AVAGO AFBR

AFBR-1529Z
DC to 10 Mbd Versatile Link Fiber Optic
Analog Transmitter for 1 mm POF and 200 µm PCS
Data Sheet
Description
Features
The AFBR-1529Z analog transmitter utilizes a 650 nm LED
source in a housing designed to efficiently couple into
1 mm Polymer Optical Fiber (POF) and 200 µm diameter
Plastic-Clad Silica (PCS). Links up to 50 m are supported
with 1 mm POF, and up to 200 m with 200 µm PCS. It is
designed to interoperate with Avago´s HFBR-25xxZ, AFBR-25xxZ and AFBR-26xxZ receivers.
• RoHS-compliant
The transmitter 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. Please contact Avago
Technologies for details or visit our company website at
www.avagotech.com
• Data transmission at signal rates from DC up to 10 MBd
• Up to 50 meters distance with 1 mm Plastic Optical
Fiber (POF) and 200 meters with 200 µm PCS
• Operating temperature range of -40 °C to +85 °C
• Compatible with Avago’s Versatile Link family of
connectors, for easy termination of fiber
Applications
• Industrial control and factory automation
• Serial field buses
• Intra-system links; Board-to-Board, Rack-to-Rack
• Extension of RS-232 and RS-485
• High voltage isolation
• Elimination of ground loops
• Reduces voltage transient susceptibility
Package and Handling Information
Handling
The Versatile Link package is made of a flame retardant
VALOX1 UL 94 V-0 material and uses the same pad
layout as a standard, eight pin dual-in-line 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.
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).
Non-halogenated water soluble fluxes (i.e., 0% chloride),
not rosin based fluxes, are recommended for use with
Versatile Link components.
Package Housing Color
Versatile Link components and simplex connectors are
color coded to eliminate confusion when making connections. Receivers are black and transmitters are grey.
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.
Interlocked (Stacked) Assemblies (refer to Figure 4)
2.03
(0.080)
Horizontal packages may be stacked by placing units
with pins facing upward. Initially engage the inter-locking
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.

This is an inverting circuitry, thus the

an inverting receiver, e.g. AFBR-2529Z,
