HFBR-150xAFZ / 2555AFZ (SMA Tx/Rx for SERCOS)
Full Metal Fiber Optic Transmitter and Receiver
for SERCOS Applications
Data Sheet
Description
SERCOS
Features
•ꢀ Meets industrial SERCOS standard
•ꢀ SMA ports
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 HFBR-150xAFZ and HFBR-2555AFZ products comply
with SERCOS specifications for optical characteristics and
connector style, and have guaranteed performance at 4, 8,
and 16 MBd data rates.
•ꢀ 650 nm wavelength technology
•ꢀ Metal housing and port
•ꢀ Specified for use with 1 mm plastic optical fiber and
200 µm hard clad silica
•ꢀ Auto-insertable and wave solderable
•ꢀ Supports SERCOS 4, 8 and 16 MBd
•ꢀ RoHS-compliant
Applications
•ꢀ Industrial control data links
•ꢀ Factory automation data links
•ꢀ Voltage isolation applications
•ꢀ PLCs
•ꢀ Motor drives
•ꢀ Sensor, meter and actuator interfaces

Package Information
Recommended Chemicals for Cleaning/Degreasing
HFBR-150xAFZ and HFBR-2555AFZ Products
The HFBR-150xAFZ transmitters and HFBR-2555AFZ re-
ceiver are housed in a dual-in-line metal package that is
high strength. The package is designed for auto-insertion
and wave soldering so it is ideal for high volume produc-
tion applications.
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 halo-
genated hydrocarbons because of their potential environ-
mental harm.
Handling and Design Information
When soldering, it is advisable to leave the protective cap
on the unit to keep the optics clean. Good system per-
formance 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.

2. POF HFBR-ExxyyyZ 0.23 dB/m worst case attentuation.
3. HCS Worst Case Attenuation is 10 dB/km (0° C to 70° C) and 12 dB/km (-40° C to 85° C).
4. Including a 3 dB optical safety margin accounting for link service lifetime.
5. Including a 2 dB optical safety margin accounting for link service lifetime.
6. Signaling rate up to 10 MBd.
7. Signaling rate up to 16 MBd.
8. For PWD calculation, the pulsewidth of the receicer output is compared versus the pulsewidth of the electrical input signal of the transmitter. PWD
= PW_RXout - PW_TXin. Note, that the HFBR-2555AZ is an inverting receiver, thus an electrical high pulse at the transmitter input (LED on) causes
an electrical low at the receiver output. For the characterization, the transmitter has been driven with an ideal (duty cycle = 50%) PRBS7 pattern
input signal.

Notes:
1. Typical data at 25° C.
2. Optical power measured at the end of 0.5 meters of 1 mm diameter plastic or 200 µm hard/plastic clad silica optical fiber with a large area
detector.
3. Minimum and maximum values for PT over temperature are based on a fixed drive current.
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. Output power with 200 µm hard clad silica optical fiber assumes a typical -10.5 dB difference compared to 1 mm plastic optical fiber.
9. 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.
10. Thresholds for rise time and fall time are 10% and 90%.
EYE SAFETY: The HFBR-150xAFZ is a Class 1 LED Product and eye safe when used within the data sheet limits and
under normal operating conditions. This includes all reasonably foreseeable single fault conditions per IEC60825-1
and amendments.
