Abstract

Raman amplification technology has been widely proposed as a key enabler for the continued increase in channel count and per-channel data rate in dense WDM systems [1,2]. However, the optical pump power levels for Raman amplification are much higher than the power levels seen in traditional EDFA-based WDM systems. We demonstrate the feasibility of distributed Raman amplification in an 8×10Gb/s WDM experiment with five 120km spans incorporating 40km installed older-vintage fibers.
