Submarine optical cable system for improving application water depth of splitter

Abstract

The invention discloses a submarine optical cable system for improving the application water depth of a splitter, and the system comprises an underwater splitter, a main submarine cable, a branch submarine cable, a splitter recovery reinforcement cable, a first connector box, a second connector box, and a third connector box, and the first connector box is disposed between the front end of the main submarine cable and the tail end of the splitter recovery reinforcement cable. The main end of the underwater splitter is provided with a first tail cable, the second connector box is arranged between the front end of the splitter recovery reinforcing cable and the tail end of the first tail cable, the branch ends of the underwater splitter are respectively provided with a second tail cable, and the third connector boxes are respectively connected between the front ends of the second tail cables and the tail ends of the corresponding branch submarine cables. According to the submarine optical cable system for improving the application water depth of the splitter, the characteristics of high NTTS force value and low water weight of the splitter recovery reinforced cable are utilized, application and recoverability of the underwater splitter at the water depth exceeding 7000 meters are achieved, and the reliability of the system is not reduced.

Description

technical field [0001] The invention relates to the field of submarine optical cable systems, in particular to a submarine optical cable system for raising the application water depth of a splitter. Background technique [0002] The submarine optical cable system is mainly used in fields such as transoceanic communication, marine resource development, and coastal defense construction, which is of great significance. The submarine optical cable system is generally composed of shore-based dry-end equipment and underwater wet-end equipment. The dry-end equipment mainly includes SLTE shore-based transmission, PFE remote power supply and SLM submarine optical cable system monitoring. The wet-end equipment mainly includes SOFC submarine optical cable, RPT underwater Repeater, BU underwater splitter, OEQ optical power equalizer and JB splice box. Among them, the underwater splitter is mainly used for the merging and splitting of photoelectricity between the three sections of subma...

Problems solved by technology

[0005] In order to increase the recoverable water depth of the branch, an existing solution is to cut off a branch leg during recovery to release the full water weight of the branch cable, but this solution is complicated to operate, has low reliability, and even endangers the entire seabed Performance of fiber optic cable system
