DWDM 40 G transmission over trans-Pacific distance (10,000 km) casing CSRZ-DPSK, enhanced FEC and all-Raman amplified 100 km UltraWave/spl trade/ fiber spans

We demonstrate error-free DWDM transmission of forty 40 Gbit/s channels with 100 GHz spacing over 10,000 km dispersion-managed fiber using CSRZ-DPSK, enhanced FEC and all-Raman amplified spans with 100 km terrestrial length.
