A connection branch for a submarine optical cable splitter

Abstract

The present application provides a connection branch for a submarine optical cable splitter. The connection branch only includes two parts, a branch fork and a branch fork ring. The connection between the connecting branch and the rigid structure can be completed, and the connection between the branch cavity in the branch fork ring and the corresponding branch universal joint can be completed through the pin, so as to prevent the radial direction between the branch cavity and the branch universal joint. relative displacement. It can be seen that the connection operation between the connection branch and the rigid structure and the branch universal joint is simple and efficient. At the same time, the first branch connected to the rigid structure in the branch fork adopts a circular radial section, which can effectively increase the internal accommodation space of the branch fork, and the branch fork is between the first branch and the second branch A third section of the transition section is provided, through which the internal accommodation space of the branch fork can be further enlarged to provide more space for the pigtail.

Description

technical field [0001] The present application relates to the technical field of submarine communication, in particular to a connection branch for a submarine optical cable splitter. Background technique [0002] Submarine cable (undersea cable) is a cable laid on the seabed for the transmission of optical signals on the seabed. figure 1 A structural schematic diagram of a submarine optical cable communication system is provided, such as figure 1 As shown, signals are transmitted between the first landing station computer room 01, the second landing station computer room 02 and the third landing station computer room 03 on the shore through submarine cables, wherein the signal output by the first landing station computer room 01 is divided into The two signals are transmitted to the second landing station computer room 02 and the third landing station computer room 03 respectively, wherein the signals are amplified by the amplifier 05 to ensure the transmission quality of t...

AI Technical Summary

Problems solved by technology

It can be seen that the structure of the existing connection branch 002 is relatively complicated, and the connection between the rigid structure and the branch universal joint can only be realized through the precise cooperation between multiple parts, the production cost is high, and the assembly process is relatively complicated, especially Difficult to adapt to underwater assembly
