The transmission of many Wavelength Division Multiplexed (WDM) channels over transoceanic distances can be limited by the nonlinear interactions between channels. In this work the nonlinear interactions were suppressed by tailoring the chromatic dispersion of the transmission fiber1 and operating the system at low channel power. These techniques made possible the transmission of eight 5 Gb/s Non-Return-to-Zero (NRZ) channels over 8000 km for a total transmission capacity of 40 Gb/s.
