Abstract
A optical transmission system includes light sources generating light of at least two wavelengths, where any two adjacent wavelengths are separated by less than 10 nm. The wavelengths fall within the zero dispersion zone of an optical fiber, and may be shifted by 1 nm or less to reduce crosstalk effects.
