One aspect of the disclosure relates to an out-of-band communication system and associated process. The out-of-band communication system includes an encrypted data path that is configured to convey encrypted data. The out-of-band communication system includes an optical out-of-band channel that is physically distinct from the encrypted data path. The encrypted data path extends between an optical transmitter and an optical receiver. The optical out-of-band channel is configured to transmit key information from the optical transmitter to the optical receiver.
