OPTICAL CONNECTOR

摘要

An optical connector, which is capable of enhancing fittability into a cabinet, or the like on account of compactification and also avoiding problems of an increase of bend loss, a breakage, etc. of an optical fiber, can be provided, In an optical connector 1 that houses a fusion-spliced portion 13, in which a short optical fiber 5 that is fitted previously to an optical connector ferrule 85 and a coated optical fiber 3 are fusion spliced together and holds the fusion-spliced portion 13 therein, one end of a protection sleeve 87 made of the thermal shrinkage material that externally fixes the fusion-spliced portion 13 is coupled to the optical connector ferrule 85. An air escape hole 7f for escaping an air, which is confined in the protection sleeve 87 when the protection sleeve 87 is thermally shrunk and adhered closely to the optical connector ferrule 85, to the outside is formed in the optical connector ferrule 85.
