Device for connecting submarine optical cable to land optical cable and connection method thereof

Abstract

The invention discloses a connecting device and a connecting method between a submarine optical cable and a land optical cable. The connecting device comprises a cover plate, a shell, a long screw, a fiber fusion tray, a cone seat and a land cable clamp. One side of the cover plate is a plane, and the other One side is provided with a circular concave area and a circular groove with the center as the origin, the shape of the shell matches the cover plate, a circular edge is provided at the open end of the shell, and a plurality of hollow cylinders are provided on the cylindrical surface, One of the hollow cylinders is fixedly connected to the submarine optical cable through the cone seat, and an inner cone and an outer cone are arranged between the submarine optical cable and the cone seat, and the other hollow cylinder is fixedly connected to the land optical cable through a land cable clamp; There are several splice trays, and the splice trays are fixed by long screws. The device can effectively clamp the armored steel wire, so that the submarine optical cable does not come out and does not break under the condition of severe tension; was pulled out.

Description

technical field [0001] The invention relates to a connection device and connection method between a submarine optical cable and a land optical cable, and is especially suitable for connecting a submarine optical cable with a land optical cable after landing, and also for connecting an underwater optical cable with a land optical cable. Background technique [0002] With the rapid development of my country's communication system, the use of the old submarine optical cable system has reached its end of life, and the construction and renewal of submarine optical cables have also increased. The submarine optical cable needs to be connected with the land optical cable after landing, and the safety and reliability of the connection device during use is very important. During the use of the submarine optical cable, the landing connection point will be subject to relatively large instantaneous tension from time to time. At the same time, due to the tide, the landing connection point...

AI Technical Summary

Problems solved by technology

During the use of the submarine optical cable, the landing connection point will be subjected to relatively large instantaneous tension from time to time. At the same time, due to the tide, the landing connection point will frequently cycle between wet and submerged states. If the connection point is not effectively protected, it will Causes the connection to be interrupted and the optical cable to be flooded, resulting in different losses
