Selectable host-transceiver interface protocol

摘要

An optical transceiver, including a memory and a processor, which is capable of supporting different host interface protocols for communication between the optical transceiver and a host computing system. Each of the host interface protocols may be implemented by selecting microcode that corresponds to a particular host interface protocol and loading the microcode into the memory. The processor may later execute the microcode and cause the transceiver and the host to communicate using the specified interface protocol. The host interface protocols may also be implemented by hardware contained in the optical transceiver.
