Abstract
A 56-Gb/s 16-QAM signal was generated using subcarrier modulation with a subcarrier frequency of half the symbol rate, Nyquist pulse shaping, and a directly modulated passive feedback laser. Using a pre-amplified direct detection receiver and digital signal processing, a loss margin of 12.6 dB was achieved for a 112-Gb/s dual polarization signal.
