Fiber Optic GaAlAs High Speed LED
Types OPF345A, OPF345B, OPF345C, OPF345D
Features
• High radiant output for fiber optic
applications
• High speed
• Electrically isolated from case
Description
The OPF345 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 25^o 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.
