摘要:
A small-sized optical transceiver module, wherein any stress attributable to the differences in coefficient of thermal expansion between a transmission section optical system, a receiving section optical system, and the components which integrate and fix them and the like is not applied therebetween, and which is not influenced by any stress at the time of attachment/detachment of the optical connector is disclosed. The optical transceiver module is one wherein the transmission section optical system 1 which comprises a laser diode and an optical fiber or an optical waveguide optically connected to the laser diode and of which the electric input terminal of the laser diode is a flexible cable, a receiving section optical system 2 which comprises a photo diode and an optical fiber or an optical waveguide optically connected to the photo diode and of which the electric output terminal of the photo diode is a flexible cable, and an optical I/O optical receptacle 3 are optically connected, mechanically integrated and fixed, and the two flexible cables are spatially spaced out and disposed.
摘要:
It is an object of the present invention to provide a light sending and receiving module by a ferrule, a connecting device of the light sending and receiving module and a method of manufacturing the light sending and receiving module characterized in that: the light sending and receiving module is interposed between the butting faces of the optical fibers without embedding an optical filter; deterioration of the optical characteristic can be prevented by eliminating a gap between the optical fiber and the optical filter; the number of ferrules is decreased so as to reduce the manufacturing cost; and further the size can be reduced by omitting an adapter. According to the present invention, there are provided a ferrule joining member (1A), in which a portion or all of the circumferential face of an optical fiber (4) is exposed from an end portion of the ferrule in which the optical fiber (4) is embedded, and a guide sleeve (2A) for positioning into which the ferrule joining member (1A) is inserted. When end faces of the optical fibers (4) are butted to each other via an optical filter (5) so as to conduct light branching, the optical fibers (4) are optically coupled to each other. Due to the above structure, no gaps are formed between the optical fiber (4) and the optical filter (5). Therefore, the occurrence of irregular reflection can be prevented.
