Reduced dispersion fiber extends reach for dispersion tolerant systems

Dispersion-tolerant technologies like duobinary modulation and Rx-based EDC have gained significant media attention recently. These technologies have important implications for the future development of uncompensated short reach networks and are now maturing with duobinary products available from multiple companies. With Corning LEAF fiber, the integrated application of duobinary modulation with Rx-based EDC can deliver 1500 km of transmission reach without any in-line dispersion compensation and with attractive cost savings. So finally the goal of cost-effective extended reach transmission without any in-line dispersion compensation can be achieved, and this itself translates into a significant advantage for transparent and reconfigurable networks.
