3.2Tb/s (80 /spl times/ 42.7Gb/s) transmission over 20 /spl times/ 100km of non-zero dispersion fiber with simultaneous C + L-band dispersion compensation

Error-free transmission of eighty 40-Gb/s, 100-GHz spaced channels over 2000 km of TrueWave/spl reg/ REACH fiber is achieved. We employ 100-km all-Raman-amplified spans, dispersion-slope-matched dispersion compensating fiber modules covering a 75-nm band, carrier-suppressed return-to-zero modulation format, and forward error correction.
