Abstract

The invention discloses a submarine optical cable system for raising the application depth of a splitter, comprising: an underwater splitter, a trunk submarine cable, a branch submarine cable, a splitter recovery reinforcing cable, a first joint box, a second joint box and a third joint box, the first joint box is set between the front end of the trunk submarine cable and the tail end of the diverter recovery strengthening cable, the trunk end of the underwater branch is provided with a first tail cable, and the second joint box is set at the branch between the front end of the reinforcement cable recovered by the device and the tail end of the first tail cable, the branch ends of the underwater branch are respectively provided with second tail cables, and the third joint boxes are respectively connected to the front ends of the second tail cables and the corresponding between the ends of branch submarine cables. Through the above method, the lifting splitter of the present invention is applied to the deep submarine optical cable system, and the high NTTS force value and low water weight characteristics of the reinforced cable are used to recover the splitter to realize the application and recyclability of the underwater splitter exceeding 7,000 meters in water depth. , without reducing the reliability of the system.

Description

technical field [0001] The invention relates to the field of submarine optical cable systems, in particular to a submarine optical cable system with a water depth lifting device applied. Background technique [0002] The submarine optical cable system is mainly used in transoceanic communication, marine resource development, coastal defense construction and other fields, and 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 and RPT underwater. Repeater, BU underwater splitter, OEQ optical power equalizer and JB connector box. Among them, the underwater splitter is mainly used for the photoelectric merging and splitting between the three sections of submarine optical c...
