Erbium Doped Fiber AstroGain™
Fibercore’s new AstroGain™ erbiumdoped fibers are designed for use in space applications, including amplifiersfor inter-satellite communications and light sources for earth monitoringmissions. The fiber is available in two variants, AG980H and AG980L. AG980H hasa unique trivalent core matrix optimized for high continuous operating time, asmight be required in fiber optic gyroscopes. The AG980L has been designed forlower duty cycle operation where intermittent use is expected, as might berequired in earth monitoring missions. These fibers build on Fibercore’sWorld-class erbium doped fiber expertise to deliver new technology tochallenging 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-opticalpower conversion
· High-reliability mechanical design
TypicalApplications:
· Amplifiers for inter-satellite communications
· Light sources for earth observation missions
· Light sources and amplifiers for large scale sensingmissions
