Optical Fiber Coating Process

Abstract

The invention discloses an optical fiber coating technology which is characterized in that a low-cost silicon material fixing plate is adopted to clamp optical fibers, and tin foil or aluminum foil is used to protect areas which are not required to be coated on the optical fibers, so that the original common optical fiber coating machine not for optical fiber coating can be used for the optical fiber coating finally. The optical fiber coating technology has the benefits that the common optical fiber coating machine can accomplish partial coating treatment on the optical fibers; no high-cost special fixture or special precise optical fiber coating equipment is required to be purchased; the production cost is lowered; as the fixing plate is made of a silicon material, the fixing plate is low in cost and reusable; and the optical fiber coating technology is easy and simple to operate.

Description

technical field [0001] The invention relates to an optical fiber coating technology, in particular to an optical fiber coating process. Background technique [0002] With the rapid development of many fields such as fiber optic coupling, optical signal transmission, and fiber optic sensing, problems such as how to effectively reduce the loss of fiber optic connectors and improve coupling efficiency have emerged while the amount of optical fibers is increasing rapidly; some signal detection or transmission applications require The optical fiber has a certain light reflection ability. In order to make the optical fiber have the light reflection ability, the conventional method is to coat the surface of the optical fiber. The industry has conducted many years of research on the coating process. The current coating methods mainly include: 1. Using special fixtures and special precision Optical fiber coating equipment for coating; 2. Optical fiber chemical plating; 3. Solution pu...

AI Technical Summary

Problems solved by technology

Among them, in the method described in item 1, the price of the special fixture and the special precision optical fiber coating equipment are very high, and the cost is huge, and the special fixture is relatively precise, difficult to clean, and easy to damage; electroless plating and solution pulling method require special equipment, Restricted by the type of film layer, the type of film layer that can be coated is single and the coating process is cumbersome, it is difficult to achieve precise control of film thickness, and the processing efficiency is very low, it is difficult to meet the requirements of mass production

[0003] The existing ordinary optical coating machine has many types of coating, low equipment cost and simple operation, but due to the lack of corresponding fixtures, it cannot be directly used to coat optical fibers, especially for partial coating of optical fibers
