摘要：
A method and system for reducing crosstalk among subcarriers of a super-channel may involve adjusting power levels of the subcarriers. In one example, power levels of edge and/or intermediate subcarriers may be reduced relative to center subcarriers in the super-channel band. The adjustment in power level may lead to overall reduction in optical signal-to-noise ratio degradation.
