1. A multi-wavelength cable television (CATV) transmission system comprising transmitters adapted to emit optical carrier wavelengths on a 12.5 GHz+/−20% ITU grid with a minimum spacing of 37.5 GHz+/−20% between optical carriers or with a minimum spacing of 37.5 GHz+/−20% between optical carriers and their optical beat product groups, wherein the minimum spacing precludes beat groups having a mitigated power level higher than a predetermined threshold level from overlapping with an optical carrier. |
