Description
The Versatile Link ries is a
complete family of fiber optic link
components for applications
requiring a low cost solution. The
HFBR-0501 ries includes trans-
mitters, receivers, connectors and
cable specified for easy design.
This ries of components is ideal
for solving problems with voltage
isolation/insulation, EMI/RFI
immunity or data curity. 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 u
in high volume/low cost asmbly
process such as auto inrtion
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 u in the HFBR-25X1/2/
4 receivers. A shield has been
因地制宜的意思integrated into the receiver IC to
provide additional, localized noi
immunity.
Internal optics have been optim-
ized for u with 1 mm diameter
plastic optical fiber. Versatile
Link specifications incorporate
all connector interface loss.
Therefore, optical calculations for
common link applications are
simplified.

Application Note 1035 (Versatile Link)
VALOX ® is a registered trademark of the General Electric Corporation.
Package and Handling Information
The compact Versatile Link pack-age is made of a flame retardant VALOX ® UL 94 V-0 material
(UL file # E121562) and us the same pad layout as a standard,eight pin dual-in-line package.Vertical and horizontal mountable parts are available. The low profile Versatile Link packages are stackable and are enclod to
provide a dust resistant al.Snap action simplex, simplex latching, duplex, and duplex latching connectors are offered with simplex or duplex cables.Package Orientation
Performance and pinouts for the vertical and horizontal packages are identical. To provide addi-tional attachment support for the vertical Versatile Link housing,
the designer has the option of using a lf-tapping 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 transmit-ters are gray, except for the
HFBR-15X3 transmitter, which is black.
Handling
Versatile Link components are auto-inrtable. 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 u reflow solder process (i.e., infrared reflow or vapor-pha reflow).
Nonhalogenated water soluble fluxes (i.e., 0% chloride), not rosin bad fluxes, are recom-mended for u with Versatile Link components.
Versatile Link components are moisture nsitive devices and are shipped in a moisture aled bag. If the components are expod 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.

Alcohols: methyl, isopropyl,isobutyl. Aliphatics: hexane,heptane, Other: soap solution,naphtha.wps很卡
Do not u 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 u of cleaners that u halogenated hydrocarbons becau of their potential environmental harm.

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 asmblers from the package pins. Stacked horizontal packages can be dingaged if necessary.Repeated stacking and unstack-ing caus 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 ud for
horizontal package alignment is not needed.

Notes:
1. The propagation delay for one metre of cable is typically 5 ns.
2. Typical propagation delay is measured at P R = -15 dBm.
3. Estimated typical link life expectancy at 40°C exceeds 10 years at 60 mA.
