Broadcom's AFBR-2529SIZ receiver consists of an IC with an integrated photodiode providing a TTL logic family compatible output. The receiver operates any type of signal from DC up to 50 MBd at distances up to 50 m with 1 mm polymer optical fiber (POF) up to 200 m at 10 MBd and 120 m at 50 MBd with 200 μm plastic-clad silica (PCS), respectively. It 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. The AFBR-2529SIZ features a monitor output providing an analog voltage proportional to the average optical input power. Various simplex and duplex connectors, as well as POF cables, are available for Versatile Link components. For optical links with AFBR-2529SIZ, Broadcom’s AFBR-16xxZ transmitters use a 650 nm LED source with integrated optics and driver IC recommended. The AFBR-2529SIZ delivers inverted output signals, which means that light ON leads to data out LOW and vice versa.
