Fusion condition providing system

A fusion condition providing system for an optical fiber fusion splicer includes: a storage device storing a database of fusion conditions; a user-side communication unit transmitting a command for requesting a fusion condition for a pair of optical fibers to be fusion spliced by a user's fusion splicer; and a data management unit. The data management unit, in accordance with the command received from the user-side communication unit via a network, transmits the requested fusion condition among the plurality of fusion conditions inside the storage device to the user-side communication unit via the network so that the requested fusion condition is available for use in the fusion splicer. If the requested fusion condition was not in the database, the data management unit updates the database by causing the requested fusion condition to be newly created and storing the newly created fusion condition in the database.
