Duration can be extended to 10 sec. max when flow soldering. (2) Graded index fiber, 50 µm core, N.A. = 0.20. (3) To convert radiant power output to dBm, use the following expression: dBm = 10 log (µW/1000). (4) Derate linearly @ 1.0 mA/o C above 25o C. (5) Prebias @ 5 mA current. LED Burn-in All LED’ are subject to 100% burn-in testing. Test conditions are 96 hours at 100 mA s continuous current in 25o C ambient. Description The OPF395 series LED provides fiber optic users with high coupled power and wide bandwidth in a low cost package. The LED’ are designed to interface with s multimode optical fibers from 50/125 to 200/300 microns. TYPICAL COUPLED POWER into OPTICAL FIBER Typical Coupled Power o IF = 100 mA @ 25 C N.A.
