OPTIMIZED WAVELENGTH-DIVISION-MULTIPLEXED LIGHTWAVE COMMUNICATION SYSTEM Unwanted, monotonic growth of sideband energy is avoided in wavelength-division-multiplexed and frequency-division-multiplexed lightwave communication systems by transmitting adjacent channels approximately 2nm to 3nm apart in the normal dispersion regime of the optical fiber for the system and by transmitting each channel more than 0.4nm below a mean zero dispersion wavelength, .lambda.0, of the optical fiber. Interchannel spacing and individual channel separation from the zero dispersion wavelength are measured with respect to a nominal carrier wavelength for each channel.
