Abstract

An object of the invention is to provide an apparatus and method for fusing optical fibers under fusion splicing conditions suitable for various optical fibers, in which the types of optical fibers can be sufficiently identified. The present invention provides a device for welding the ends of optical fibers by butt discharge, the device includes an image observation mechanism (1) for observing the ends of optical fibers; an image processing part (2) for picking up The parameter data of the luminance distribution waveform in the cross-section of the image measurement optical fiber; a fuzzy operation part (4), which is used to obtain the degree of attribution of the measured parameter data from the fuzzy operation data pre-recorded in the data recording part (3), and Identify the type of optical fiber by fuzzy operation; a proofreading part (6), for utilizing the splicing conditions of each type of optical fiber pre-recorded in the splicing condition recording part (5), proofreading the type of identified optical fiber; a display unit ( 7), for displaying the proofreading result; a welding mechanism (9), and a control part (8).

Description

technical field [0001] The present invention relates to an apparatus and method for fusing the ends of communication optical fibers by electric discharge heating or the like, and more particularly to an apparatus and method for fusing optical fibers under fusion splicing conditions suitable for the type of optical fiber by automatically determining the type of optical fiber. method. Background technique [0002] In recent years, with the expansion and diversification of optical fiber communication, various types of optical fibers for various purposes have been developed and utilized. Various types of optical fiber are available, including single-mode optical fiber (hereinafter referred to as SM optical fiber), multimode optical fiber (hereinafter referred to as MM optical fiber), dispersion-shifted optical fiber (hereinafter referred to as DS optical fiber), and erbium-doped optical fiber (hereinafter referred to as ED fiber). When these optical fibers are spliced ​​using ...
