Abstract :
We demonstrate a 40 Gb/s RZ DQPSK single channel transmission over 2900 km of SMF, using a 40 GHz bandwidth optical receiver filter to suppress ASE and improve OSNR. The interaction of SPM and accumulated dispersion is evaluated by minutely system dispersion management. Additionally, we successfully employ a 10 channel DWDM ranging from 1560.20 nm to 1563.86 nm at 40 Gb/s RZ DQPSK and 50 GHz of channel spacing over 1000 km, without raman amplification or special polarization multiplex.
