Abstract

PURPOSE:To connect two fibers different in refractive index of the cores with a low loss by heating more strongly a fiber with higher refractive index of a core than a fiber with lower refractive index of a core. CONSTITUTION:A fiber 6 with higher refractive index of a core is allowed to contact with a fiber 7 with lower refractive index of a core and the connection. Central line 8 and an electrode central line 9 of discharging electrodes 1, 2 are shifted in their positions such that the fiber 6 having higher refractive index of a core is more strongly heated. When an optical fiber is heated, the refractive index becomes generally small, so by an execution of a discharge connection with such arrangement a refractive index change near a connection point becomes gentle, thus a connection with a low loss becomes possible. Further constitution in the invention can be also used for connecting optical fibers different in melting temperature.
