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…
Comparison of PAM-6 Modulations for Short-Reach Fiber-Optic Links with Intensity Modulation and Direct Detection
Tobias Prinz, Thomas Wiegart, Daniel Plabst +6
PAM-6 transmission is considered for short-reach fiber-optic links with intensity modulation and direct detection. Experiments show that probabilistically-shaped PAM-6 and a framed…
Experiments on Bipolar Transmission with Direct Detection
Thomas Wiegart, Daniel Plabst, Tobias Prinz +6
Achievable information rates of bipolar 4- and 8-ary constellations are experimentally compared to those of intensity modulation (IM) when using an oversampled direct detection rec…
Achievable Rates for Short-Reach Fiber-Optic Channels with Direct Detection
Daniel Plabst, Tobias Prinz, Thomas Wiegart +5
Spectrally efficient communication is studied for short-reach fiber-optic links with chromatic dispersion (CD) and receivers that employ direction-detection and oversampling. Achie…
PAM-6 Coded Modulation for IM/DD Channels with a Peak-Power Constraint
Tobias Prinz, Thomas Wiegart, Daniel Plabst +4
Coded modulation with probabilistic amplitude shaping (PAS) is considered for intensity modulation/direct detection channels with a transmitter peak-power constraint. PAS is used t…
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…
