Fiber fusion splicer and fiber tail end surface processing method

Abstract

The invention discloses a fiber fusion splicer and a fiber tail end surface processing method. The method comprises main steps: the flatly-cut fiber tail end surface is pushed to the range of arc flame generated by an electrode rod through a pushing mechanism, the electrode rod then generates the arc flame lasting for a certain time duration to carry out smooth processing on the fiber tail end surface, the processing effects are monitored through a microscope and an image sensor, the fiber tail end surface processed by the method is used for cold welding, and the echo loss and the insertion loss are greatly optimized.

Description

technical field [0001] The invention relates to the field of an optical fiber fusion splicer, in particular to an optical fiber fusion splicer and a method for processing the end face of an optical fiber. Background technique [0002] In the construction of optical fiber communication, there are two commonly used splicing methods for optical fibers: hot splicing and cold splicing. [0003] The thermal splicing method is also called the fusion splicing method, which refers to the permanent splicing of two sections of optical fibers using an optical fiber fusion splicing machine as a special tool. [0004] The cold splicing method is to mechanically process the end faces of the two sections of optical fibers and then use a mechanical fixing device to fix the two sections of optical fibers in an aligned state. The fixing devices are divided into two types: pluggable connectors and fixed cold splices. kind. [0005] No matter which splicing method is used, the optical fiber wi...

AI Technical Summary

Problems solved by technology

[0008] To sum up, the existing optical fiber cold splicing technology has disadvantages: 1. If there is no condition to grind the end face of the optical fiber obtained by mechanical cutting, it will produce too large insertion loss and too small return loss after splicing, resulting in Light transmission loss is more serious

2. If there are construction requirements for optical fiber fusion splicing and optical fiber cold splicing at the same time, a lot of equipment needs to be carried, and the volume and weight of the equipment are large, which increases the burden of carrying, wastes manpower and increases costs
