Abstract
Methods for authenticating an optical transceiver module to a host are disclosed. The transceiver comprises a receive signal line for transferring data from the transceiver to the host and a transmit signal line for transferring data from the host to the transceiver in preparation for transmission to a communications network. The transceiver includes a controller having a processor in communication with the host, and a first memory register assignable by the processor. A consolidated laser driver/post amplifier is also included and features a pattern generator and a data switch. The pattern generator produces a string of bit values that serve as an authenticating data portion. The data switch selectively inputs the authenticating data portion to the receive signal line of the transceiver according to the state of the first memory register, enabling the authenticating data portion to be received by the host, thereby authenticating the transceiver.
