The feasibility of NRZ- and RZ-DQPSK for 112 Gb/s DWDM transmission is analyzed. RZ-DQPSK is more tolerant to cascaded filtering, chromatic dispersion and non-linearities. Cascaded filtering is the most critical issue for 100 GHz channel spacing.
We demonstrate the use of spectrograms for pulse monitoring. The technique can characterize the phase and intensity of data modulated pulses after transmission over a fiber span including a tunable dispersion compensating grating
We propose to suppress intra-channel four-wave-mixing (IFWM) in 40 Gbit/s optical transmission by applying a phase modulation at 10 GHz. Both numerical simulations and experiments show that the penalty induced by IFWM is significantly reduced
