1. An optical communications system, comprising:

  • a modulator/demodulator (modem) to transmit outgoing communications data and to receive incoming communications data in a transceiver;

    a main detector coupled to the modem to convert an optical signal representing the incoming communications data to an electrical signal for the modem; and

    an adaptive data rate processor to monitor the electrical signal from the main detector to determine a current power level of the optical signal, wherein the adaptive data rate processor dynamically adjusts a data rate of the modem based on the determined current power level of the optical signal and commands the modem to a new data rate based upon detecting a power level change from the current power level, wherein the new data rate is based upon a predetermined power threshold.
