Optical fiber connection part

Abstract

Abstract PURPOSE:To improve the strength of a connection part by butting and connecting end surfaces of optical fiber which have plastic coatings removed, forming a metallic coating around the connection part, and further covering the external circumference with synthetic resin. CONSTITUTION:Optical fibers 2 which have plastic coating layers 1 removed and then have end surfaces 3 sealed together are inserted into retainers 8 on both sides of a bell jar 7, which is sealed hermetically through sealing materials 9. Glow discharge is caused between a target 10 and an anode 11 to form a metallic film 5 around the connection part 4. Both the retainers 8 are rotated to coat the overall external circumference of the optical fibers 2 with the metallic coating, and the external circumference of the coating is further covered with synthetic resin. The metallic film 5 reinforces the optical fibers 2, increasing the strength of the connection part 4.
