Abstract
This paper investigates serial 100 Gbit/s PM-RZ-DQPSK transmission in the presence of perturbations from neighboring 10 Gbit/s NRZ, 40 Gbit/s RZ-DPSK, and 40 Gbit/s RZ-DQPSK DWDM channels. It addresses the need to outline upgrade paths of current hybrid DWDM systems equipped with 10 and 40 Gbit/s line cards towards 100 Gbit/s for remaining channels. A numerical simulation approach is used to evaluate the signal quality of the central probe for various DWDM channel constellations and power levels.
