Erbium Doped Fiber AstroGain™
Fibercore’s new AstroGain™ erbium doped fibers are designed for use in space applications, including amplifiers for inter-satellite communications and light sources for earth monitoring missions. The fiber is available in two variants, AG980H and AG980L. AG980H has a unique trivalent core matrix optimized for high continuous operating time, as might be required in fiber optic gyroscopes. The AG980L has been designed for lower duty cycle operation where intermittent use is expected, as might be required in earth monitoring missions. These fibers build on Fibercore’s World-class erbium doped fiber expertise to deliver new technology to challenging environments.
- AG980H for high duty cycle space applications
- AG980L for low duty cycle space applications
- Optimized trivalent core matrix for space operation
- High-efficiency designs for maximum electrical-to-optical power conversion
- High-reliability mechanical design
Typical Applications:
- Amplifiers for inter-satellite communications
- Light sources for earth observation missions
- Light sources and amplifiers for large scale sensing missions
