optical fiber communication conference | 2000

Network application and system demonstration of WDM systems with very large spans (error-free 32/spl times/10 Gbit/s 750 km transmission over 3 amplified spans of 250 km)

Jean-Pierre Blondel; Francois Boubal; Eric Brandon; Laurence Buet; Laurent Labrunie; P. Le Roux; Denis Toullier

We present the network applications of WDM systems with very large spans. Enabling technologies are low loss fiber, large launch powers, Raman preamplification and forward error correction. An experiment using all these technologies is presented.
