HFBR-0500Z Series
Versatile Link
The Versatile Fiber Optic Connection
Data Sheet
Description
The Versatile Link series is a complete family of fiber
optic link components for applications requiring a low
cost solution. The HFBR-0500Z series includes trans
mitters, receivers, connectors and cable specified for
easy design. This series of compon ents 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 specifi-cations for each component. The
key optical and electrical parameters of links configured
with the HFBR-0500Z family are fully guaranteed from
0° to 70°C.
A wide variety of package configu rations and connectors
provide the designer with numerous mechanical solutions
to meet application requirements. The transmitter and
receiver compon ents have been designed for use in high
volume/low cost assembly processes such as auto inser-
tion 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 available for use in the
HFBR-25X1Z/2Z/4Z receivers. A shield has been in-
tegrated into the receiver IC to provide additional,
localized noise immunity.
Internal optics have been optimized for use with 1 mm di-
ameter plastic optical fiber. Versatile Link specifications in-
corporate all connector interface losses. Therefore, optical
calculations for common link applications are simplified.

Notes:
1. The propagation delay for one metre of cable is typically 5 ns.
2. Typical propagation delay is measured at PR = -15 dBm.
3. Estimated typical link life expectancy at 40 °C exceeds 10 years at 60 mA.
4. Optical link performance is guaranteed only with transmitter HFBR-15x1Z and receiver HFBR-25x1Z.
