ABSTRACT:
The present invention provides an optical transceiver that reduces the EMI noise leaked from a portion between the receptacle body and the optical subassembly. The transceiver of the invention comprises the optical subassembly, the substrate, and the upper and lower housings. The subassembly built with the receptacle body is assembled with the housing as movable in vertical position. The assembly between the subassembly and the receptacle body is carried out by inserting the sleeve of the subassembly into the opening of the receptacle body. The cross section of the opening has an extended circular shape combined with a pair of flat portion in both sides thereof and a pair of arched portion connecting the flat portions. The interval between the flat portions is smaller than the diameter of the sleeve, while the diameter of the arched portion is greater than that of the sleeve. Since the sleeve is inserted into the opening as expanding the flat portions, not only no gap may be formed therebetween to prevent the EMI noise from leaking out but also the receptacle body may securely hold the subassembly.
