ABSTRACT:
A pluggable optical transceiver with a function not affecting the command status of the host system appeared in the internal bus, which is coupled with the command line within the transceiver, even when the transceiver is plugged in the host system. The optical transceiver provides a power supply circuit and a control unit. The power supply circuit, by receiving an external electric power, generates an internal electric power with a substantial time lag from a moment when the optical transceiver is plugged in the host system. The control unit communicates with the host system through the command line pulled up to the external electric power within the optical transceiver.
