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

.

No minimum link distances are

required when using recom-

mended circuits, simplifying

design.

Versatile Link components can be

interlocked (N-plexed together) to

minimize space and to provide

dual connections 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.

Description

The HFBR-0508 Series consists of

a fiber-optic transmitter and

receiver operating at a 650 nm

wavelength (red). The HFBR-

1528 transmitter is an LED in a

low cost plastic housing designed

to efficiently couple power into

200

µm

diameter HCS and 1 mm

diameter POF. The HFBR-2528

receiver incorporates a PIN detec-

tor and digital output IC compat-

ible with CMOS and TTL logic

families.

HFBR-0508 links operate from

DC to 10 MBd at distances up to

50 meters with 1 mm POF and up
