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 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.

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. 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. 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 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. 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. 1.
