Abstract :
Unrepeatered transmission of 34 × 120 Gb/s PM-NRZ-QPSK signal over 432.8 km of standard effective-area pure-silica-core fiber (74.4 dB) is achieved using forward and backward distributed Raman amplification and remotely-pumped erbium fiber. Transmission has been demonstrated using a commercial 100G channel card with real-time ASIC processor.
