Transoceanic twelve 10 Gbit/s WDM signal transmission experiment with individual channel dispersion-and-gain compensation and prechirped RZ pulse format

The authors demonstrate WDM signal transmission of a total capacity of 120 Gbit/s over 6240 km. Fibre dispersion and amplifier gain are optimised by using individual data channel compensators. It is also shown that applying prechirping to the return-to-zero pulses can improve the SNR by /spl sim/2 dB.
