Probabilistic Shaping and Forward Error Correction for Fiber-Optic Communication Systems

Journal of Lightwave Technology, 2019
This tutorial paper provides a foundation for integrating probabilistic shaping (PS) and forward error correction (FEC). A layered PS-FEC architecture consisting of a PS encoder and an FEC encoder is introduced, of which probabilistic amplitude shaping ...

Real-Time FPGA Investigation of Potential FEC Schemes for 800G-ZR/ZR+ Forward Error Correction

Journal of Lightwave Technology, 2023
Forward error correction (FEC) performance down to 1e-15 bit error rate (BER) of a open FEC code (OFEC), which was recently proposed for the 800G inter-data center interconnect (DCI) standard, is verified with a 100-piece-FPGA implementation at a record ...

RL-AFEC: adaptive forward error correction for real-time video communication based on reinforcement learning

ACM SIGMM Conference on Multimedia Systems, 2022
Real-time video communication is profoundly changing people's lives, especially in today's pandemic situation. However, packet loss during video transmission degrades reconstructed video quality, thus impairing users' Quality of Experience (QoE). Forward

Real-Time FPGA Investigation of Interplay Between Probabilistic Shaping and Forward Error Correction

Journal of Lightwave Technology, 2022
In this work, we implement a complete probabilistic amplitude shaping (PAS) architecture on a field-programmable gate array (FPGA) platform to study the interplay between probabilistic shaping (PS) and forward error correction (FEC).

Low-complexity Forward Error Correction For 800G Unamplified Campus Link

International Conference on Optical Communications and Networks, 2022
The discussion about forward error correction (FEC) used for 800G unamplified link (800LR) is ongoing. Aiming at two potential options for FEC bit error ratio (BER) threshold, we propose two FEC schemes, respectively based on channel-polarized (CP ...

Error-free PAM-4 transmission by a high-speed plastic optical fiber without forward error correction.

Optics Letters, 2021
This Letter reports, to the best of our knowledge, the first study in which error-free four-level pulse-amplitude modulation (PAM-4) transmission has been achieved using a graded-index plastic optical fiber (GI POF) without the use of forward error ...

Investigation of Potential FEC Schemes for 800G-ZR Forward Error Correction

Optical Fiber Communications Conference and Exhibition, 2022
With a record 400Gbps 100-piece-FPGA implementation, we investigate performance of the potential FEC schemes for OIF-800GZR. By comparing the power dissipation and correction threshold at 10−15 BER, we proposed the simplified OFEC for the 800G-ZR FEC.
