HFBR-2525EZ Receiver
12 Megabaud Versatile Link Fiber Optic Transmitter
and Receiver for 1 mm POF and 200 μm HCS®
Data Sheet
Description
The HFBR-1525EZ transmitter is an LED in a low cost
plastic housing designed to efficiently couple power
into 200 μm diameter Hard Clad Silica (HCS) and 1 mm
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
to 500 meters with 200 μm HCS. No minimum link dis-
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.
POF and HCSare available in pre-connectored lengths
or can be easily field-terminated. A single transmitter
drive current for POF and HCSallows both fibers 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
fiber (POF) and Hard Clad Silica (HCS) fiber. This transmit-
ter can be operated up to 12 MBd using a simple driver
circuit. The HFBR-1525EZ is compatible 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 fiber with a large area detector.
3. Minimum and maximum values for PT over temperature are based on a fixed drive current. The recommended drive circuit has temperature
compensation which reduces the variation in P over temperature; refer to Figures 4 and 6.
T
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
mm plastic and 200 μm HCS optical fiber.
