ABSTRACT:
An optical transceiver (or optical transmitter or optical receiver) that has at least one processor and a memory. The optical transceiver receives encrypted microcode from a source. The optical transceiver may then decrypt the received microcode to create decrypted microcode. The decrypted microcode is then written to the memory, where it may be executed by the at least one processor. The microcode, when executed by the at least one processor, controls one or more functions of the optical transceiver.
