Claim:
1. A method comprising: receiving, at a first communication terminal, a first optical signal from a second communication terminal through a free space optical link; determining, by control hardware of the first communication terminal, a receiving power for the optical link at the first communication terminal based on the received first optical signal; adjusting, by the control hardware, an output amplification at the first communication terminal using the receiving power for the optical link at the first communication terminal, the output amplification adjusted to provide a second optical signal with a minimum transmission power for maintaining the optical link; and transmitting the second optical signal from the first communication terminal to the second communication terminal through the optical link, wherein when transmitting the second optical signal from the first communication terminal to the second communication terminal, transmitting a telemetry signal from the first communication terminal to the second communication terminal through the optical link, the telemetry signal providing the receiving power for the optical link at the first communication terminal based on at least one of: wherein the telemetry signal and the second optical signal are co-propagated through an optical amplifier at the first communication terminal prior to transmitting the second optical signal and the telemetry signal to the second communication terminal.
