STRUCTURE FOR MOUNTING CONNECTOR ON END OF OPTICAL FIBER

摘要

Provided is a structure for mounting a connector on an end of an optical fiber, wherein heat generated at the end of the optical fiber when high NA light is propagated through the optical fiber can be effectively and rapidly radiated to thereby suppress the deterioration of the optical fiber. The optical fiber (10) on an end of which a connector is mounted by the connector mounting structure is comprised of a bare optical fiber (1) consisting of a core (1A) and a cladding (1B) and a resin layer (2) with which the bare optical fiber (1) is coated, and the resin layer (2) and the cladding (1B) are removed from the front end of the optical fiber to form an exposed core portion (11). The connector is provided with an optical fiber holding means (34) which has an optical fiber insertion hole (33) provided with an optical fiber holding structure (32) with a bellows-like inner surface (31). A terminal end (2A) of the resin layer (2) adjacent to the exposed core portion (11) at said end of the optical fiber is arranged in the optical fiber holding structure (32) and projections (31A) of the bellows-like inner surface (31) of the optical fiber holding structure (32) thrust into the resin layer (2) to hold the optical fiber.
