Abstract :
The transmission capacity of long-haul wavelength division-multiplexing (WDM) systems could be greatly increased by further increasing the available optical bandwidth. We experimentally demonstrate that the gain of broadband Raman amplification systems can be equalized by highly precise gain equalization technique. By establishing 48×10 Gbit/s WDM signal transmission over 6140 km, we confirm that the available optical bandwidth can be expanded to 33 nm
