Description
50 Megabaud Versatile Link Fiber Optic Transmitter And Receiver For 1mm Pof
Manufacturer
Avago Technologies
Datasheet
AFBR-T524Z/AFBR-R524Z
50 Megabaud Versatile Link Fiber Optic Transmitter
and Receiver for 1mm POF
Data Sheet
Description
The AFBR-T524Z transmitter utilizes a 650nm LED source
with integrated optics and driver IC for efficient coupling
into 1mm Polymer Optical Fiber (POF). The AFBR-R524Z
receiver incorporates a PIN detector and digital output IC.
The transmitter input and receiver output are compatible
with TTL logic families. The pair operates up to 50MBd at
distances up to 50 meters with 1mm POF using bi-phase
encoding scheme.
The transmitter is a 3-pin and the receiver is a 4-pin device,
packed in Versatile Link housing. Versatile Link compo-
nents 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 compo-
nents. Please contact Avago Technologies for details or
visit our company website at www.avagotech.com.
