Description
The HFBR-1525EZ transmitter is an LED in a low cost
plastic housing designed to e ciently couple power
into 200 μm diameter Hard Clad Silica (HCS
) and 1 mm
diameter Plastic optical  ber (POF). The HFBR-2525EZ re-
ceiver incor porates a PIN detec tor and digital output IC
compat ible 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 recom mended 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  eld-terminated. A single transmitter
drive current for POF and HCS
allows both  bers to be
used with a single design.

HFBR-1525EZ Transmitter
The HFBR-1525EZ transmitter incorporates a 650 nm LED
in a light gray, nonconductive plastic housing. The high
light output power enables the use of both plastic optical
ber (POF) and Hard Clad Silica (HCS
)  ber. This transmit-
ter can be operated up to 12 MBd using a simple driver
circuit. The HFBR-1525EZ is com pat ible with all Versatile
Link connectors.

Notes:
1. Typical data are at 25°C.
2. Optical power measured at the end of 0.5 meters of 1 mm diameter plastic or 200 μm diameter hard clad silica  ber with a large area detector.
3. Minimum and maximum values for P
T
over temperature are based on a  xed drive current. The recommended drive circuit has temperature
compensation which reduces the variation in P
T
over temperature; refer to Figures 4 and 6.
4. Typical value measured from junction to PC board solder joint for horizontal mount package, HFBR-1525EZ.
5. Pins 5 and 8 are for mounting and retaining purposes, but are electrically connected; pins 3 and 4 are electrically isolated. It is recommended
that pins 3, 4, 5 and 8 all be connected to ground to reduce coupling of electrical noise.
6. Refer to the “Plastic Optical Fiber and HCS Fiber Cable and Connectors for Versatile Link” Technical Data Sheet for cable connector options for 1
