3.08 Tbit/s (77 × 42.7 Gbit/s) WDM transmission over 1200 km fibre with 100 km repeater spacing using dual C- and L-band hybrid Raman/erbium-doped inline amplifiers

3.08 Tbit/s (77/spl times/42.7 Gbit/s) WDM transmission over 200 km fibre with 100 km amplifier spacing and 100 GHz channel spacing is demonstrated. Error-free transmission of all 77 channels is achieved by employing dual C- and L-band hybrid Raman erbium-doped inline amplifiers, experimental low dispersion slope TrueWave fiber, and forward error correction.
