System and method for providing underwater communication data

摘要

A system and a method for communication in a submarine communication network are disclosed. The communication system comprises a branching unit, an optical cable segment comprising a first conductor path and a second conductor path, a repeater and an insulation and loopback circuit. The branching unit is configured for enabling exchange of optical communication data and electric power between an optical trunk cable of the submarine communication network and the cable segment. The insulation and loopback circuit is configured to receive the optical communication data and the electric power through said first conductor path, direct at least a part of said electric power back to the trunk cable through said second conductor path and the branching unit, and direct said optical communication data to a remote platform through a third conductor path.
