Abstract
An optical transmission system and method uses large-bandwidth optical signals that rapidly disperse in a transmission medium, such as an optical fiber, to reduce the effects of non-linearities in the transmission medium on the optical signal. The frequency bandwidth of the optical signals can be widened by chirping the optical signals, although other methods are possible. Optical signals in adjacent channels, such as in wavelength division multiplexing, can overlap to some extent without significant effect on the transmitted signal quality. Optical filtering at the receiver can extract partially overlapping signals as well as compensate for residual dispersion and/or dispersion slope in the transmission system.
