Dependence of non-linear impairments on polarization state and baud rate in WDM systems with mixed DQPSK and OOK channels
2011 (English)Conference paper (Refereed)
In this paper, transmission of Polarization-Multiplexed (PM), RZ-DQPSK is analyzed numerically with copropagation of intensity modulated non return to zero on off keying (NRZ OOK) channels. The dependence of nonlinear crosstalk on baud rate (10 Gbaud, 28 Gbaud and 56 Gbaud) and relative state of polarization (SOPs) of PM RZ DQPSK and neighbouring NRZ OOK channels is analyzed in terms of required OSNR for the BER of 10 -3 versus launch power. From the results we observe that non-linear impairments are highly dependent on relative SOPs and less dependent on baud rates of the PM RZ DQPSK test channel.
