i.e., at two points. The fibers of the cable (,) are therefore free from breakage ascribable to a twisting force or a pulling force.
