PURPOSE:To attain fusion splicing of both multicore and single core optical fibers by setting up a fusion discharge current value and an optical fiber inserting length at the time of fusion discharge electrically to a condition for single core optical fiber fusion splicing by the operation of a change-over switch. CONSTITUTION:Variable resistors 14a, 14b are arranged in parallel and connected to a change-over switch 15. The variable resistor 14a is set up so that the discharge current is 19mA, the variable resistor 14b is set up so that the discharge current is 15mA and both the discharge current values can be selected for multicore and single core optical fibers by the operation of the change-over switch 15. An improved inserting movement length setting mechanism can be obtained by adding a pair of an inserting movement length detecting plate 29 and a sensor 30 to an ordinary device and the pair of units are connected to a change-over switch 31, so that the inserting movement length can be set up to single core positions 27, 28 and multicore positions 29, 30 by switching the change-over switch 31. Consequently, the discharge current value and the optical fiber inserting movement length at the time of discharge can be set up by the operation of the change-over switch, so that fusion splicing of both the multicore and single core optical fibers can be attained. |
