We achieve 1 Tb/s (100 × 10 Gb/s) super-dense WDM (super DWDM) transmission with 25-GHz channel spacing (0.4 bit/s/Hz spectral efficiency) in the zero-dispersion region over a 4 × 80 km dispersion-shifted fiber by employing backward pumped distributed Raman amplification and forward error correction. By adopting bi-directional pumping, we present experimental results showing that the transmission distance is extended approximately threefold to 1040 km.
