A fusion splicing system according to one embodiment includes: first and second electrodes that fusion-splice optical fibers by discharge; a fusion splicing device that has a discharge circuit that outputs a control signal to the first electrode and receives a feedback signal of the control signal from the second electrode; and a deterioration determination unit that determines from a state of the feedback signal whether or not the first electrode and the second electrode are deteriorated.

Fusion splicing system, fusion splicing device, and deterioration determination method

A management system of a fusion splicer for selecting an appropriate maintenance base when the fusion splicer malfunctions. The management system includes a determination unit configured to determine a type of a failure mode of the fusion splicer, an acquisition unit configured to acquire position information of the fusion splicer, and a selection unit configured to select an appropriate maintenance base on the basis of the type of the failure mode determined by the determination unit and the position information of the fusion splicer acquired by the acquisition unit.

Fusion splicing apparatus management system and fusion splicing apparatus management method

A system for releasing locking of a fusion splicer includes a fusion splicer, an information terminal, and a server. The fusion splicer locks a fusion-splicing function in accordance with a predetermined lock condition and releases the locked function in accordance with a release command input. The server includes a storage unit that stores authentication information provided by a user of the fusion splicer, a collation unit that collates authentication information provided from the information terminal with the authentication information stored in the storage unit, and a password issuance unit that issues a one-time password including at least a date in an algorithm when a collation result is favorable. The information terminal authenticates the one-time password in consideration of a day difference or a time difference between the information terminal and the server and applies the release command to the fusion splicer when an authentication result is favorable.
