Connecting branch for submarine optical cable splitter

Abstract

The invention provides a connecting branch for a submarine optical cable splitter, and the connecting branch only comprises branch forks and branch fork rings; the structure is simple, the number of structural parts is small, and connection between the connecting branch and a rigid structure can be completed only by screwing the branch forks into the rigid structure through the thread structures; the branch cavities in the branch fork rings can be connected with the corresponding branch universal joints through the pins, so that the relative displacement between the branch cavities and the branch universal joints in the radial direction is prevented. Therefore, the connection operation between the connection branch and the rigid straight structure and the connection operation between the connection branch and the branch universal joint are simple and efficient. Meanwhile, the first branch part connected with the rigid structure in the branch fork adopts the circular radial section, the internal containing space of the branch fork can be effectively increased, the transition branch part and the third branch part are arranged between the first branch part and the second branch part in the branch fork, and the internal containing space of the branch fork can be further enlarged through the third branch part, so as to provide a larger space for the tail fiber.

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
