200Gb/s VCSEL transmission using 60m OM4 MMF and KP4 FEC for AI computing clusters
Tom Wettlin, Youxi Lin, Nebojsa Stojanovic +4
We show a beyond 200Gb/s VCSEL transmission experiment. Results are based on 35GHz VCSEL and advanced DSP. We show an AIR of 245Gb/s PAM-6 back-to-back, and 200Gb/s PAM-4 over 60m…
Probabilistic Shaping for High-Speed Unamplified IM/DD Systems with an O-Band EML
Md Sabbir-Bin Hossain, Georg Bocherer, Talha Rahman +4
Probabilistic constellation shaping has been used in long-haul optically amplified coherent systems for its capability to approach the Shannon limit and realize fine rate granulari…
Experimental Comparison of PAM-8 Probabilistic Shaping with Different Gaussian Orders at 200 Gb/s Net Rate in IM/DD System with O-Band TOSA
Md Sabbir-Bin Hossain, Georg Böcherer, Youxi Lin +10
For 200Gb/s net rates, cap probabilistic shaped PAM-8 with different Gaussian orders are experimentally compared against uniform PAM-8. In back-to-back and 5km measurements, cap-sh…
Experimental Comparison of Cap and Cup Probabilistically Shaped PAM for O-Band IM/DD Transmission System
Md Sabbir-Bin Hossain, Georg Boecherer, Talha Rahman +9
For 200Gbit/s net rates, uniform PAM-4, 6 and 8 are experimentally compared against probabilistic shaped PAM-8 cap and cup variants. In back-to-back and 20km measurements, cap shap…
Complexity Reduction of Volterra Nonlinear Equalization for Optical Short-Reach IM/DD Systems
Tom Wettlin, Talha Rahman, Jinlong Wei +3
We investigate approaches to reduce the computational complexity of Volterra nonlinear equalizers (VNLEs) for short-reach optical transmission systems using intensity modulation an…
