Net 1.15-Tb/s/λ Transmission of PS-256 QAM Signal Using a 7.6-MHz Linewidth DFB Laser and Linear Equalization (Th2A.12)

Presenter: Xueyang Li, Peng Cheng Laboratory

We propose a carrier-leakage coherent transmitter that effectively enhances laser phase noise tolerance and demonstrate the transmission of single-wavelength net 1.15 Tb/s PS-256QAM signals over 80 km using a DFB laser with 7.6 MHz linewidth.
