16 Gbit/s, 70 km, Pulse Transmission by Simultaneous Dispersion and Loss Compensation with 1.5microns Optical Amlifiers.

A scheme for using semiconductor laser amplifiers for simultaneous compensation of both the fiber loss and the fiber dispersion in the 1.5microns region is proposed and demonstrated. Experimentally, we demonstrate propagation of 16 Gbit/s pulses over 70 km of non-dispersion shifted fiber at 1.53microns wavelength. This distance is four times longer than the fundamental dispersion limit for transform-limited pulses.
