Avionics, Military Datacom

810nm

High-Performance LED

This high speed device is optimized

at 810 nm wavelength which is of

particular interest for use in radia-

tion-hardened fiber. It operates in a

wide temperature range and delivers

very high power to 200 µm core fiber,

making it ideal in avionics and mili-

tary datacom applications.
