Impact of fiber nonlinearity on Tb/s PDM-OFDM transmission
19 July 2010
We discuss the impact of fiber nonlinearity on a recently-demonstrated 1.2-Tb/s polarization-division-multiplexed (PDM) coherent optical OFDM superchannel in long-haul transmission over 7200 km of ultra-large-area fiber. The improvement obtained by nonlinearity compensation is also discussed.
