20 Tbit/s capacity transmission over 6,860 km

We transmit 198x100G pre-filtered PDM-RZ-QPSK channels with 400% spectral efficiency over 6,860 km. We also show that 100G coherent nonlinear performance scales differently with distance on uncompensated dispersion maps than expected from direct-detection transmission.
