Description
The HFBR-0508 Series consists of
a fiber-optic transmitter and
receiver operating at a 650 nm
wavelength (red). The HFBR1528 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 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
required 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 preconnectored 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.
HCS ® is a registered trademark of SpecTran Corporation.
CAUTION:. It is advised that normal static precautions be taken in handling and assembly of these components
to prevent damage and/or degradation which may be induced by ESD.
