Sn. Knudsen et al., 420 Gbit/s (42 x 10 Gbit/s) WDM transmission over 4000 km of UltraWave fibre with 100 km dispersion-managed spans and distributed Raman amplification, ELECTR LETT, 37(15), 2001, pp. 965-967
42 x 10Gbit/s Wavelength division multiplexed transmission over 4000km of U
ltraWave fibre With 100km dispersion-managed spans and 50GHz channel spacin
g is demonstrated, A new dispersion map and all-Raman distributed amplifica
tion are employed to obtain error-free transmission of all 42 channels with
out the use of forward error correction.
