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
and connector style (SMA).

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.

6. When changing µW to dBm, the optical
power is referenced to 1 mW (1000
µW). Optical Power P(dBm) = 10 log
[P (µW)/1000 µW].
7. Measured at the end of 1mm plastic
fiber optic cable with a large area
detector.
8. 8 mA load (5 x 1.6 mA), RL = 560 Ω.
9. Propagation delay through the system
is the result of several sequentially
occurring phenomena. Consequently it
is a combination of data-rate-limiting
effects and of transmission-time
effects. Because of this, the data-rate
limit of the system must be described
in terms of time differentials between
delays imposed on falling and rising
edges. As the cable length is increased,
the propagation delays increase. Data-
rate, as limited by pulse width distor-
tion, is not affected by increasing cable
length if the optical power level at the
receiver is maintained.
1. 2.0 mm from where leads enter case.
2. Typical data at TA = +25°C.
3. Thermal resistance is measured with
the transmitter coupled to a connector
assembly and fiber, and mounted on a
printed circuit board.
4. Pins 2, 6, and 7 are welded to the
cathode header connection to minimize
the thermal resistance from junction to
ambient. To further reduce the thermal
resistance, the cathode trace should be
made as large as is consistent with
good RF circuit design.
10. Pulse width distortion is the difference
between the delay of the rising and
falling edges.
11. Both HFBR-1602 and HFBR-1604
meet the SERCOS "low attenuation"
specifications when operated at 35 mA;
only HFBR-1604 meets the SERCOS
"high attenuation" limits when operated
at 60 mA.
5. PT is measured with a large area
detector at the end of 0.5 metre of
plastic optical fiber with 1 mm
