Non-reflection optical fiber termination and method of manufacturing the same

Abstract

An optical fiber 2 is spliced to an optical fiber 1 in a state that those optical fibers are axially shifted away from each other by an offset quantity D. With this splicing of the optical fibers, a coupling loss arises at a fusion splicing part 1c. A plurality of fusion splicing parts 1c are provided. The terminal part of the final optical fiber of serially spliced optical fibers is a non-reflection treating part 10. Light propagating through the optical fiber 1 is attenuated at the fusion splicing part, whereby non-reflection of light is realized. The back reflection light is also attenuated at the fusion splicing part, thereby reducing the amount of the back reflection light traveling back to the core 1a of the optical fiber 1.
