Operational optical communications, at scale.

Cailabs builds the ground systems that make laser communications deployable.

The next bottleneck is on the ground

Satellite and defense networks are moving toward higher-capacity, lower-signature optical links. The challenge is no longer only to prove laser communications, but to deploy the ground infrastructure that will make them operational at scale.

Cailabs is building an Optical Ground Network

Built for operation

 

Cailabs engineers ground systems for real-world deployment, integration into existing networks, remote operation and scalable rollouts. We make laser communications reliable, taskable on-demand, as routine as radio, not just one-shot demos in controlled demonstrations.

Assembly And Validation Platform Cailabs

Bringing optical connectivity down to Earth, seamlessly.

Cailabs delivers infrastructure-grade optical connectivity at 10+ Gbps, fully compatible with existing standards and terminals.

Proven execution, built to scale

Cailabs is turning optical communications into deployable ground infrastructure. From first deployments to repeatable rollouts, Cailabs combines field-proven performance, manufacturing capability and operational support.

The same engineering discipline, across photonics

Beyond laser communications, Cailabs applies its light-shaping expertise to idustrial laser processing and fiber networks, where performance, reliability and deployability matter just as much. Our products are built from the same foundation: advanced control of light, transformed into robust systems for demanding industrial and communication environments.
