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…
Concatenated Forward Error Correction with KP4 and Single Parity Check Codes
Diego Lentner, Emna Ben Yacoub, Stefano Calabrò +3
Concatenated forward error correction is studied using an outer KP4 Reed-Solomon code with hard-decision decoding and inner single parity check (SPC) codes with Chase/Wagner soft-d…
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…
