DESCRIPTION
The HFE4050-01X/XXX is a high radiance GaAlAs
850 nanometer LED optimized for coupling into small
fiber core diameters at a forward current up to 100 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.
APPLICATION
The HFE4050-01X/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 above 85 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 HFE4050-01X/XXX LED provides the maximum
amount of radiance for the amount of forward current in
the industry. A 0.25 mm diameter glass microlens over
the "Caprock"™ junction collimates the light, increasing
the intensity. Thus, greater power is directed toward
standard fiber optic cables.

Notes
1. Dash numbers indicate power output. See ORDER GUIDE.
2. HFE4050-01X/XXX is tested using a 10 meter length of 50/125 µm dia. fiber cable, terminated in a precision ST ferrule. Actual
coupled power values may vary due to alignment procedures and/or receptacle and fiber tolerances.
3. HFE4050-01X/XXX must be heat sinked for continuous I¸ > 100 mA operation for maximum reliability (i.e. mounted in a metal
connector with thermally conductive epoxy).

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.

Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of time may affect
reliability.
