Abstract: In this paper, we evaluate transmission in a 1 Tb/s (10 × 112 Gb/s) Nyquist-WDM PM-RZ-QPSK superchannel over a widely-deployed SMF-28 fiber with and without maximum a-posteriori (MAP) equalization. Over 1000 km can be reached with BER below the HD FEC limit and with a spectral efficiency of 4 b/s/Hz.

Key words: coherent detection, QPSK, maximum a-posteriori detection, Nyquist-WDM, superchannel
