Overview

Randomized trial shows enhanced data rates in optical wireless systems, indicating scalable data center solutions.

Key Points

  • This work aims to improve data transfer rates in optical wireless communication systems for data centers.
  • Co-design of transceiver front ends and packaging interfaces.
  • Use of nonlinear equalization algorithms to enhance channel performance.
  • Experimental demonstration of a four-channel transceiver module over a 50 cm free-space link.
  • Achieved 100 Gb/s NRZ and 160 Gb/s PAM-4 data rates per channel, totaling 640 Gb/s aggregate.
  • First multi-channel IM/DD OWC system attaining performance comparable to wired solutions.
  • Demonstrated effective elimination of impedance discontinuity and reduced nonlinear intersymbol interference.
