A broken fiber self-repairing optical fiber and a broken fiber repairing method

Abstract

The invention relates to a broken fiber self-repairing optical fiber and a broken fiber repairing method. The self-repairing optical fiber includes a core and a cladding, and the cladding is made of polyether thiourea glass material. When repairing the broken fiber of the optical fiber, the fracture surface of the two sections of optical fiber is first cut flat with an optical fiber cutter; Contact each other; apply relative pressure to the two sections of optical fiber for 20 seconds, so that the polyetherthiourea glass material cladding of the two sections of optical fiber is bonded to each other; take out the bonded optical fiber from the fiber optic connector, and heat shrink The tube is moved to the section repair position, and the heat-shrinkable tube is heated so that the heat-shrinkable tube wraps the optical fiber. The broken fiber self-repairing optical fiber and the broken fiber repairing method can achieve the effect of hot splicing by using a method similar to cold splicing, the splicing loss is small, no matching liquid is needed, and the quality is stable and reliable.

Description

technical field [0001] The invention relates to a broken fiber self-repairing optical fiber and a broken fiber repairing method, belonging to the technical field of optical fiber manufacturing. Background technique [0002] Traditional optical fiber splicing can generally be divided into two categories: cold splicing and hot splicing of optical fibers. Optical fiber cold splicing does not require too much equipment, just a fiber cutter. Each joint needs a quick connector, which is easy to operate and suitable for field work. However, when using cold splices, quick connectors, etc. for cold splicing operations, Because the optical fiber matching fluid is used in cold splices and quick connectors, after one to two years of environmental aging, the matching fluid will gradually decrease, and the splicing loss will gradually increase from 0.3dB to 0.5dB or more, affecting the use of link communication. [0003] Optical fiber thermal splicing method. It is necessary to prepare ...

AI Technical Summary

Problems solved by technology

It is necessary to prepare expensive and heavy fusion splicers and optical fiber cutters. At the same time, a flat and clean work table and a clean environment are required. Stable power supply functions are also required for long-term operations, but the cost of equipment in this way is too high. Power storage capacity is limited, and field operations are restricted
