ABSTRACT:
In an optical fiber fusion reinforcing device, a distance from an end face723to a mid point C6of a reinforcing device7is set equal to a distance from a fusion splicing point M to an end face of a fusion splicing device6where optical fibers3, 3are inserted. The fusion splicing device7includes: positioning member72for aligning a mid point C7of a heat shrinkable reinforcing member13, which is slidably mounted on the fusion spliced optical fibers, and the fusion splicing point M of the optical fibers3, 3with each other; housing portion for housing the optical fibers3, 3and the heat shrinkable reinforcing member13so that the fusion splicing point M and the mid point of the heat shrinkable reinforcing member13are aligned, and heater for melting the heat shrinkable reinforcing member13in the housing portion.
