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

A method of configuring a submarine device comprising:

• branching a main tail cable connected to a submarine cable into a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable and a second branch tail cable including a second group of optical fibers among the plurality of optical fibers through a branch member;
• introducing the first branch tail cable into a device main body through a first introduction part and introducing the second branch tail cable into the device main body through a second introduction part;
• and
• fixing the branch member to the device main body.

A submarine cable system comprising:

• a submarine cable;
• and
• a submarine device connected to the submarine cable, wherein
• the submarine device comprises:
• 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 configured to couple 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, and
• the branch member is fixed to the device main body.
