Abstract

The invention relates to an optical fiber composite low-voltage cable joint box and a connecting process thereof. The joint box is characterized by comprising a cable inlet hole module, a photoelectric connecting protection module and a cable outlet hole module, wherein the cable inlet hole module and the cable outlet hole module are symmetrical to each other relative to the photoelectric connecting protection module and are connected with the photoelectric connecting protection module through screw threads respectively; and the outer diameter of the photoelectric connecting protection module at a screw thread joint is smaller than those of the cable inlet hole module and the cable outlet hole module. The connecting process comprises the following steps that: an optical fiber enters from a branching hole; the optical fiber enters an optical fiber connecting distribution channel in a spiral or sinusoidal way; and joints are fixed in the optical fiber connecting distribution channel and are connected. The equipment has the characteristics of assembly and disassembly flexibility and convenience of maintaining, is convenient to install, disassemble and assemble, do not need integral replacing during breakdown maintenance and saves maintenance cost.

Description

technical field [0001] The invention relates to an optical cable, in particular to an optical fiber composite low-voltage cable joint box and its connection. Background technique [0002] Optical fiber composite low-voltage cable (OPLC) is a composite cable that integrates optical fiber and power transmission copper wire that has gradually emerged in recent years. It has the characteristics of high broadband and high reliability data transmission, and at the same time solves the problems of power consumption and optical signal transmission in the community. , not only retains the characteristics of ordinary optical fiber cables, but also meets the requirements of low-voltage transmission cables, and is very suitable as a transmission medium to build access networks. The use of photoelectric composite cables to realize power fiber-to-the-home can vigorously promote the work process of "three-network integration" of voice, data and TV. [0003] With the steady advancement of ...
