www U.coDESCRIPTION
The HFD3026 is a 35 MHz fiber optic analog receiver
t4with an on-chip voltage regulator to assure improved
noise immunity. The linear output voltage swing is
inverted from the optical input, and proportional to the
eoptical input power levels between 0.5 µW and 100 µW. It
has an equivalent circular active diameter of 0.020 inch.
eThe HFD3026 is supplied in a Honeywell plastic package,
and can be mounted in several types of fiber optic
hconnectors. Companion optical LEDs are available.
OPERATION
SThe HFD3026 fiber optic analog receiver has on-chip
voltage regulation which requires an external 0.1 µF
tabypass capacitor. This capacitor should be connected
between pin # 1 (bypass capacitor) and pin 4 (ground).
Noise immunity is enhanced by keeping lead lengths as
short as possible. The output has a linear voltage swing
aproportional to the optical power striking the photodiode
between input luminance of 0.5 µW and 100 µW .
Guaranteed minimum response is 4 mV/µW, which
.Dprovides 2.0 mV output for 0.5 µW input.
mFor standard electrical loads, a post-amplifier should be
oused with the HFD3026. When a load capacitance of
w .c3 pF or more is encountered, a 330 í resistance in
series with the output is required to minimize ringing of
Uthe output signal. This provides an excellent electrical
w t4signal for the system designer. The HFD3026-012 has a
500 í output drive capability for higher load applications.

This package is also available in special interface receptacles for
interfacing to standard fiber optic cables.
CAUTION
The inherent design of this component causes
it to be sensitive to electrostatic discharge
(ESD). To prevent ESD-induced damage
and/or degradation to equipment, take normal
ESD precautions when handling this product.
FIBER INTERFACE
Honeywell detectors are designed to interface with
multimode fibers with sizes (core/cladding diameters)
ranging from 50/125 to 200/230 microns. Honeywell
performs final tests using 100/140 micron core fiber. The
fiber chosen by the end user will depend upon a number
of application issues (distance, link budget, cable
attenuation, splice attenuation, and safety margin). The
50/125 and 62.5/125 micron fibers have the advantages
of high bandwidth and low cost, making them ideal for
higher bandwidth installations. The use of 100/140 and
200/230 micron core fibers results in greater power being
coupled by the transmitter, making it easier to splice or
connect in bulkhead areas. Optical cables can be
purchased from a number of sources.
