Impact of signal rise time on transient power amplitude in forward pumped Raman amplifiers

A numerical model describing transients in forward pumped Raman amplifiers has been experimentally validated. Use of realistic rise time (80 ns) for channel addition reduces signal overshoot to 0.2 dB in a 200 km span with 14.5 dB co-gain. (2 pages)
