SES has teamed up with French photonics specialist Cailabs to carry out trials of new optical ground stations, according to the companies’ joint announcement. The initiative aims to explore how laser technology can enhance space-to-Earth data links, moving beyond traditional radio frequency systems.

The ground stations, named TILBA-OGS L10, are designed for bidirectional optical connectivity with transfer speeds of up to 10 gigabits per second. SES mentioned that these stations will be remotely operated, making them suitable as gateways within its satellite infrastructure.

A key challenge in optical communications is the distortion caused by atmospheric turbulence. Cailabs noted that its Multi-Plane Light Conversion (MPLC) technology compensates for these effects in real time, maintaining signal quality even under difficult conditions.

SES stated that laser communications offer greater bandwidth, improved security, and reduced interference risks compared to conventional radio systems. Meanwhile, Cailabs highlighted that its stations have already been validated with several satellites and optical terminals, demonstrating their ability to perform reliably in demanding environments.

The companies said the upcoming tests will help determine how optical ground systems can be integrated into SES’s broader satellite operations, potentially setting the stage for more widespread adoption of laser communication in the future.
