    摘要: An apparatus includes a weld coupling and a thermal insulator. The weld coupling is adapted to be welded to an outer housing of a first cable segment to couple the first cable segment to a second cable segment. The thermal insulator is adapted to prevent thermal damage to a communication line of the first cable segment when the weld coupling is welded to the outer housing.
