Small Form Pluggable (SFP) Transceivers
Product Brief
Features
• Included in the HFBR-0534 Evaluation Kit:
- An evaluation board
- Software
- 9 pin serial cable
- 110 V/220 V power supply
• On board potentiometer to adjust the voltage to the
SFP for 2.64 to 3.65 V
• Test points for easy probing of Mod_Def signals, TX_
Fault and LOS signals.
• On-board hardware switch for toggling of TX_Disable
control signal
• Onboard LEDS to monitor the status of :
- LOS LED - turns on when LOS hard-signal is asserted
by SFP module
- Mod_Def(0) LED – turns on when a module is pres-
ent
- TX_Fault LED – turns on when TX_Fault is asserted
by module
- TX_disable LED – on when TX is enabled, turns o
when TX is disabled
• GUI software allows easy decoding of 0xA0 and 0xA2
page byte contents (per SFF-8472 MSA)
• GUI sub-window enables quick execution of byte write
operations; delay between write operations is adjust-
able

• Printable Reports of SFP content and decoded infor-
mation
• Reading and writing to on-board SFP memory
• Optical / Electrical testing of all Avago SFP modules
Description
For bench top evaluation, the HFBR-0534 is the
recommended tool for Avago Technologies new Small-
Form-Pluggable (SFP) transceivers with the Diagnostic
Monitoring Interface (DMI). The HFBR-0534 includes
the necessary two-wire serial interface to communicate
with the Diagnostic Monitoring Interface and provides a
standard 9 pin serial interface to connect to a PC.
A Window’s based Graphical User Interface (GUI) provides
the user an easy, straightforward way to communicate to
SFP transceivers. The interface software is customized
to allow quick verication of the feature sets dened in
the SFF-8472 MSA. The HFBR-0534 requires only one
input DC supply voltage (9 V to 12 V) to power all board
components, including the micro-controller, and both the
receiver and transmitter sections of the SFP transceiver.
Just plug in the DMI SFP and your ready to go. Using
Avago Technologies custom PC software (included as partcustom PC software (included as part
HFBR-0534 evaluation board kit), the user can then read
specic bytes from the SFP’s memory pages (decoding into
ASCII or HEX), access and log the internal measurements of
the transceiver (temperature, supply voltage, transmitter
bias current, transmitter output power, and received
optical power) as well as program the device EEPROM.
Using a Bit-Error-Ratio Tester (BERT) and a Digital
Communication Analyzer (DCA), the HFBR-0534 is also
suitable for evaluating the optical characteristics, including
the eye diagram, jitter, and rise/fall time and the electrical
characteristics, including the receiver electrical eye
diagram, jitter, and rise/fall time.
