Seamless 32/spl times/10 Gb/s transmission over 320 km of 1.55 /spl mu/m dispersion-shifted fiber using wavelengths ranging from 1546 nm to 1587 nm

This paper demonstrates 32/spl times/10 Gbit/s transmission over 1.55 /spl mu/m dispersion-shifted fiber. The channels are seamlessly allocated from 1546 nm to 1587 nm. Wideband optical amplifiers employing distributed Raman amplification are used as in-line amplifiers.
