Abstract

PURPOSE:To reduce the size of an underwater branching device with simple structure by structuring two joint chambers to be arranged at one side of a pressure-tight cylinder so that one chamber is put in the other chamber. CONSTITUTION:One joint chamber 14 into which the optical fibers of a cable 11 are led is provided to one end part of the pressure-proof cylinder 10 and two joint chambers 15 and 16 into which optical fibers of two cables 12 and 13 are led are provided to the other end part to constitute the underwater branching device. Then, the two joint chambers at the other end part of the pressure-proof cylinder 10 are so structured that one cylindrical joint chamber 16 is put in the other cylindrical joint chamber 15.

Because the extra length of the optical fiber is processed in the joint chamber, a certain amount of outer diameter is required from the allowable bending radius of the optical fiber, and the two joint chambers are arranged in parallel. If the int chambers were simply arranged in parallel, the outer diameter of this part would be too thick, making it difficult to operate on board the laying ship, and the protruding parts could get caught on obstacles.
