SERCOS
SERCOS, an acronym for SErial
Realtime COmmunications
System, is a standard digital
interface for communication in
industrial CNC applications.
SERCOS is a European
(EN 61491) and international
standard (IEC 61491). The
optical interface allows data rates
of 2, 4, 8, and 16 MBd and data
transfer between numerical
controls and drives via fiber-optic
rings, with voltage isolation and
noise immunity. The HFBR1505A and HFBR-2505A
products comply with SERCOS
specifications for optical
characteristics and connector
style, and have guaranteed
performance up to 10 MBd.
(Typically the 16 MBd required
by SERCOS is possible as well
but please contact Agilent
regarding the plan for the
16 MBd device.)
ST® is a registered trademark of AT&T.
HCS® is a registered trademark of
SpecTran Corporation.
PROFIBUS
PROFIBUS, an acronym of
PROcess FIeld BUS, is an open
fieldbus standard defined for data
rates ranging from 9.6 kBd to
12 MBd in selectable steps for
wire and optical fiber. PROFIBUS
is a German national DIN 19245
standard and a European
CENELEC standard EN 50170.
The ST ® connector is the

PROFIBUS optical fiber version
but other connectors are allowed
as well. The HFBR-1515B and
HFBR-2515B comply fully to the
technical guideline using Plastic
Optical Fiber up to 6 MBd, and
have a guaranteed performance at
data rates up to 10 MBd.
(Typically the 12 MBd is possible
as well, but please contact Agilent
regarding the plan for the 12 MBd
device.)
INTERBUS-S
INTERBUS-S, a special open
Sensor/Actuator Bus, is finding a
broad acceptance in the factory
automation industry. The HFBR1505C and HFBR-2505C were
specially designed for this
application and can be used with
1 mm POF and 200 µm HCS fiber
at the specified data rates of
500 kBd and 2 MBd. The optical
transmission guideline is a
supplement of the German
National DIN E 19258 standard
draft. On the European level,

prEN 50254 is the draft of the
INTERBUS-S fieldbus.
insertion and wave soldering so it
is ideal for high volume
production applications.
Package Information
All HFBR-X5X5X series
transmitters and receivers are
housed in a low-cost, dual-in-line
package that is made of high
strength, heat resistant,
chemically resistant and UL 94
V-O (UL file # E121562) flame
retardant plastic. The
transmitters are easily identified
by the light grey colored
connector port. The receivers are
easily identified by the dark grey
colored connector port. The
package is designed for auto-
Handling and Design
Information
When soldering, it is advisable to
leave the protective cap on the
unit to keep the optics clean.
Good system performance
requires clean port optics and
cable ferrules to avoid
obstructing the optical path.
Clean compressed air often is
sufficient to remove particles of
dirt; methanol on a cotton swab
also works well.
Recommended Chemicals for
Cleaning/Degreasing X5X5X
Products
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane.
Other: soap solution, naphtha.
Do not use partially halogenated
hydrocarbons such as
1,1,1 trichloroethane, ketones
such as MEK, acetone,
chloroform, ethyl acetate,
methylene dichloride, phenol,
methylene chloride or
N-methylpyrolldone. Also, Agilent
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.
CAUTION: The small junction size inherent in the design of these components increases the
components’ susceptibility to damage from electrostatic discharge (ESD). 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.

2. Optical power measured at the end of 0.5 meters of 1 mm diameter plastic optical 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 PT over temperature, refer to Figures 4 and 6.
4. Thermal resistance is measured with the transmitter coupled to a connector assembly and fiber, and mounted on a printed circuit
board.
5. To further reduce the thermal resistance, the cathode trace should be made as large as is consistent with good RF circuit design.
6. For IF,PK > 60 mA, the duty factor must maintain IF,AVG ≤ 60 mA and pulse width ≤ 1 µs.

8. Minimum peak output power at 25˚C is –5.3 dBm (POF) and –16.0 dBm (HCS®) for 1505C series only.
9. Optical power measured at the end of 1 meter of 1 mm diameter plastic or 200 µm hard clad silica optical fiber with a large area
detector.
10. Pins 1 and 4 are for mounting and retaining purposes, but are electrically connected; pins 5 and 6 are electrically isolated. It is
recommended that pins 1, 4, 5, and 6 all be connected to ground to reduce coupling of electrical noise.
11. Output power with 200 µm hard clad silica optical fiber assumes a typical –10.5 dB difference compared to 1 mm plastic optical
fiber.

HFBR-25x5A/B Receivers
The HFBR-25x5A/B receiver
consists of a silicon PIN
photodiode and digitizing IC to
produce a logic compatible
output. The IC includes a unique
circuit to correct the pulse width
distortion of the first bit after a
long idle period. This enables
operation from DC to 10 MBd
with low PWD for arbitrary data
patterns. The receiver output is a
“push–pull” stage compatible with
TTL and CMOS logic. The
receiver housing is a dark grey,
conductive plastic. The
HFBR-2505A is compatible with
SMA connectors, while the
HFBR-2515B mates with ST®
connectors.
