Optical network laser auto-tuning methods and systems

A transceiver in accordance with claim 1, wherein the transceiver is a first transceiver, wherein the fourth optical channel is output from a second transceiver.

A transceiver in accordance with claim 1, wherein the fourth optical channel is passed through an optical filter.

A transceiver in accordance with claim 1, wherein the transmitter transmits the first, second, and third optical channels onto an optical fiber and the receiver receives the fourth optical channel from the optical fiber.

A transceiver in accordance with claim 1, wherein, the transmitter transmits the second optical channel a predetermined length of time after the transmission of the first optical channel, and the transmitter transmits the third optical channel the predetermined length of time after the transmission of the second optical channel.

A transceiver in accordance with claim 1, wherein, based at least in part on the information stored in the memory, the transmit transmits the third optical channel after a loss of signal condition associated with the fourth optical channel.
