420 Gbit/s (42 x 10 Gbit/s) WDM transmission over 4000 km of UltraWave fiber with100 km dispersion-managed spans and distributed Raman amplification
19 July 2001
42 x 10 Gbit/s wavelength division multiplexed transmission over 4000 km of UltraWave fiber with 100 km dispersion-managed spans and 50 GHz channel spacing is demonstrated. A new dispersion map and all-Raman distributed amplification are employed to obtain error-free transmission of all 42 channels without the use of forward error correction.
