Burst-mode timing recovery based on fourth-power phase detector for passive optical networks
Ji Zhou, Haide Wang, Xiaofeng Zhang +5
Driven by the ever-increasing capacity demands, 50G passive optical network (50G-PON) is ready for practical application. It is highly challenging to realize 50GHz burst-mode analo…
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,…
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…
Burst-Mode Digital Signal Processing for Coherent Optical Time-Division Multiple Access
Ji Zhou, Cheng Li, Haide Wang +3
As the 50G optical access gradually matures, it is time to discuss Beyond 50G optical access. According to the evolution rules of optical access standards, Beyond 50G optical acces…
Preamble Design and Burst-Mode DSP for Upstream Reception of 200G Coherent TDM-PON
Haide Wang, Ji Zhou, Jinyang Yang +4
Burst-mode DSP based on 10ns preamble is proposed for upstream reception of 200G coherent TDM-PON. The 128-symbol tone preamble is used for SOP, frequency offset, and sampling phas…
IQ Skew and Imbalance Estimation for Coherent Point-to-Multi-Point Optical Networks
