Space-Qualified EDFA for CubeSat
In 2026, a leading aerospace company and a renowned research institute successfully demonstrated free‑space optical communication between a LEO satellite and ground station using our space-qualified EDFA for CubeSat.
Available in both 2‑in‑1 (Pre‑amplifier + Booster) and Booster‑only versions, these space‑qualified modules are miniaturized to meet CubeSat size and weight constraints. Design qualified through rigorous testing, they deliver high output power with optimal efficiency, low noise, and proven reliability—empowering next‑generation optical communication payloads in compact satellite platforms. Optional full space acceptance testing service is available at extra cost.
