Three-carrier 1 Tbit/s Dual Polarization 16-QAM Superchannel Using Look-Up Table Correction and Optical Pulse Shaping

By using look-up table correction for pattern-dependent distortion and optical pulse shaping for enhancing the spectral efficiency, a three-carrier 1.206 Tbit/s dual-polarization 16-QAM superchannel exhibits a back-to-back OSNR sensitivity of 25.9 dB (BER = 10-3), a net spectral efficiency of 4.47 b/s/Hz, and transmission over 1500 km of SMF.
