Abstract
A method includes a first optical transmitter generating a first data signal at a first end of a fiber optic cable, wherein the first optical transmitter and a first photodetector are included in a first optical transceiver. The method further includes a second photodetector receiving a second data signal at a second end of the fiber optic cable. The second photodetector and the a second optical transmitter are included in a second optical transceiver, and the second data signal is the result of the first data signal passing from the first optical transmitter through the fiber optic cable to the second photodetector. A bit error rate in the second data signal is determined and, in response to the bit error rate exceeding a setpoint, the second optical transmitter sends a message to the first photodetector. The power output of the first optical transmitter is increased responsive to the message.
