Abstract
A method of connecting multicore fibersincludes a shaping step Sand a fusing step S. The multicore fiberssatisfy Y≧20, where a distance from a center of a corelocated on the outer periphery side of a cladto a side surface of the cladis defined as Y μm. The shaping step Sincludes heating a end surfacesto satisfy 0<X/Y≦0.0054Y+0.268, where a distance in a longitudinal direction from a portion of each multicore fiberlocated at an end in the longitudinal direction on each shaped end surfaceto a position at which the end surfaceand the side surface of the cladmeet each other is defined as X μm.
