Abstract :
We have demonstrated that the use of distributed Raman amplification offers significant benefits in terms of low noise accumulation and wide bandwidth for future long haul broadband WDM systems. In a system experiment, we successfully transmitted 10 channels at 10 Gbit/s over 7200 km. To demonstrate the potential bandwidth, we designed a 92 mm bandwidth distributed Raman amplifier with a 5 dB equivalent noise figure
