Advanced 400G-SerDes Modulations and Equalizers for GPU Cluster in AI Era
Sheng Chen, Zhengxiang Cheng, Ji Zhou +5
High-speed GPU cluster interconnects are evolving from 200 to 400 Gbps to meet the growing computing demands of artificial intelligence. We investigate high-order modulation and ad…
Timing Recovery for Non-Orthogonal Multiple Access with Asynchronous Clocks
Qingxin Lu, Haide Wang, Wenxuan Mo +3
A passive optical network (PON) based on non-orthogonal multiple access (NOMA) meets low latency and high capacity. In the NOMA-PON, the asynchronous clocks between the strong and…
Timing Recovery for Point-to-Multi-Point Coherent Passive Optical Networks
Ji Zhou, Jinyang Yang, Haide Wang +2
We propose a timing recovery for point-to-multi-point coherent passive optical networks. The results show that the proposed algorithm has low complexity and better robustness again…
Record Capacity-Reach of C band IM/DD Optical Systems over Dispersion-Uncompensated Links
Haide Wang, Ji Zhou, Jinlong Wei +5
We experimentally demonstrate a C band 100Gbit/s intensity modulation and direct detection entropy-loaded multi-rate Nyquist-subcarrier modulation signal over 100km dispersion-unco…
Fixed-State Log-MAP Detection for Intensity-Modulation and Direct-Detection Optical Systems over Dispersion-Uncompensated Links
Shuangyue Liu, Ji Zhou, Haide Wang +3
In this paper, an optimized detection based on log-maximum a posteriori estimation with the fixed number of surviving states (fixed-state Log-MAP) is proposed to cooperate with equ…
Adaptive Channel-Matched Detection for C-Band 64-Gbit/s Optical OOK System over 100-km Dispersion-Uncompensated Link
Haide Wang, Ji Zhou, Dong Guo +4
In this paper, we propose adaptive channel-matched detection (ACMD) for C-band 64-Gbit/s intensity-modulation and direct-detection (IM/DD) optical on-off keying (OOK) system over a…
