Description
The Versatile Link series is a
complete family of fiber optic link
components for applications
requiring a low cost solution. The
HFBR-0501 series includes trans-
mitters, receivers, connectors and
cable specified for easy design.
This series of components is ideal
for solving problems with voltage
isolation/insulation, EMI/RFI
immunity or data security. The
optical link design is simplified
by the logic compatible receivers
and complete specifications for
each component. The key optical
and electrical parameters of links
configured with the HFBR-0501
family are fully guaranteed from
0
°
to 70
°
C.
A wide variety of package config-
urations and connectors provide
the designer with numerous
mechanical solutions to meet
application requirements. The
transmitter and receiver compo-
nents have been designed for use
in high volume/low cost assembly
processes such as auto insertion
and wave soldering.
Transmitters incorporate a 660
nm LED. Receivers include a
monolithic dc coupled, digital IC
receiver with open collector
Schottky output transistor. An
internal pullup resistor is avail-
able for use in the HFBR-25X1/2/
4 receivers. A shield has been
integrated into the receiver IC to
provide additional, localized noise
immunity.
Internal optics have been optim-
ized for use with 1 mm diameter
plastic optical fiber. Versatile
Link specifications incorporate
all connector interface losses.
Therefore, optical calculations for
common link applications are
simplified.
