240-km CWDM transmission using cascaded SOA Raman hybrid amplifiers with 70-nm bandwidth

We demonstrate the cascading of broad-band semiconductor optical amplifier-Raman hybrid amplifiers which provide nearly flat gain over 70 nm. A coarse-wavelength-division-multiplexing transmission system consisting of three spans of 80 km shows uniform performance and
