10 Megabaud Versatile Link Fiber Optic
Transmitter and Receiver
for 1 mm POF and 200 µm HCS

Data Sheet
Description
The HFBR-0508 Series consists of a fiber-optic trans-
mitter and receiver operating at a 650 nm wave-
length (red). The HFBR-1528 transmitter is an
LED in a low cost plastic housing designed to ef-
ficiently couple power into 200 µm diameter HCS
and 1 mm diameter POF. The HFBR-2528 receiver incor-
porates a PIN detector and digital output IC compatible
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 to 500 meters
with 200 µm HCS
®
. No minimum link distances are re-
quired when using recommended 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.
