HP EDFA Module for Free Space Communication Application

Amonics' HP (high power) EDFA module series offers eye-safe, single mode, single mode (linear polarized) fiber amplifier. The module can be applied to laser link among satellites in low-Earth orbit. It offers advantages over radio frequencies for ground station-to-satellite and inter-satellite links above the atmosphere: higher transmission bandwidth, smaller receivers, and tighter beams to enhance security. The HP EDFA module series is maintenance free with no post-installation service required. It is a versatile, ready-to-use and durable laser source for various free space communication applications as well as integration to OEM system.
