SYSTEM AND METHOD FOR OPERATING A WIDEBAND RETURN CHANNEL IN A BI-DIRECTIONAL OPTICAL COMMUNICATION SYSTEM

摘要

An inventive system capable of being utilized in environments where laser transceiver nodes may be subject to extreme temperatures. Temperature changes in the laser transceiver nodes may be compensated for by utilizing a wide wavelength channel allocation for data sent upstream from the laser transceiver nodes (320A-E) to the data service hub (310). The wavelength channel allocations for upstream data may be wider than the wavelength channel allocations for downstream data. An exemplary embodiment of the inventive system may comprise a data service hub connected to one or more laser transceiver nodes by one or more optical waveguides (370, 380). Some embodiments with multiple optical waveguides are capable of practicing route redundancy. According to an exemplary embodiment of the inventive system, the optical waveguides are capable of carrying multiple optical signals at different wavelengths in order to serve a plurality of laser transceiver nodes.
