DESCRIPTION
The HFE4003-02X/XXX is a high radiance GaAlAs
850 nanometer LED optimized for coupling into small
fiber core diameters at a forward current of 5 to 50 mA.
The patented "Caprock"™ LED chip combines high power
coupling with wide bandwidth. The peak wavelength is
matched for use with Honeywell silicon fiber optic
detectors and receivers. When the HFE4003-02X/XXX is
used at elevated temperatures, thermal resistance must
be taken into consideration.
APPLICATION
The HFE4003-02X/XXX is a high radiance LED
packaged in a fiber optic connector that aligns the optical
axis of the base component to the axis of the optical fiber.
Data rates can vary from DC to 150 MHz depending upon
component application. The LED converts electrical
current into optical power that can be used in fiber optic
communications. As the current varies (typically from 10
to 100 mA), the light intensity increases proportionally.
The HFE4003-02X/XXX LED provides high fiber coupled
power (high radiance into a standard fiber optic cable). A
0.30 mm diameter glass microlens is placed over the
"Caprock"™ junction. The microlens collimates the light,
increasing the intensity directed toward a fiber optic
cable. The "SWEET SPOT" of power sends greater
power into standard fiber optic cables.
Honeywell reserves the right to make
changes in order to improve design and
supply the best products possible.

FIBER INTERFACE
Honeywell LEDs are designed to interface with
multimode fiber with sizes ranging from 50/125 to
200/230 microns. Honeywell performs final tests using
50/125 micron core fiber. All multimode fiber optic cables
between 50/125 and 200/230 should operate with similar
excellent performance. See table for typical powers.
