Description
Features
The Versatile Link series is a complete family of fiber • Low cost fiber optic components
optic link components for applications requiring a low
cost solution. The HFBR-0501 series includes
transmitters, receivers, connectors and cable specified
for easy design. This series of components is ideal for
solving problems with voltage isolation/insulation,
EMI/RFIimmunityordata security. The opticallinkdesign
is simplified by the logic compatible receivers and
complete specifications for each component. The key
opticaland electricalparameters oflinks configured with
the HFBR-0501 family are fully guaranteed from 0° to
70°C.
• Enhanced digital links dc-5 MBd
• Extended distance links up to 120 m at 40 kBd
• Low current link: 6 mA peak supply current
• Horizontal and vertical mounting
• Interlocking feature
• High noise immunity
• Easy connectoring Simplex, Duplex, and Latching
connectors
• Flame retardant
• Transmitters incorporate a 660 nm Red LED for easy
visibility
Awide varietyofpackage configurations and connectors
provide the designerwith numerousmechanicalsolutions
to meet application requirements. The transmitter and
receivercomponents have been designed foruse in high
volume/low cost assembly processes such as auto
insertion and wave soldering.
• Compatible with standard TTL circuitry
Applications
• Reduction of lightning/voltage transient susceptibility
• Motor controller triggering
• Data communications and local area networks
• Electromagnetic Compatibility (EMC) for regulated
systems: FCC, VDE, CSA, etc.
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-25X1/2/4
• Tempest-secure data processing equipment
receivers. A shield has been integrated into the receiver • Isolation in test and measurement instruments
IC to provide additional, localized noise immunity.
• Error free signalling for industrial and manufacturing
equipment
Internal optics have been optimized for use with 1 mm
diameterplasticopticalfiber.Versatile Linkspecifications
incorporate all connector interface losses. Therefore,
optical calculations for common link applications are
simplified.
• Automotive communications and control networks
• Noise immune communication in audio and video
equipment

Application Literature
Application Note 1035 (Versatile Link)
Package Orientation
Package and Handling Information
Performance and pinouts for the vertical and horizontal
packagesare identical.To provide additionalattachment
support for the vertical Versatile Link housing, the
designer has the option of using a self-tapping screw
through a printed circuit board into a mounting hole at
the bottom of the package. For most applications this is
not necessary.
The compact Versatile Link package is made of a flame
retardant VALOX UL 94 V-0 material (UL file # E121562)
®
and uses the same pad layout as a standard, eight pin
dual-in-line package. Vertical and horizontal mountable
parts are available. These low profile Versatile Link
packages are stackable and are enclosed to provide a
dust resistant seal. Snap action simplex, simplex
latching, duplex, and duplex latching connectors are
offered with simplex or duplex cables.
Package Housing Color
Versatile Link components and simplex connectors are
color coded to eliminate confusion when making
connections. Receivers are blue and transmitters are
gray, except for the HFBR-15X3 transmitter, which is
black.

Interlocked (Stacked) Assemblies (refer to Figure 1)
To stack vertical packages, hold one unit in each hand,
with the pins facing away and the optical ports on the
bottom. Slide the L bracket unit into the L slot unit. The
straight edge used for horizontal package alignment is
not needed.
Horizontal packages may be stacked by placing units
with pins facing upward. Initially engage the inter-
locking mechanism by sliding the L bracket body from
above into the L slot body of the lower package. Use a
straight edge, such as a ruler, to bring all stacked units
into uniform alignment. This technique prevents
potential harm that could occur to fingers and hands of
assemblers from the package pins. Stacked horizontal
packages can be disengaged if necessary. Repeated
stacking and unstacking causes no damage to individual
units.

2. Optical power, P (dBm) = 10 Log [P(µW)/1000 µW].
3. Rise and fall times are measured with a voltage pulse driving the transmitter and a series connected 50 Ω load. A wide bandwidth optical to
electrical waveform analyzer, terminated to a 50 Ω input of a wide bandwidth oscilloscope, is used for this response time measurement.

Notes:
1. Measured at the end of the fiber optic cable with large area detector.
2. Optical flux, P (dBm) = 10 Log P(µW)/1000 µW.
3. Because of the very high sensitivity of the HFBR-25X3, the digital output may switch in response to ambient light levels when a cable is not
occupying the receiver optical port. The designer should take care to filter out signals from this source if they pose a hazard to the system.
4. Including current in 3.3 k pull-up resistor.
