Broadcom AFBR-1639Z

The AFBR-16xxZ transmitter utilizes a 650-nm LED light source, integrated optics, and a driver IC for efficient coupling to 1-mm polymer optical fiber (POF). The AFBR-26x4Z/25x9Z receiver consists of an IC with an integrated photodiode to generate a logic-compatible output. The transmitter input and receiver output are compatible with the TTL logic family. This pair of devices can transmit any type of signal on 1-mm POF at rates from DC to 50 Mbaud over distances up to 50 meters; at 10 Mbaud, the distance can reach 200 meters; at 50 Mbaud, the distance can reach 120 meters using 200-μm plastic-clad silica (PCS). The transmitter is a 3-pin device, and the receiver is a 4-pin device, both packaged in the Versatile Link housing. Versatile Link components can be interlocked (N-plexed together) to minimize space and provide dual connections using dual connectors. Various single and dual connectors, as well as POF cables, can be used with the Versatile Link components.
