Description
transmitter and receiver compo-
nents have been designed for use
in high volume/low cost assembly
processes such as auto insertion
and wave soldering.
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.
• 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 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.
• Transmitters Incorporate a
660 nm Red LED for Easy
Visibility
• Compatible with Standard
TTL Circuitry
Applications
• Reduction of Lightning/Volt-
age Transient Susceptibility
• Motor Controller Triggering
• Data Communications and
Local Area Networks
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.
• Electromagnetic
Compatibility (EMC) for
Regulated Systems: FCC,
VDE, CSA, etc.
• Tempest-Secure Data
Processing Equipment
A wide variety of package config-
urations and connectors provide
the designer with numerous
mechanical solutions to meet
application requirements. The

the designer has the option of
using a self-tapping screw

into a mounting hole at the
bottom of the package. For most
applications this is not necessary.
Information
The compact Versatile Link pack-
age 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

tional attachment support for the

when making connections.
Receivers are blue and transmit-
ters are gray, except for the
HFBR-15X3 transmitter, which is
black.
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.
Recommended Chemicals for
Cleaning/Degreasing
Alcohols: methyl, isopropyl,
isobutyl. Aliphatics: hexane,
heptane, Other: soap solution,
naphtha.
Handling
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 recom-
mended for use with Versatile
Link components.
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, Agilent
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.

Humidity (RH).
2. After this bag is opened, devices that will be subjected to wave

10 sec) must be:
a) Mounted within 72 hours at factory conditions of ≤ 30°C/60% RH.
b) Stored at ≤ 20% RH.
3. Devices require baking, before mounting, if:
a) Desiccant changes to PINK.

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.
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
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 unstack-
ing causes no damage to
individual units.

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.
