Abstract
The present disclosure provides systems and methods for channel power offsets for multi-rate dense wave division multiplexed (DWDM) transmission over optical add-drop multiplexers (OADMs). The present invention includes algorithms to set power levels of each type of channel in different sections of a fiber system to optimize the performance of that type of channel at the receiver. For example, the present invention can optimize power levels based on different channel modulation formats, bit rates, channel spacings, and the like. Advantageously, the present invention improves the total capacity (bit rate) and reach that channels of a given bit rate can achieve, and maximizes the reach of channels without sacrificing capacity.
