We report the transmission of 40Gb/s channels over DWDM optically amplified communications systems employing RZ, NRZ, CS-RZ amplitude and differential phase shift keying modulation over 320 km standard SMF and 328 km dispersion compensating modules. Impacts of optical filtering of 10 Gb/s DWDM transmission system on these 40G modulation formats are reported. The mutual impacts of 10 Gb/s and 40 Gb/s co-transmission are proven to be minimum.
