ABSTRACT:
An optical module that includes a plastic package main body and at least one sleeve formed integrally with the package main body is disclosed. The sleeve receives and holds a ferrule provided on an end portion of an optical fiber. The sleeve has a substantially cylindrical shape, and is defined by at least first and second portions. At least the second portion has an inner surface with a plurality of grooves formed therein. The grooves extend in a longitudinal direction of the sleeve and are circumferentially spaced to each other to define protuberant regions therebetween. The inner surface of the second portion and the ferrule have substantially the same diameters, such that the protuberant regions make contact with and support the ferrule.
