摘要： The present invention provides an optical module capable of being readily dismounted from a host board while solving the problem discussed in the specification. An optical module 10 according to the present invention is an optical module 10 to be inset into a host board 40, which comprises a projection 15 formed in a housing 14 and adapted to engage with a hook 41 provided in the host board 40, and a lever 20 pivotably mounted on the housing 14 in order to disengage the hook 41 engaging with the projection 15 to release the engagement, wherein the lever 20 has a first portion 21A adapted to move with exertion of a force in a direction toward the housing 14, and a second portion 21B being adjacent to the projection 15 and adapted to move according to the movement of the first portion 21A. In this arrangement, as the first portion 21A moves with exertion of the force on the first portion 21A, the second portion 21B moves in an upheaving direction of the projection 15 to release the engagement between the hook 41 and the projection 15.

摘要： The optical pluggable transceiver according to the present invention has features of a good heat dissipating function with a simplified configuration thereby reducing the cost of not only the component used but also the process itself. The transceiver of the present invention comprises a resin frame, an optical subassembly, a electronic substrate, both mounted on the frame, a heat dissipating member, made of metal, for conducting and radiating heat generated by the electronic circuit on the substrate, and a metal cover for putting these frame, subassembly, substrate, and heat dissipating member therein. A greater part of the surface of the heat dissipating member exposes from the cover, accordingly, the efficiency for radiating heat may be improved. Moreover, these members of the frame, the optical subassembly, the substrate, the heat dissipating member, and the cover are assembled only by fitting without screwing or gluing. Accordingly, the manufacturing process of the transceiver can be extremely simplified.

摘要： A light-emitting element is mounted on a first conversion element mounting portion prepared on a lead frame and resin-molded by using a mold. In this case, a focusing lens whose optical axis coincides with the major surface of the light-emitting element and a coupling portion in which a sleeve is fitted are integrally molded at once to mold a transmission section and an electronic circuit section. When these member are fixed in housings, and a ferrule holding an optical fiber is inserted in the sleeve fitted in a recess portion of the coupling portion, the optical fiber is optically coupled to the major surface of the light-emitting element. At this time, when the distal end portion of the sleeve is brought into contact with the abutment portion in the coupling portion, the end face of the optical fiber always coincides with the major surface of the light-emitting element, thereby realizing reliable optical axis alignment.
