An optical transceiver is disclosed, in which an optical subassembly may be assembled within a housing without degrading an optical coupling efficiency between a semiconductor optical device in the subassembly and an optical fiber in an external optical connected that is mated with the housing of the transceiver. The subassembly comprises a sleeve portion and a body portion that installs the optical device therein. The subassembly is assembled in the housing such that the sleeve portion thereof is put between the holder and the cover. The holder and the cover each provides a concave surface that comes in contact with the sleeve portion only by two lines in parallel to the optical axis of the subassembly when the sleeve portion is set within the concave surface.

The present is closely related to a prior application, Ser. No. 12/076,099, filed on Mar. 13, 2008, entitled “Optical transceiver with mechanism to dissipate heat efficiently without affecting optical coupling condition,” which is incorporated herein by reference in its entirety.
1. Field of the Invention
The present invention relates to a pluggable optical transceiver.
FIG. 1A is a perspective view of the optical transceiver following the X2 specification according to the present invention, FIG. 1B is a plan view and FIG. 1C is a side views of the optical transceiver;
FIG. 2A is an exploded view of the optical transceiver, and FIG. 2B shows an inside of the optical transceiver which is an appearance after the assembly of the subassemblies and the circuit board are completed;
FIGS. 3A and 3B are the plan and the side views of the optical sub-assembly, and FIG. 3C is a perspective view of the optical transceiver;
FIG. 1A is a perspective drawing of one example of an optical transceiver according to the present invention, FIG. 1B is a top view, while, FIG. 1C is a side view of the transceiver. FIG. 2A is an exploded view and FIG. 2B removes an upper frame 11 to expose the inside of the transceiver.
The transceiver 1 provides upper and lower frames, 11 and 12, and a cover 13. These frames constitute a housing whose specifications follow the XENPAK and X2 standard specified in IEEE 802.3a. The upper and lower frames, 11 and 12, form an optical receptacle 21 into which an external optical connector that secures an optical fiber is to be inserted. In the explanation below, the front of the transceiver 1 corresponds to a side where the optical receptacle 21 is provided, while, the rear is an opposite side.
The side of the housing each exposes a latch tab 20a. When the transceiver 1 is set on a pair of rails provided in the circuit board of the host system, the latch tab 20a mates with the opening formed in the side of the rail, which the transceiver 1 is to be engaged with the host system such that a portion in front of the flange 12 exposes from the host system.
