Power auto-tuning in optical transceivers based on out-of-band communication

A system for power auto-tuning, the system comprising:

• an optical transceiver comprising:
• one or more of optical receptacles, wherein each optical receptacle is configured to engage a corresponding one of one or more optical receptacle mates;
• and
• transceiver circuitry configured to enable communication of optical signals via the one or more of optical receptacles;
• wherein the optical transceiver is configured to:
• establish an optical connection with a peer optical transceiver;
• set a transmit (Tx) optical power, used during transmission of optical signals to the peer optical transceiver, to a pre-determined initial value;
• and
• perform power auto-tuning of the transmit (Tx) optical power during optical communication with the peer optical transceiver via the optical connection, wherein the optical transceiver is further configured to, when performing the power auto-tuning:
• obtain from the peer optical transceiver, peer-side power related data, wherein the peer-side power related data comprises receive (Rx) damage power of the peer optical transceiver;
• determine based on the peer-side power related data, a maximum value for a peer-side receive (Rx) optical power;
• and
• adjust the transmit (Tx) optical power to ensure that the peer-side receive (Rx) damage power is equal to or less than the maximum value.
