Optical coupler assembly and method making the same

摘要

A coupler (30) includes an enclosure (32) sealing therein a fiber assembly (34) consisting essentially of a pair of fibers (36). The fiber assembly (34) includes a hourglass-like configuration (38) on the middle portion wherein a reinforcement structure (40) is applied to the neck portion (42) of said fiber assembly so as to enhance the strength thereof, so that the whole coupler (30) can own a better mechanical character for convenient and reliable usage.
