Carrier Leakage Suppression and Power Difference Equalization for TFDMA Coherent PON
Ji Zhou, Haide Wang, Liangchuan Li +2
In this invited talk, we demonstrate the carrier leakage suppression and power difference equalization based on semiconductor optical amplifier (SOA) for TFDMA-based coherent PON,…
Low-Latency and Low-Complexity MLSE for Short-Reach Optical Interconnects
Mengqi Guo, Ji Zhou, Haide Wang +3
To meet the high-speed, low-latency, and low-complexity demand for optical interconnects, simplified maximum likelihood sequence estimation (MLSE) is proposed in this paper. Simpli…
Comparison of FTN-NOFDM and PCS-OFDM for Long-Haul Coherent Optical Communications
Haide Wang, Ji Zhou, Yongcheng Li +4
Single-wavelength 400G coherent optical communications have become a critical solution to meet the explosive traffic demands. However, the single-carrier modulation using low-order…
Real-Time Burst-Mode Digital Signal Processing for Passive Optical Networks
Ji Zhou, Kainan Wu, Haide Wang +6
Driven by the ever-increasing capacity demands, the 50G passive optical network (PON) is maturing gradually. One of the main challenges for the 50G PON is implementing burst-mode d…
