Abstract

We demonstrated that simple pre-filtering at the transmitter to constrain the channel bandwidth together with a maximum a posteriori probability (MAP) detection algorithm can significantly improve spectral efficiency (SE). 96$\,\times\,$100-Gb/s bandwidth-constrained polarization-division-multiplexing return- to-zero-QPSK channels were transmitted with 300% SE over 10 610 km using 52-km spans of 150-$\mu$m $^{2}$ fiber and simple single-stage erbium-doped fiber amplifiers without any Raman amplification. We also achieved 400% SE over 4370 km using similar techniques.
