AFBR-16xxZ and AFBR-26x4Z/25x9Z
DC-50MBd Versatile Link Fiber Optic Transmitter
and Receiver for 1 mm POF and 200 m PCS
Data Sheet
Description
Features
The AFBR-16xxZ transmitter utilizes a 650 nm LED source
with integrated optics and driver IC for efficient coupling
into 1 mm Polymer Optical Fiber (POF). The AFBR26x4Z/25x9Z receiver consists of an IC with an integrated
photodiode to produce a logic compatible output. The
transmitter input and receiver output are compatible with
TTL logic families. The pair operates any type of signal
from DC up to 50 MBd at distances up to 50 m with 1 mm
POF, up to 200 m at 10 MBd and 120 m at 50 MBd with 200
m Plastic-Clad Silica (PCS), respectively.
RoHS-compliant
The transmitter is a 3-pin and the receiver is a 4-pin device,
packed in Versatile Link housing. Versatile Link components can be interlocked (N-plexed together) to minimize
space and to provide dual connections with the duplex
connectors. Various simplex and duplex connectors, as
well as POF cables are available for Versatile Link components. For details, contact Avago Technologies or visit our
company website at www.avagotech.com
AFBR-xxx4Z are delivering non-inverted output signals
while AFBR-xxx9Z deliver inverted output signals.

Application Literature
Handling
Application Note 1035 (Versatile Link) - AV02-0730EN
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.
Package and Handling Information
The compact Versatile Link package is made of a flameretardant material and uses the same pad layout as a
standard, eight-pin dual-in-line package. Horizontal,
Vertical, and Tilted (30°) packages 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 Orientation
Performance and pinouts for the horizontal, vertical, and
tilted (30°) 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. Receiver packages are black and transmitter
packages are gray in color respectively.
2
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 soldering
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.
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.

NOTES:
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.

4. Pulse width is measured at 50% threshold using a rising edge trigger tested with PRBS-7 pattern
5. Electrical input pulse width is determined at 1.5 V and dU/dt between 1 V and 2 V shall not be less than 1 V/ns.
6. The first pulse is shorter as the LED is completely discharged. This helps to mitigate the increase of pulse width of the first pulse of the Receiver
