Title :
Quantitative analysis of second order distributed Raman amplification
Abstract :
We have experimentally quantified the OSNR improvements achievable with second order distributed Raman pumping, and the associated tradeoffs in terms of pump power efficiency. The results are very accurately predicted by a model using measured fiber parameters and taking into account the pump-signal and pump-pump Raman interactions.
