DC to 5MBd Versatile Link Fiber Optic Receiver for 1mm POF

Currently Viewing:

The Avago AFBR-2521CZ is a DC-5MBd Versatile Link POF receiver device designed to operate with any type of signal from DC up to 5 MBd at link distances up to 50 meters using 1mm 0.5NA POF or 500 meters using 220µm 0.37NA PCS. The receiver device consists of an IC with an integrated photodiode to produce a logic compatible output. The output is compatible with TTL logic families.
The AFBR-2521CZ is a 4-pin device packed in a Versatile Link housing. Versatile Link components can be interlocked (N-plexed together) to minimize space and provide dual connections with the duplex connectors. Various simplex and duplex connectors as well as POF cables are available for Versatile Link components
