DESCRIPTION

The HFD3023-002/XXX is a sensitive Direct Coupled

(DC) optical receiver designed for use in short distance,

850 nm fiber optic systems. The receiver contains a

monolithic IC, consisting of a photodiode, DC amplifier,

and open collector Schottky output transistor. The output

allows it to be directly interfaced with standard TTL

circuits. The HFD3023-002/XXX receiver is comprised of

a HFD3023 receiver component packaged in a fiber optic

connector.

APPLICATION

The HFD3023-002/XXX fiber optic receiver converts the

optical signal in a point to point data communications

fiber optic link to a TTL output. Its 0.006 in. photodiode

with a 0.024 in. microlens (to enhance the optics) is

mechanically centered within the fiber optic connector.

Electrical isolation is important in obtaining the maximum

performance. A 0.1 µF bypass capacitor must be

connected between VÙÙ and ground. This minimizes

power supply noise, increasing the signal quality.

Shielding can also reduce coupled noise, through use of

ground plane PCB, shielding around the device, and

shielding around the leads.

The HFD3023-002/XXX is designed for a wide optical

input range. The optical input dynamic range is

guaranteed from the maximum sensitivity of 3.0 µW to

100 µW or greater than 15 dB.

Honeywell reserves the right to make

changes in order to improve design and

supply the best products possible.

APPLICATION (continued)

Optical power from the fiber strikes the photodiode and

is converted to electrical current. This current couples to

the DC amplifier, which drives an open collector

transistor output. The output when connected to a pull

up resistor can interface to TTL loads. The electrical

signal is the inverse of the input light signal. When light

strikes the photodiode, the output is a low logic level.

When no light strikes the photodiode, the output is a

high logic level.

Pulse Width Distortion (PWD) is an increase in the

output pulse width (for high level optical input). The

typical performance curves illustrate how PWD varies

with optical power, temperature and frequency for the

HFD3023-002/XXX. The amount of PWD that a given

system can tolerate without an error due to a missing bit

of information, is dependent upon system

considerations. The output of the HFD3023-002/XXX will

typically connect to the input of some form of a serial

interface adaptor IC. The specifications for that IC

govern the amount of PWD that can be tolerated in the

system.

ORDER GUIDE

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.
