Optimal single-channel transmission can be obtained by simultaneously minimizing the nonlinear distortion of a single pulse and the nonlinear interaction among several pulses. This is demonstrated by numerical simulations based on a simple analytical theory of the chirp induced by the nonlinearity. The resulting fiber nonlinearity can be properly used to manage the pulse bandwidth evolution, allowing periodic behavior. As such, a 40 Gbit/s soliton signal can be transmitted over a record distance of 1800 km in a link that encompasses step-index fibers, with 100-km amplifier spacing and group-velocity-dispersion compensation by gratings.

Abstract
Optimal single-channel transmission can be obtained by simultaneously minimizing the nonlinear distortion of a single pulse and the nonlinear interaction among several pulses. This is demonstrated by numerical simulations based on a simple analytical theory of the chirp induced by the nonlinearity. The resulting fiber nonlinearity can be properly used to manage the pulse bandwidth evolution, allowing periodic behavior. As such, a 40 Gbit/s soliton signal can be transmitted over a record distance of 1800 km in a link that encompasses step-index fibers, with 100-km amplifier spacing and group-velocity-dispersion compensation by gratings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
