Transmission of 96×100G pre-filtered PDM-RZ-QPSK channels with 300% spectral efficiency over 10,608km and 400% spectral efficiency over 4,368km

We transmitted 96×100G pre-filtered PDM-RZ-QPSK channels with 300% spectral efficiency over 10,608km using 52km spans of 150μm 2 fiber and simple single-stage EDFAs. We also achieved 400% spectral efficiency over 4,368km using similar techniques.
