Internal unit and tensioning method of a relay amplifier

Abstract

This application provides an internal unit of a repeater amplifier and a tensioning method. By improving the integration of the photoelectric drive unit and rationally arranging the photoelectric drive unit and the surge protection unit, it is possible to effectively reduce the load of the photoelectric drive unit on the disk fiber of the optical device. The space occupied in the circumferential direction of the box group and the space occupied by the surge protection unit in the cavity can be reduced, so that more space can be arranged for the optical device disk fiber box group, and the optical device disk fiber box group can be expanded. The volume of each optical device tray to accommodate more fiber pairs of optical devices. At the same time, since the tensioning mechanism and the tensioning spring have a simple structure and do not occupy the space of the optical device reel and fiber cassette in the cavity, it can also provide a structural basis for increasing the volume of the optical device reel and fiber cassette.

Description

technical field [0001] The present application relates to the technical field of submarine communication, in particular to an internal unit of a relay amplifier and a tensioning method. 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 schematic diagram of the structure of an existing submarine optical cable communication system is provided, such as figure 1 As shown, the existing first landing station computer room 100 on the shore, the existing second landing station computer room 200 and the existing third landing station computer room 300 transmit signals through submarine cables, wherein the existing first landing station computer room 100 outputs The signal is divided into two signals through the existing splitter 400 to be transmitted to the existing second landing station computer room 200 and the existing third landing station computer room 300 respectively....

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the structure of the internal unit of the existing relay amplifier, on the basis that the size of the cavity formed by the existing first casing 1001 and the existing second casing 1002 remains unchanged, due to the existing optical path unit 1004, the existing The three-layer ladder structure formed by the circuit unit 1005 and the existing surge protection unit 1006 will occupy the cavity in the y direction (such as image 3 shown), and because the existing tensioning mechanism 1007 has a certain width, the existing tensioning mechanism 1007 will occupy the cavity in the x direction (such as image 3 shown), thereby compressing the space that the existing optical device tray 1003 can occupy, and the smaller the existing optical device tray 1003, the less the number of optical devices that can be accommodated inside it, for example, one The existing optical device tray fiber box 1003 can only accommodate the number of optical devices of 2 fiber pairs, and the number of supported fiber pairs is small
