Problems solved by technology

[0009] Ribbon optical fibers are currently torn directly by hand one by one. Because the optical fibers are particularly thin and brittle, they are relatively easy to tear, and the speed is very slow, which takes up a lot of labor.

Abstract

The invention relates to optical fiber stripping solution and a preparation method thereof, and an optical fiber stripping method. The optical fiber stripping solution comprises chloroform, formic acid, acetophenone, paraffin, benzoic acid and a thickener. The optical fiber stripping method comprises the following steps of: heating the optical fiber stripping solution to 40 to 50 DEG C, soaking astrip optical fiber needing to be stripped in the optical fiber stripping solution for 2 to 3 seconds, taking out, waiting for 2 to 4 seconds for full reaction, and cleaning the optical fiber to remove an encapsulating layer. By the method, the encapsulating layer of the optical fiber can be quickly removed, the optical fiber is completely stripped, and a fiber core, a cover layer and a coating layer are not damaged, so that the optical fiber is prevented from being broken or damaged in the stripping process; and compared with the conventional manual stripping process, the method improves thespeed by 30 times, saves a large amount of labor and improves production efficiency.

Description

technical field [0001] The invention relates to a method for stripping optical fibers, a stripping liquid for stripping optical fibers and a preparation method thereof. Background technique [0002] The structure of ribbon optical fiber can be roughly divided into encapsulation layer and optical fiber. [0003] The encapsulation layer mainly uses polymer resin such as polyethylene or polyester. Its function is to wrap several optical fibers, and stack the optical fibers in a regular parallel arrangement to form a ribbon. [0004] The structure of optical fiber is divided into core, cladding and coating from inside to outside. [0005] Fiber core, the material used is SiO 2 -- GeO 2 , the role is to transmit light. [0006] Cladding, the material is mostly SiO 2 —B 2 o 3 or SiO 2 —P 2 o 5 , the role is to constrain the light. [0007] The coating layer is a polymer material layer coated to protect the bare optical fiber, improve the mechanical strength and microben...
