Ultra-Long-Haul Transmission of 16×112 Gb/s Spectrally-Engineered DAC-Generated Nyquist-WDM PM-16QAM Channels with 1.05×(Symbol-Rate) Frequency Spacing

Abstract

Using serial-transmission 112Gb/s PM-16QAM we achieved net SE 7.12 and 6.32 b/s/Hz, and SE(x)distance 13,949 and 23,396 b/s/Hz·km, for 7% and 20.5% FEC overhead, respectively, by means of DAC-enabled spectral engineering, over high-performance PSCF.
