Abstract

Spectral efficiency will be discussed as a key issue for long reach systems. Ready to deploy, 0.4 bit/s/Hz, N/spl times/10 Gbit/s experiments will be highlighted, as well as next generation 40 Gbit/s systems. Following already installed WDM systems at 2.5 Gbit/s, the deployment of the next generations at 10 Gbit/s and later at 40 Gbit/s will improve spectral efficiency over most of fibre types at the price of finding a compromise between reach, span loss and capacity. The key techniques to be controlled are the dispersion managed solitons, Raman amplification and foward error correction methods.
