Low penalty, dual stage, broadband discrete Raman amplifier for high capacity WDM metro networks

Not Accessible

Your library or personal account may give you access


We present a broadband (>70nm), dual stage, discrete Raman amplifier built with small and standard core fibre with ~19.5dB net gain. We transmit 120Gb/s DP-QPSK signals over 3040km with 38 amplifications for a preFEC BER<3.8×10-3.
