Influence of polarization scattering on polarization-assisted OSNR monitoring in dense WDM systems with NZ-DSF and Raman amplification
06 March 2005
We show experimentally that the inter-channel XPM induced polarization scattering can cause large errors for polarization-assisted OSNR monitoring techniques in a dense WDM system with NZ-DSF, Raman amplification and RZ modulation signals.
