Comparative Study of Crosstalk Created in 50 GHz-Spaced Wavelength Selective Switch for Various Modulation Formats at 43 Gbit/s
24 September 2006
We investigate the tolerance of PSBT, DQPSK and RZ-DQPSK formats to in-band crosstalk at 43 Gbit/s when considering 50 GHz-spaced Wavelength Selective Switches. We show that PSBT and DQPSK exhibit the best margins versus crosstalk.
