Fiber Optic GaAlAs LED in SMA Receptacle

Types OPF321A, OPF321B, OPF321C

Features

• Component pre-mounted and ready

to use

• Pre-tested with fiber to assure

performance

• Popular SMA style receptacle

Description

The OPF321 series LED consists of a

hermetic 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

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, 50µm 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/oC 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.
