Optical transceiver
View Patent ↗An optical transceiver has: an optical subassembly (OSA) having a built-in optical element and a cylindrical receptacle to conduct an optical path from the optical element; a chassis having an entrance that allows insertion of an optical fiber to be connected to the optical path; an OSA holder engaged with the receptacle to hold the OSA and accommodated in contact with an inside portion of the chassis; and an OSA holder-regulating portion formed in the chassis to regulate the OSA holder, the OSA holder-regulating portion being positioned opposite the entrance relative to the OSA holder.
1. An optical transceiver, comprising:
an optical subassembly comprising a built-in optical element and a cylindrical receptacle to conduct an optical path from the optical element;
a chassis comprising an entrance that allows insertion of an optical fiber to be connected to the optical path;
an optical subassembly holder engaged with the receptacle to hold the optical subassembly and accommodated in contact with an inside portion of the chassis; and
an optical subassembly holder-regulating portion formed in the chassis to regulate the optical subassembly holder, the optical subassembly holder-regulating portion being positioned opposite the entrance relative to the optical subassembly holder;
wherein:
the receptacle comprises a positioning flange,
the optical subassembly holder comprises a mated flange to sandwich the positioning flange, and
the mated flange comprises an inclined end face.
2. An optical transceiver, comprising:

the positioning flange comprises an inclined end face.
3. An optical transceiver comprising:
an optical subassembly comprising a built-in optical element and a cylindrical receptacle to conduct an optical path from the optical element;
a chassis comprising an entrance that allows insertion of an optical fiber to be connected to the optical path;
an optical subassembly holder engaged with the receptacle to hold the optical subassembly and accommodated in contact with an inside portion of the chassis; and
an optical subassembly holder-regulating portion formed in the chassis to regulate the optical subassembly holder, the optical subassembly holder-regulating portion being positioned opposite the entrance relative to the optical subassembly holder; and
an elastic member interposed between the optical subassembly holder and the entrance,
wherein the elastic member allows the optical subassembly holder to be pressed against the optical subassembly holder-regulating portion.
4. The optical transceiver according to claim 3 , wherein: the elastic member comprises a metallic leaf spring.
