HFBR-1525EZ Transmitter

HFBR-2525EZ Receiver

12 Megabaud Versatile Link Fiber Optic Transmitter

Data Sheet

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

 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

these components to prevent damage and/or degradation which may be induced by ESD.

Description

The HFBR-1525EZ transmitter is an LED in a low cost

plastic housing designed to efficiently couple power

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

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.

or can be easily field-terminated. A single transmitter

used with a single design.
