Quantization Noise Suppression With Noise-Shaping Technique in DMT-Modulated IM/DD Optical Interconnects Utilizing Low-Resolution DAC (W6A.19)

Presenter: ke bai, Sun Yat-Sen University

Beyond 100 Gb/s 16/32QAM DMT signal transmitting over 2-km SMF enabled by DAC with 4-bit quantization resolution in IM/DD system is experimentally demonstrated. With the noise-shaping technique, the system with 4-bit quantization presents the same performance as the conventional IM/DD system with quantization resolution of 8-bit at BER of 3.8×10-3.
