HFBR-0500Z Series
Versatile Link
The Versatile Fiber Optic Connection
Data Sheet
Description
Features
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 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 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.
• RoHS-compliant
A wide variety of package configurations and connectors
provide the designer with numerous mechanical solutions
to meet application requirements. The transmitter and
receiver components have been designed for use in high
volume/low cost assembly processes such as auto insertion and wave soldering.
• Flame retardant
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 availa ble for use in the
HFBR-25X1Z/2Z/4Z receivers. A shield has been integrated into the receiver IC to provide additional,
localized noise immunity.
Internal optics have been optimized 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.
• Low cost fiber optic components
• 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
• Transmitters incorporate a 660 nm red LED for easy
visibility
• 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.
• Tempest-secure data processing equipment
• Isolation in test and measurement instruments
• Error free signalling for industrial and manufacturing
equipment
• Automotive communications and control networks
• Noise immune communication in audio and video
equipment

Package and Handling Information
Package Orientation
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.
Performance and pinouts for the vertical and horizontal packages are identical. To provide additional
attachment support for the vertical Versatile Link
housing, the designer has the option of using a selftapping screw through a printed circuit board into a
mounting hole at the bottom of the package. For most
applications this is not necessary.
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-15X3Z transmitter, which is black.
VALOX® is a registered trademark of the General Electric Corporation.

Handling
Recommended Chemicals for Cleaning/Degreasing
Versatile Link components are auto-insertable. When
wave soldering is performed with Versatile Link components, the optical port plug should be left in to prevent
contamination of the port. Do not use reflow solder
processes (i.e., infrared reflow or vapor-phase reflow).
Nonhalogenated water soluble fluxes (i.e., 0% chloride),
not rosin based fluxes, are recommended for use with
Versatile Link components.
Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane,
heptane. Other: soap solution, naphtha.
Versatile Link components are moisture sensitive
devices and are shipped in a moisture sealed bag. If the
components are exposed to air for an extended period of
time, they may require a baking step before the solder
ing process. Refer to the special labeling on the shipping
tube for details.
Do not use partially halogenated hydrocarbons such
as 1,1.1 trichloroethane, ketones such as MEK, acetone,
chloroform, ethyl acetate, methylene dichloride, phenol,
methylene chloride, or N-methylpyrolldone. Also, Avago
does not recommend the use of cleaners that use
halogenated hydrocarbons because of their potential
environmental harm.

Interlocked (Stacked) Assemblies (refer to Figure 1)
Horizontal packages may be stacked by placing units
with pins facing upward. Initially engage the interlocking 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.

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.

1. For IFPK > 80 mA, the duty factor must be such as to keep IFdc ≤80 mA. In addition, for IFPK > 80 mA, the following rules for pulse width apply:
IFPK ≤ 160 mA: Pulse width ≤ 1 ms
IFPK > 160 mA: Pulse width ≤ 1 µS, period ≥20 µS.
2. The propagation delay for one meter of cable is typically 5 ns.
3. Estimated typical link life expectancy at 40 °C exceeds 10 years at 60 mA.
4. Pulsed LED operation at IFPK > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH time contributes to increased
pulse width distortion of the receiver output signal.
5. Optical link performance is guaranteed only with transmitter HFBR-15x2Z/4Z and receiver HFBR-25x2Z/4Z.

1. Measured at the end of the fiber optic cable with large area detector.
2. Pulsed LED operation at IF > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH time contributes to increased pulse
width distortion of the receiver output signal.
3. The LED drive circuit of Figure 11 is required for 1 MBd operation of the HFBR-25X2Z/25X4Z.
4. Optical flux, P (dBm) = 10 Log [P(µW)/1000 µW].
5. RL is open.
6. Guaranteed only if optical input signal to the receiver is generated by HFBR-15x2Z/4Z, with ideal alignment to photodiode using 1 mm POF
(NA=0.5).

2. Optical flux, P (dBm) = 10 Log P(µW)/1000 µW.
3. Because of the very high sensitivity of the HFBR-25X3Z, 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.
