Laser Communication at ViaLight

Optical Network above the Clouds

  • Data rates up to 10Gbps
  • Low SWaP, <10kg
  • Competitive price for terminals in LEO

Today’s Business at ViaLight

  • Stratospheric inter-platform links

with large commercial customers

  • Industrial manufacturing approach

for larger series

  • Path towards large constellations of small

satellites

Inter-HAP Inter-Sat LEO-Ground
