ABSTRACT:
Unwanted, monotonic growth of sideband energy is avoided in wavelength-division-multiplexed and frequency-division-multiplexed lightwave communication systems by transmitting adjacent channels approximately 2 nm to 3 nm apart in the normal dispersion regime of the optical fiber for the system and by transmitting each channel more than 0.4 nm below a mean zero dispersion wavelength, .lambda..sub.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.
