Overview

Compared with traditional RF systems, laser communication offers markedly higher bandwidth, lower power consumption, and superior anti-interference and security. It is well-suited to large constellations, Earth observation, deep-space exploration, and secure/quantum communications.

The portfolio spans high-precision optical assemblies, inter-satellite and satellite-to-ground laser terminals, and a comprehensive ground far-field equivalent test system—forming a complete end-to-end solution.
