Analysis of non-linear impairments in 40 Gbaud PM DQPSK and D8PSK transmission
Paper in proceedings, 2010
In this paper, 40 Gbaud transmission of single polarization (SP) and Polarization-Multiplexed (PM), RZ-DQPSK and RZ-D8PSK signals is analyzed numerically. The impact of nonlinear crosstalk arising from the presence of neighbouring intensity-modulated channels is analyzed in terms of required OSNR for the BER of 10 -3 versus launch power. © 2010 IEEE.
