摘要： A WDM fiber optic communication system is operative to transmit WDM signals between multiple nodes. Each node has a booster EDFA, and in-band and out-of-band supervisory channels monitoring the integrity of a link by generating and detecting respective in-band and out-of-band control signals. The booster EDFA receives the multiplexed WDM and IB signals and generates an output signal carried by fibers between the nodes. The booster EDFA switches from an automatic gain control regime upon detecting of at least one of the IB and OB control signals to an automatic power control regime upon loss of both IB and OB control signals. The output signal of the EDFA in the AGC regime has a high power sufficient for transmitting the WDM and IB signals, and has a low power in the APC regime sufficient for transmitting only the IB control signal.

摘要： A wavelength division multiplexing (WDM) fiber optic communication system is operative to transmit WDM signals between multiple nodes. Each of the nodes has a booster EDFA, and in-band (IB) and out-of-band (OB) supervisory channels operative to monitor the integrity of a transmission link by generating and detecting respective in-band and out-of-band control signals. The booster EDFA is operative to receive the multiplexed WDM and IB signals and generate an output signal carried by a plurality of fiber-optic cables between the nodes. The booster EDFA is operative to switch from an automatic gain control regime upon detecting of at least one of the IB and OB signals to an automatic power control regime upon loss of both IB and OB signals. The output signal of the EDFA in the AGC regime has a high power sufficient for being transmitted the WDM and IB signals, and has a low power in the APC regime sufficient for transmitting only the IB signal between the nodes.

摘要： A downstream baseline optical signal generated by a baseline optical link is combined with a second optical signal generated by an additional optical link to generate a broadband optical signal. A fiber optic network splits the broadband optical signal to a plurality of fiber drops. An optical network termination unit receives the broadband optical signal from the fiber drop and isolates the downstream baseline optical signal and the second downstream optical signal from the broadband optical signal. An upstream baseline optical signal may also be transmitted through the fiber drop by the optical termination unit. The optical termination unit does not effect baseline optical service to any other optical termination unit in the fiber optic network.
