2-in-1 EDFA Module for HAPS
Our 2‑in‑1 EDFA modules, combining pre‑amplifier and booster amplifier, are engineered for reliable optical communication in stratospheric environments. Miniaturized to meet strict size and weight constraints, they integrate seamlessly into compact high‑altitude systems. Delivering up to 5W output power with optimal efficiency and low noise figure, these modules ensure robust performance for next‑generation High‑Altitude Platform Stations (HAPS). Designed for durability and precision, they empower advanced communication payloads, enabling dependable connectivity in challenging atmospheric conditions.
