摘要：
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. By utilizing 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 x10(-)(3).
