Title:
FUSION SPLICING SYSTEM, FUSION SPLICING DEVICE, AND DETERIORATION DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/221115
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fusion splicing system, a fusion splicing device, and a deterioration determination method with which it is possible to determine a deteriorated state of electrodes with high accuracy. A fusion splicing system (10) of the present invention comprises: a fusion splicing device (1) including a first electrode (3c1) and a second electrode (3c2) for performing fusion splicing of optical fibers by electric discharge, and an electric discharge circuit (3d) for outputting a control signal (S1) to the first electrode (3c1) and receiving a feedback signal (S2) of the control signal from the second electrode (3c2); and a deterioration determination unit (22) for determining, from a state of the feedback signal (S2), whether or not the first electrode (3c1) and the second electrode (3c2) have deteriorated.
