interface specification was written
by a joint working group of the
VDW (German Machine Tool
Builders Association) and ZVEI
(German Electrical and Electronic
Manufacturer’s Association) to
allow data exchange between NC
controls and drives via fiber optic
rings, with isolation and noise
immunity. The HFBR-0600 family
of fiber optic transmitters and
receivers comply to the SERCOS
specifications for transmitter and
receiver optical characteristics

Description
The HFBR-0600 components are
capable of operation at symbol
rates from DC to over 2 MBd and
distances from 0 to over 20
metres. The HFBR-1602 and
HFBR-1604 transmitters contain
a 655-nm AlGaAs emitter capable
of efficiently launching optical
power into 1000 µm plastic
optical fiber. The optical output is
specified at the end of 0.5 m of
plastic optical fiber.
collector Schottky output
transistor. The HFBR-2602 is
designed for direct interfacing to
popular logic families. The
absence of an internal pull-up
resistor allows the open-collector
output to be used with logic
families such as CMOS requiring
voltage excursions higherthan
V . The HFBR-2602 has a
dCyCnamic range of 15 dB.

CAUTION: The small junction sizes inherent to the design of this component increase the component's
susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be
taken in handling and assembly of this component to prevent damage and/or degradation which may be
induced by ESD.
