AFBR-T524Z/AFBR-R524Z
50 Megabaud Versatile Link Fiber Optic Transmitter
and Receiver for 1mm POF
Data Sheet
Description
Features
The AFBR-T524Z transmitter utilizes a 650nm LED source
with integrated optics and driver IC for efficient coupling
into 1mm Polymer Optical Fiber (POF). The AFBR-R524Z
receiver incorporates a PIN detector and digital output IC.
The transmitter input and receiver output are compatible
with TTL logic families. The pair operates up to 50MBd at
distances up to 50 meters with 1mm POF using bi-phase
encoding scheme.
•ꢀ RoHS-compliant
•ꢀ Data transmission at signal rates up to 50MBd
•ꢀ Transmitter: integrated 650nm LED and driver IC with
TTL input logic
•ꢀ Receiver: integrated PIN diode and digitalizing IC with
TTL output logic
•ꢀ Up to 50 meters distance with 1mm Plastic Optical
Fiber (POF)
The transmitter is a 3-pin and the receiver is a 4-pin device,
packed in Versatile Link housing. Versatile Link compo-
nents 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 compo-
nents. Please contact Avago Technologies for details or
visit our company website at www.avagotech.com.

Package and Handling Information
Interlocked (Stacked) Assemblies (refer to Figure 1)
The Versatile Link package is made of a flame retardant Horizontal packages may be stacked by placing units
1
VALOX UL 94 V-0 material (UL file # E121562) and uses with pins facing upward. Initially engage the inter-locking
the same pad layout as a standard, eight pin dual-in-line mechanism by sliding the L bracket body from above into
package. These 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.
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 disen-
gaged if necessary. Repeated stacking and unstacking
causes no damage to individual units.
Package Housing Color
Versatile Link components and simplex connectors are
color coded to eliminate confusion when making connec-
tions. Receivers are black and transmitters are grey.
Stacking Horizontal Modules
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 contami-
nation of the port. Do not use reflow solder processes (i.e.,
infrared reflow or vapor-phase reflow). Non-halogenated
water soluble fluxes (i.e., 0% chloride), not rosin based
fluxes, are recommended for use with Versatile Link
components.
Versatile Link components are moisture sensitive devices
and are shipped in a moisture sealed bag. If the compo-
nents 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 halo-
genated hydrocarbons because of their potential environ-
mental harm.

1. Logic 1 input will turn the light on and the logic 0 will turn the light off.
2. TTL compatible data output.
3. Pin 5 and 8 are for mounting and retaining purposes, but are electrically connected.
4. It is recommended to connect this pin to ground to reduce coupling of electrical noise.
5. POF is HFBR-R/EXXYYYZ plastic (1 mm) optical fiber. Worst case attenuation used (0.23 dB/m for extra low loss POF and 0.27dB/m for standard loss
POF cable from 0°C to +85°C at 660 nm).
