Production method for overlapping and cladding twin-core plastic optical fibers

Abstract

The invention provides a production method for overlapping and cladding twin-core plastic optical fibers. The production method includes the steps of pre-treating feed materials, wherein raw materials and hoppers of extruding machines are dried; carrying out plastification through the extruding machines, wherein core materials are added into the core material extruding machine for heating plastification, the core material extruding machine is provided with a plurality of core material heating areas with the temperature gradually increased, and skin materials are added into the skin material extruding machine for heating plastification; carrying out formation through molds, wherein the plastified core materials and the plastified skin materials are guided into the molds and divided into multiple strands of core materials and multiple strands of skin materials respectively, then the multiple strands of core materials and the multiple strands of skin materials enter multiple-hole mold heads for being separated, and then multiple plastic optical fibers are formed; carrying out secondary plastification, wherein the plastic optical fibers undergo secondary heating plastification; carrying gradual cooling treatment, wherein the plastic optical fibers undergo gradual cooling treatment; carrying out pattern fixing and drawing, wherein the plastic optical fibers are drawn by a drawing machine; and carrying out taking-up, wherein the plastic optical fibers are taken up and packaged by a plurality of taking-up reels. According to the production method, the production efficiency is greatly improved, the product quality is improved, and the market value is high.

Description

technical field [0001] The invention relates to the field of light guide elements, in particular to a production method for overlapping and cladding double-core plastic optical fibers. Background technique [0002] Plastic optical fiber (POF) is made of high transparent polymers such as polystyrene (PS), polymethyl methacrylate (PMMA), polycarbonate (PC) as the core material, and PMMA, fluoroplastic, etc. as the skin material. Optical fiber (optical fiber). Different materials have different light attenuation properties and temperature application ranges. Features. Plastic optical fiber can not only be used in the last 100-1000 meters of the access network, but also can be used in various vehicles, aircrafts and other vehicles. It is an excellent short-distance data transmission medium. [0003] Plastic optical fiber has the advantages of large communication capacity, strong anti-electromagnetic interference, superior confidentiality, light weight, high speed, high fideli...
