AFBR-1644Z and AFBR-2644Z DC, 50 Megabaud Versatile Link Fiber Optic Transmitter and Receiver for 1 mm POF Data Sheet Description Features The AFBR-1644Z transmitter utilizes a 650 nm LED source with integrated optics and driver IC for efficient coupling into 1 mm Polymer Optical Fiber (POF). The AFBR-2644Z 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 meters with 1 mm POF. The AFBR-xx44Z deliver non inverted output signals. 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. Initially engage the inter-locking mechanism by sliding the L bracket body from above into the L slot body of the lower package. 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 connections. Receivers are black and transmitters are grey. 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. 2 VALOX is a registered trademark of the General Electric Company. Figure 1.

Measured after 1meter 0.5 NA 1mm POF with polished connector end face. 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 6 AFBR-2644Z Receiver The AFBR-2644Z receiver consists of a digitalizing IC with integrated photodiode to produce an output level that is compatible with TTL logic. The integrated photodiode and the following amplifier uses a fully differential approach with an active and a passive area for an improved EMI performance. Within the specified range the AFBR-2644Z device will support a BER <10E-9.

Standard TTL output. 2. Measured with RL = 50 k and CL = 15 pF 3. Optical Power generated by a standard Avago Technologies Transmitter, with ideal alignment to the photodiode using a 1 mm POF (NA = 0.5). 6. Optical input of 50 MBaud PRBS-7 pattern and 50% duty cycle. 7. Pulse width is measured at 50% threshold using a rising edge trigger and PRBS-7 pattern. 8. If data rate is below 1Mbaud the pulse width distortion would be equal to the pulse width distortion of the 1st to 3rd pulses for higher datarates. 9. The threshold of the 1st pulse of a data sequence is difficult to adjust and therefore the pulse width distortion up to the 3rd pulse is higher than for all other pulses (worst case for the 1st pulse). This strongly depends on the quality of the rising and falling edge of the optical input. The faster the edges the smaller the pulse width variation. Furthermore lower data rates would result in the same issue as all the pulse become 1st pulses. 10. Output low for AFBR-2644Z.
