Abstract	A single DCF module capable of compensating the dispersion in the full C+L-band of a prototype Raman optimized NZDF has been demonstrated. The residual dispersion from 1530 to 1610 nm was controlled within /spl plusmn/0.07 ps/(nm/spl middot/km). The dispersion margin for 40 Gbit/s transmission is around /spl plusmn/60 ps/nm/sup 3/. Therefore, It will be possible to transmit DWDM 40 Gbit channels in the full C+L-band for around 850 km without any per channel dispersion trimming. The module is also an ideal lumped Raman amplifier. Using a total pump power of 1042 mW an average net gain of 10.1 dB was demonstrated from 1530 to 1607 nm. Noise figure was less than 6 dB in whole wavelength range, and OSNR from double Rayleigh scattering was better than 40 dB. The module will be ideal for use together with the Raman optimized transmission fiber in all Raman systems. Such a system will compared to a conventional system with EDFA's not require any band splitting and therefore support more channel with less loss and lower cost.
