Abstract
We achieve 1 Tb/s (100 x 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 x 80 km dispersion-shifted fiber by employing b ackward pumped distributed Raman amplification and forward error correction . By adopting bi-directional pumping, we present experimental results showi ng that the transmission distance is extended approximately threefold to 10 40 km.
