Abstract

Real-time 10,000 km transmission over a straight-line link is achieved using a software-defined multi-modulation format receiver implemented on a commercial off-the-shelf general-purpose graphics processing unit (GPU). Minimum phase 1 GBaud 4-ary quadrature amplitude modulation (QAM) signals are transmitted over 10,000 km and successfully received after detection with a Kramers-Kronig (KK) coherent receiver. 8-, 16-, 32-, and 64-QAM are successfully transmitted over 7600, 5600, 3600, and 1600 km, respectively., Comment: Accepted for publication at Photonics Technology Letters

Abstract

Real-time operation of a software-defined, GPU-based optical receiver is demonstrated over a 100-span straight-line optical link. Performance of minimum-phase Kramers-Kronig 4-, 8-, 16-, 32-, and 64-QAM signals are evaluated at various distances., Comment: Accepted for presentation at the Optical Fiber Communication Conference (OFC) 2021, 6-10 June 2021

Abstract

We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible receiver is able to process 2 GBaud 2-, 4-, 8-, and 16-ary pulse-amplitude modulation (PAM) signals as well as 1 GBaud 4-, 16- and 64-ary quadrature amplitude modulation (QAM) signals, with the latter detected using a Kramers-Kronig (KK) coherent receiver. Experimental performance evaluation is shown for back-to-back. In addition, by using the JGN high speed R&D network testbed, performance is evaluated after transmission over 91 km field-deployed optical fiber and reconfigurable optical add-drop multiplexers (ROADMs)., Comment: Accepted for publication at Journal of Lightwave Technology, already available via JLT Early Access, see supplied DOI.

4. Real-Time Optical Transmission with GPU-Based DSP

Author

van der Heide, Sjoerd, Luis, Ruben S., Puttnam, Benjamin J., Rademacher, Georg, Koonen, Ton, Shinada, Satoshi, Awaji, Yohinari, Furukawa, Hideaki, Okonkwo, Chigo, Electro-Optical Communication, High Capacity Optical Transmission, and Electrical Engineering

Abstract

A real-time receiver with GPU-based digital signal processing is demonstrated using only commercial off-the-shelf equipment. Both intensity-modulated directly-detected PAM-N signals are supported as well as minimum-phase N-QAM signals using Kramers-Kronig coherent detection.
