Title: Optical connection sleeve, optical module and optical communication module

Abstract: An optical connection sleeve 1 for optically connecting an optical fiber 41 and an optical device 51 is constituted by a resin sleeve 15 including an end portion 10 in which a ferrule 40 is inserted and a metal sleeve 16 including an end portion 12 on which the optical device 51 is disposed, the metal sleeve 16 being insert-molded in the resin sleeve 15 to be fixed thereto. With such a constitution, occurrence of positional deviation between the sleeve 1 and an optical device unit 50 is prevented, and the optical fiber 41 and the optical device 51 can be optically connected surely. Furthermore, it is prevented that the sleeve portion extending cylindrically functions as an antenna for electromagnetic noises. Accordingly, the optical connection sleeve in which the optical fiber and an optical component as the optical device are optically connected with high accuracy, and influences of the electromagnetic noises are fully reduced, an optical module and an optical communication module using the optical connection sleeve are realized.
