.Experimental study of interband and intraband crosstalk in WDM networks[J].Optoelectronics Letters,2008,4(1):42-44 Experimental study of interband and intraband crosstalk in WDM networks GUAN Ai-hong WANG Yu-hua College of lnformation Science and Technology, Henan University of Technology, Zhengzhou 450001, China Abstract:       The impacts of interband and intraband crosstalk are studied and compared experimentally. Results show that interband crosstalk can be removed with narrow-band filters and has no influence on signal. Intraband crosstalk will result in signal eye diagram close and BER increasing. When the polarization states of signal and crosstalk align, intraband crosstalk seriously decreases signal quality. But when they misalign, it has little influence. Coherent and incoherent crosstalk are studied experimentally. Results show that coherent crosstalk is less harmful to system performance than incoherent crosstalk.
