AFBR-2529SIZ

AFBR-2529SIZ is a DC-50MBd versatile link fiber-optic receiver with monitoring output. The receiver consists of an IC with an integrated photodiode providing a TTL logic family-compatible output. It is a 4-pin device, packed in a 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. It delivers inverted output signals, which means that LIGHT ON leads to Data out LOW and vice versa. Applications include industrial control and factory automation, extension of RS-232 and RS-485, high voltage isolation, elimination of ground loops, reducing voltage transient susceptibility, advanced maintenance management of optical links by monitoring the incoming optical receiver power.
