Fiber Optic GaAlAs LED in SMA Receptacle
Types OPF371A, OPF371B, OPF371C, OPF371D
Features
• Component pre-mounted and ready
to use
• Pre-tested with fiber to assure
performance
• Popular SMA style receptacle
Description
The OPF371 series LED consists of a
low cost plastic cap LED, pre-mounted
and aligned in an SMA receptacle. This
configuration is designed for PC board
or panel mounting. Includes lock washer
and jam nut, two 2-56 screws, and a dust
cap.
The LED’s are designed to interface with
mulitmode 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.
