On-Board Photonics expands bandwidth and reduces power consumption

As demand for data bandwidth grows, CPO and on-board optics enable a reduction of the power consumption per bit while achieving higher channel densities.

Both concepts are not new per se – in this overview article, featured in photonics spectra, we discuss the concepts of our embedded waveguide technology and how it can be interfaced with other components.

Live Demo in cooperation with COBO at ECOC Basel 2022

vario-optics is a recent member of the multimode waveguide interconnect working group led by COBO (consortium for on-board optics).

Together with COBO we are working on developing novel solutions for increased data-rates and reduced power consumption using photonic technologies.

At ECOC 2022 in Basel we did a live-Demo of our fully-assembled, multimode Electro-Optical Circuit Board:


  • High-Speed electrical design with 20 layers
  • optical waveguide layer in the center containing low-loss multimode waveguides
  • Total on-board throughput of 1.2 TBit/s over 48 optical channels.
