Abstract

The invention provides a method for manufacturing an optical fiber positioning groove of a substrate used for optical fiber communication by a mould pressing process. The method uses a template of which a lateral surface is provided with a positioning groove mould having the same shape as the positioning groove. The method comprises: a step of uniformly coating a layer of film on the surface of the substrate, wherein the thickness of the film is greater than the depth of the positioning groove; and a step of coating a layer of release agent on the surface of the positioning groove mould of the template. The technical scheme of the invention is adopted, so the manufacturing is simple, the operation is convenient, the cost is low, the production speed is high and batch production can be realized.

Description

technical field [0001] The invention relates to a manufacturing method of a base plate with a V-groove for optical fiber positioning for optical fiber. Background technique [0002] In recent years, with the increase in demand for multi-fiber high-density connectors and the improvement of connector butt joint accuracy in fiber-to-the-home planar waveguide splitters and parallel optical connection systems, traditional single-channel connectors or low-channel connectors have been unable to meet the needs of the existing market. requirements. At present, the production of substrates with V-shaped grooves mainly includes three methods: mold opening method, precision machining method and etching method. [0003] The cost of ultra-high-precision mold manufacturing is very high, and the mold has a certain service life. When the number of V-groove channels is greater than 24, the machining accuracy cannot meet the requirements. [0004] The cost of using high-precision machining m...
