Unrepeatered transmission of 8 x 120 Gb/s over 444.2 km (76.6 dB) and multi-rate transmission of 8 x 120 Gb/s and 9 x 10.7 Gb/s over a 75.4 dB span have been demonstrated with off-line digital processing for the coherent 120 Gb/s channels. Transmission of 2 x 120 Gb/s with 7 x 12.5 Gb/s over 78 dB is also demonstrated with a real-time ASIC processor. All transmission results have been achieved using standard effective-area pure-silica-core fiber using forward and backward distributed Raman amplification and remotely-pumped erbium fiber. ASIC real-time processed results match well with off-line processing.
