Nonlinear Limitations in a Joint Transmission of 100Gb/s O-OFDM and 40Gb/s DPSK over a 50 GHz Channel Grid
21 March 2010
: We evaluate the nonlinearity impact of neighbouring DPSK DWDM channels on one 100 Gb/s PDM-OFDM channel. A new DSP-based SPM correction scheme enables complete compensation of the degradation of the nonlinear threshold of 1.8 dB. 2010 Optical Society of America OCIS codes: (060.1660) Coherent communications, (060.4510) Optical communication
