Abstract

The purpose of the present invention is to provide a method and device which can discriminate all kinds of the optical fibers and carry out the melting-connection using the connection conditions suitable to the various optical fibers. The present invention is the melting-connection device which melt-connects through the discharge by pressing near the end portion of the optical fiber, and it is provided with: the image observation mechanism (1) which observes the end portion of the optical fiber; the image treatment department (2), which measures the parameter data of the illumination distribution waveform of the optical fiber cross section based on the image taken; the fuzzy-calculation-department (4) which identifies the optical fiber categories through the correlations obtained by fuzzy-calculating the fuzzy-calculation data by registering the measured parameter data in the registration department (3) in advance; the cross-reference department (6) which cross-references the identified optical fiber category to the optical fiber category melting-conditions registered in the melting-connection-condition-registration-department (5) prepared in advance; the display device (7) which displays the results of the cross-references; the melting-connection mechanism (9); and the control department (8).

Description

field of invention [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 of the invention [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 splice...
