Abstract
Enabled by adaptive notch filter for clock leakage suppression and noise shaping technique for redistribution of quantization noise in DAC, beyond 100Gb/s PAM-4 signal over 40-km SMF transmission in O-band with BER under 3.8×10-3 utilizing 4-bit resolution DAC is first experimentally demonstrated in this paper.
