Mini optical branching module

Abstract

The invention relates to a mini optical branching module. The mini optical branching module comprises an input end connecting assembly, a shunt assembly, a metal pipe with openings at two ends, and anoutput end connecting assembly comprising at least two paths of outputs; and the shunt assembly is packaged in the metal pipe. The input end of the shunt assembly extends out of the front end of themetal pipe, then extends into the rear end of the input end connecting assembly and extends out of the front end of the input end connecting assembly, and the output end of the shunt assembly extendsout of the rear end of the metal pipe, then extends into the front end of the output end connecting assembly and extends out of the rear end of the output end connecting assembly. According to the invention, received light is divided into multiple paths through the shunt assembly arranged in the metal pipe, and, meanwhile, the shunt assembly is coupled with the input end connecting assembly and the output end connecting assembly, the size of the whole optical branching module is greatly reduced, messy wiring caused by independent wiring is avoided, the size of the whole optical branching module is small, the position of a distribution box does not need to be independently arranged in advance, the requirements of users for multiple optical fiber interfaces can be met, and installation and debugging are convenient.

Description

Technical field [0001] The present invention relates to the field of optical communication technology, in particular to a mini optical branching module. Background technique [0002] Optical Distribution Network (ODN) is based on passive optical network technology, which provides optical transmission channels between optical line terminals (OLT) and optical network units (ONU) through optical splitters. In fiber-to-the-home systems, optical splitters have become a solution adopted by various operators. In actual use, the optical splitter is mainly installed in the corridor, and installed in the wiring box by inserting a box and a rack. [0003] There are two practical problems with the above: [0004] 1. The wiring box is placed in the corridor, which is not beautiful; [0005] 2. Large size; [0006] 3. The wiring is messy. [0007] In addition, when a new telecommunications provider enters the fiber-to-the-home scenario, there is no place for the distribution box to be reserved for ...

AI Technical Summary

Problems solved by technology

[0004] 1. The wiring box is placed in the corridor, which is not beautiful;

[0005] 2. Large size;

[0006] 3. Messy wiring

[0007] In addition, when a new telecom provider enters the fiber-to-the-home scenario, there is no reserved space for a distribution box for the new provider, or when an individual user needs two fiber optic interfaces due to a large living area, there are only inserts on the market. Optical splitters packaged in boxes, racks, etc.
