Abstract: Disclosed is a theft sensing system for sensing a theft of a fusion splicer by using an information terminal. The system includes a wireless communication unit that enables the fusion splicer to perform wireless communication with the information terminal, an authentication processing unit that performs an authentication process such that the fusion splicer and the information terminal are wirelessly connected to each other, an acquisition unit that acquires wireless situation data between the fusion splicer and the information terminal which are wirelessly connected to each other, a decision unit that decides whether the fusion splicer moves in a direction away from the information terminal based on a change in the wireless situation data acquired by the acquisition unit, and a notification unit that performs a predetermined notification process in the information terminal when the decision unit decides that the fusion splicer moves in the direction away from the information terminal.

Abstract: A fusion splicer is disclosed. The fusion splicer includes a fusion splicing unit that fusion splices of optical fibers, a communication unit that communicates through wireless connection with an external terminal, and a setting unit that sets a fusion condition of the fusion splicing unit. The communication unit acquires information related to the fusion condition of the fusion splicing unit from the external terminal. The setting unit sets the fusion condition of the fusion splicing unit based on the acquired information related to the fusion condition. The fusion splicing unit fusion splices in accordance with the fusion condition set by the setting unit.

Abstract: A fusion splicer management system for managing progress of a fusion splicing work performed by each splicing technician by using a fusion splicer. This management system includes an acquisition unit, a determination unit, and a notification unit. The acquisition unit acquires fusion splicing data regarding the fusion splicing work performed by each splicing technician who uses each fusion splicer whenever each fusion splicing work is performed. The determination unit determines a progress status of each fusion splicing work by comparing the fusion splicing data with work plan data indicating a work plan. The notification unit notifies of the progress status of each fusion splicing work determined by the determination unit.

Abstract: A theft tracking system for tracking a stolen fusion splicer of fusion splicers each of which is wirelessly accessible.
