Features

•Electrically isolated plastic cap

package

•High radiant output for fiber optic

applications

•High speed

•Designed to self align in the 0.228

inch diameter bore of standard fiber

optic receptacles. Press fit simplifies

component installation.

Description

The OPF390 series LED provides fiber

optic users with high coupled power and

wide bandwidth in a low cost 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 25

o C ambient.
