Abstract :
Results are reported of 40 Gbit/s DWDM transmission over distances greater than 1000 km on several commercially available fibre types using a single 53 nm transmission band. The use of a wide singleband is made possible by forward and backward Raman amplification and makes for an easier system design and better footprint. Large Q-margins are demonstrated for all tested configurations.
