Fiber Optic GaAlAs High Speed LED
Types OPF340A, OPF340B, OPF340C, OPF340D
Features
High radiant output for fiber optic
applications
High speed
Electrically isolated from case
Description
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.
