800 Gbit/s (80 x 10.664 Gbit/s) WDM transmission over 5200 km of fibre employing 100km dispersion-managed spans
22 November 2001
80 x 10.664 Gbit/s wavelength division multiplexed transmission over 5200 km of fibre with 100 km amplified spans and 50 GHz channel spacing is demonstrated. Error-free operation of all 80 channels is achieved by using dispersion-managed fibre spans, distributed Raman amplification, and forward error correction.
