REINFORCING METHOD FOR SEALED CONNECTION PART OF OPTICAL FIBER CORE

摘要

PURPOSE:To easily form a high-reliability reinforcement part by sheathing optical fiber cores with a transparent plastic pipe around the sealed connection part of the optical fiber wires, and changing the gap with an adhesive from the injection hole of the pipe. CONSTITUTION:A transparent plastic pipe 1 is made of high-density polyethylene and a low-temperature plasma treatment is carried out. Optical fiber cores 3 are sheathed with a pipe 1 and optical fibers 4 and 4 are butted and connected by being sealed. The pipe 1 covers the optical fibers 4 and 4 around the connection part 6 including plastic coating layers 5 and 5, and an epoxy resin adhesive 2 is injected from an injection hole 7, and is heated and caked. Consequently, an increase in transmission loss resulting from fluctuations of temperature and the breaking of a fiber are reduced to constitute a reliable reinforcement part easily.
