De scrip tion

The OPF340 series LED provides fiber

optic users with high coupled power and

wide bandwidth in an easily mounted

package.

The LED’s are designed to interface with

multimode optical fibers from 50/125 to

200/300 microns.

Notes:

(1) RMA flux is recommended. 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's are subject to 100% burn-in testing. Test conditions are 96 hours at 100 mA

continuous current in 25o C ambient.
