Claims

[Scope of utility model registration request]

In a structure for electrically and optically connecting a submarine optical cable to a submarine optical repeater, the tail cable connection portion of the submarine optical cable includes a metal pressure-resistant pipe electrically connected to a power supply line of the submarine optical cable; A tail cable consisting of a plurality of optical fibers housed in the pressure-resistant pipe and connected to the optical fibers of the submarine optical cable, and a polyethylene coating covering the outside of the pressure-resistant pipe is provided, and a tail cable connection portion of the submarine optical repeater is provided. includes a metal pressure-resistant pipe that is electrically connected to the power supply line of the submarine optical repeater, and a metal pressure-resistant pipe that is housed in the pressure-resistant pipe and that is optically connected to the submarine optical repeater.
A tail cable consisting of a plurality of optical fibers connected to the pipe and a polyethylene coating covering the outside of the pressure-resistant pipe is provided, and these two tail cables are electrically and optically connected via a joint chamber, The joint chamber is electrically connected to each tail cable, and includes a pair of pressure-resistant metal shells that are fixed against each other, and covers the outside of the pair of pressure-resistant metal shells, and is connected to each tail cable. The connecting portion and the extra length of the optical fibers of each tail cable are housed in a pressure-resistant watertight space formed between the abutting surfaces of the pair of pressure-resistant metal shells, which is composed of a polyethylene outer sheath that is continuous with a polyethylene outer sheath. A connection structure between a submarine optical repeater and a submarine optical cable.
