Abstract :
Unrepeatered transmission of 8 × 120 Gb/s PM-NRZ-QPSK signal over standard effective-area pure silica core fiber of 444.2 km (76.6 dB) is achieved using only forward and backward distributed Raman amplification and remotely-pumped erbium fiber. Multi-rate transmission of 8 × 120 Gb/s and 9 × 10.7 Gb/s over 75.4 dB span is also demonstrated.
