Data Sheet
Description
The HFBR-1525EZ transmitter is an LED in a low cost
plastic housing designed to efficiently couple power
into 200 μm diameter Hard Clad Silica (HCS^) and 1 mm
diameter Plastic optical fiber (POF). The HFBR-2525EZ re-
ceiver incorporates a PIN detector and digital output IC
compatible with CMOS and TTL logic families.
HFBR-1525EZ/HFBR-2525EZ links operate from DC to 12
MBd at distances up to 50 meters with 1 mm POF and up
to 500 meters with 200 μm HCS^. No minimum link dis-
tances are required when using recommended circuits,
simplifying design.
Versatile Link components can be interlocked (N-plexed
together) to minimize space and to provide dual connec-
tions with the duplex connectors. Up to eight packages
can be interlocked and inserted into a printed circuit
board.
POF and HCS^ are available in pre-connectored lengths
or can be easily field-terminated. A single transmitter
drive current for POF and HCS^ allows both fibers to be
used with a single design.
Features
 RoHS-compliant
 Data transmission at signal rates of dc to 12 MBd
 Up to 50 meters distances with 1 mm Plastic Optical
Fiber (POF)
 Up to 500 meters distances with 200 μm Hard Clad
Silica (HCS^)
 Wide dynamic range receiver allows operation from
zero to maximum link distance with a single transmit-
ter drive current
 Link distances specified for variations in temperature,
power supply, and fiber attenuation
 DC coupled receiver with CMOS/TTL output for easy
designs: No data encoding or digitizing circuitry re-
quired
 Pulse width distortion (PWD) controlled to limit dis-
tortion from low duty cycle or burst mode data
 High noise immunity
 Compatible with Avago’s versatile link family of con-
nectors, for easy termination of fiber
Applications
 Industrial control and factory automation
 Serial field buses
 Intra-system links; board-to-board, rack-to-rack
 Extension of RS-232, RS-485
 Elimination of ground loops
 High voltage isolation
 Reduces voltage transient susceptibility
