  • Publication number: 20130315582
    Abstract: An optical communication module includes a control unit and a nonvolatile memory. The control unit detects an abnormality of the optical communication module, generates log information regarding the detected abnormality, and writes the log information in the nonvolatile memory. After the number of times the log information has been written in the nonvolatile memory has reached a predetermined number of times, the control unit does not write log information in the nonvolatile memory. Accordingly, the number of times the nonvolatile memory is permitted to be written can be prevented from considerably decreasing.

  • Publication number: 20090067849
    Abstract: 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 gasket 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.

  • Patent number: 7195403
    Abstract: The present invention is to provide an intelligent pluggable transceiver improving EMI tolerance with a simple mechanism. The optical transceiver of the invention includes upper and lower housings, a holder, optical assemblies, a cover, a substrate and a grip. The optical assemblies are fixed with the upper and lower housings together with the holder by interposing a conductive elastic member. Although the rear end of the substrate is exposed outside of the transceiver, the shield gasket and the ground pattern on the substrate shield 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.
