Experimental demonstration of 20-Gb/s dual-band Nyquist PAM-4 transmission over a short-reach IMDD system using super-Nyquist sampling technique

In this Letter, we experimentally demonstrate a 1550-nm direct modulation laser (DML)-based dual-band Nyquist PAM-4 intensity modulation direct detection (IMDD) system using a real-time field programmable gate array (FPGA)-based receiver. Although the sampling rate of the analog-to-digital ...
