Anti-corrosion flexible optical cable and preparation method thereof

Abstract

The invention discloses an anti-corrosion flexible optical cable and preparation method thereof. The anti-corrosion flexible optical cable includes six layers, i.e., a surface layer, a reinforced anti-corrosion layer, a middle layer sleeve, a shielding layer, an inner cladding layer and a core material, the surface layer is made of a mixed material of epoxy resin and glass fibers according to theweight ratio of 9:1, the reinforced anti-corrosion layer is woven by alumina ceramic fibers, the middle sleeve is made of black silicone rubber, the shielding layer is a carbon film, the inner cladding layer is silica-based low-refractive index glass, and the core material is silica-based high-refractive index glass. The silica-based low-refractive index glass comprises, by molecular quantity, 85-92 parts of silica, 2-3 parts of sulfur dioxide, 2-3 parts of carbon dioxide and 6-8 parts of boron oxide. The silica-based high-refractive index glass comprises, by molecular quantity, 85-92 parts ofsilica, 3-4 parts of phosphoric anhydride and 8-10 parts of germanium oxide. The anti-corrosion flexible optical cable is high in insulation performance, good in shielding effect, small in minimum bending radius, resistant to high temperature and aging and long in service life.

Description

technical field [0001] The invention relates to the field of optical elements, in particular to a corrosion-resistant flexible optical cable and a preparation method thereof. Background technique [0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. cable assembly. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That ...
