DESCRIPTION
The HFD3000-002/XXX is a sensitive differentiating
optical receiver designed for use in short distance,
850 nm fiber optic systems. The receiver uses a hybrid
construction consisting of a PIN photodiode, bipolar
integrated receiver circuit with internal voltage regulation
and internal bypass capacitor. The TTL output allows it
to be directly interfaced with standard digital TTL circuits.
The HFD3000-002/XXX consists of a base fiber optic
component (HFD3000) which is mounted in a fiber optic
connector that aligns the optical axis of the base
component to the axis of the optical fiber.
APPLICATION
The HFD3000-002/XXX optical receiver converts the
optical signal in a point to point data communications
fiber optic link to a TTL output.
Electrical isolation is important in obtaining the maximum
performance of this high sensitivity receiver. Shielding
can reduce coupled noise and allow maximum sensitivity
to be obtained. This can include the use of ground planes
in the PCB, shielding around the device, and shielding
around the leads.
The maximum temperature of 100¡C allows the
HFD3000-002/XXX to be designed into a broad variety of
applications.
Honeywell also offers companion transmitters designed
to operate in conjunction with the HFD3000-002/XXX.
