Data Sheet
Description
Features
SERCOS
Meets industrial SERCOS, PROFIBUS, and INTERBUS-S
standard
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 fiberoptic rings, with voltage isolation and noise immunity.
The HFBR-1505AZ and HFBR-2505AZ 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 Avago regarding
the plan for the 16 MBd device.)
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 recommended optical port of
the PROFIBUS optical fiber version but other connectors
are allowed as well. The HFBR-1515BZ and HFBR-2515BZ
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 Avago
regarding the plan for the 12 MBd device.)
SMA and ST® ports
650 nm wavelength technology
Specified for use with 1 mm plastic optical fiber and
200 μm hard clad silica
Auto-insertable and wave solderable
DC – 10 MBd data rate
RoHS-compliant
Applications
Industrial control data links
Factory automation data links
Voltage isolation applications
PLCs
Motor drives
Sensor, meter and actuator interfaces
INTERBUS-S
INTERBUS-S, a special open Sensor/Actuator Bus, is
finding a broad acceptance in the factory automation
industry. The HFBR-1505CZ and HFBR-2505CZ 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.
ST® is a registered trademark of AT&T.
HCS® is a registered trademark of OFS Corporation.
Package Information
All HFBR-X5X5XZ 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-insertion and wave soldering so it
is ideal for high volume production applications.
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, Avago
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.

NORMALIZED SPECTRAL OUTPUT POWER
Notes:
1. Typical data at 25˚C.
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.
7. 1.6 mm below seating plane.
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.
12. Moisture sensitivity level (MSL) is 3.

The HFBR-25x5AZ/BZ 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-2505AZ is compatible with SMA connectors,
while the HFBR-2515BZ mates with ST® connectors.
