摘要： This invention provides an optical module that enables to reduce an optical coupling loss when an external force is applied to an optical connector mating with the optical module. The present optical module comprises an optical sub-assembly and an optical receptacle having a cavity for receiving the optical connector and a space for receiving the optical sub-assembly. The optical sub-assembly provides a flange in its outer surface and the head portion thereof passes through the partition wall between the cavity and the space. Between the flange of the optical sub-assembly and the partition wall of the optical receptacle provides an O-ring, whereby the head portion of the optical sub-assembly enables to displace in the cavity and automatically recovers its original position.

摘要： A heat dissipating mechanism from an optical assembly to housing without stressing the assembly against the housing is disclosed. The optical assembly has a box-shaped portion to install the optical device and the heat generating device. Among six walls of the box-shaped portion, rear and one side wall are provided for the signal transmission, and two side walls continuous to each other are provided for the heat conduction. The housing forms a hollow within which the optical assembly is set such that the two side walls of the optical assembly come in thermally contact with the bottom and one side wall of the hollow.

摘要： The present invention is to provide an intelligent pluggable transceiver improving an EMI tolerance with a simple mechanism. The optical transceiver of the invention comprises upper and lower housings (11, 12), a holder (81), optical assemblies (51, 61), a cover (14), a substrate (15) and a grip (13). The optical assemblies are fixed with the upper and lower housings together with the holder with interposing the conductive elastic member. Although the rear end of the substrate exposes outside the transceiver, the shield bracket and the ground pattern on the substrate shields the contact portion between the substrate and the upper housing and between the substrate and the cover. Moreover, the grip and the latch lever installed in the lower housing, and the elastic piece realize the latching/releasing mechanism of the transceiver with the host system.
