Introduction
CFP2 Evaluation Kit Features
This printed circuit board and evaluation kit provides the
designer with a convenient way to evaluate the electrical and optical performance of the Avago Technologies’
Ten-Channel CFP2 100GBASE-SR10 transceiver. This user
guide offers a description of the evaluation board and basic operating instructions.
• 20 side-mounted SMA connectors to connect to all 10
differential TX high-speed lanes
The AFBR-8420EVB evaluation board is to be used in conjunction with Avago Technologies’ AFBR-8420Z CFP2 SR10
module. The AFBR-8420Z is a ten-channel pluggable, parallel, fiber optic transceiver for 100 Gbps Ethernet applications.
The transceiver supports high-speed serial links over
multi-mode fiber at signaling rates up to 103.125 Gb/s (a
serial line rate of 10.3125 Gb/s per channel) for link distances up to 100 m with OM3 fiber and 150 m with OM4
fiber. The product is compliant with the CFP2 industry
agreement for mechanical and low-speed electrical specifications. High speed electrical and optical specifications
are compliant with IEEE 802.3ba Clause 86 for 100GBaseSR10 media, Clause 86A for CPPI electrical interface.

CFP2 Evaluation Board Configuration
CFP2 Evaluation Board Power Jumper Configuration
On the CFP2 Power Input section there are 3 sets of power supply inputs:
• Vcc33 and GND
• Vcc33_Eval and GND
• Vcc33_Sense and GND_Sense
1. To run both the evaluation board and the CFP2 module off of a single 3.3 V supply, configure the power jumper on
the CFP2 evaluation board as follows:
Figure 3. Evaluation Board Jumper Configuration, single supply
The configuration buses the Vcc33_Eval evaluation board rail and the Vcc33 module rail together.
2. To run the evaluation board and CFP2 module off of two different 3.3V supplies, remove the jumpers.
The recommended operating power supply voltage spec at the input of the CFP2 module, per the datasheet, is 3.135V to 3.465V.
Use the Vcc33_Sense line to ensure the module receives this voltage.
With CDRs ON the absolute maximum power consumption is 9 W. So at maximum power and lowest voltage the current through the wire
can be: 9W/3.135V = 2.9 A. The user must ensure that the power supply is not current limited. In addition, there will be an IR drop through
the power cables @ ~2.9 A; use the Sense line to compensate for this drop. It is recommended that the Power Supply implements settings
for max Voltage (say 4V) and max Current draw (say 3.5A) to prevent any over-voltage or over-current situation when using the sense lines.
CFP2 Evaluation Board DIP Switch CFP2 Evaluation Board
Configure the DIP switch on the CFP2 evaluation board as follows (board should have this default configuration):

Avago Technologies USB-to-MDIO Controller
USB-to-MDIO Controller Configuration
1. Connect the ribbon cable and the USB cable to the MDIO controller, as shown in Figure 6.
2. Connect the ribbon cable to the CFP2 evaluation board, as shown in Figure 7.
3. Connect the USB end of the cable to the laptop or computer running Windows 7 or Windows XP. See section ‘USB-to
-MDIO Controller Driver Installation’.

USB-to-MDIO Controller Driver Installation
Included with the Avago Evaluation Kit is a CD that contains the driver for the USB to MDIO Controller (Also known as ‘A
port’). Place the CD into the CD/DVD drive of the desktop PC or laptop and find the file "Aport.msi".
Note:
The installation of CFP2 User GUI should install the driver for MDIO
host as well. This section should be used only if the user experiences
any issues or if the user does not intend to install the CFP2 User GUI.
1. Run the Aport.msi program
2. Follow the installation Wizard Instructions
Figure 8. Run CMD.exe as administrator
3. Plug-in the MDIO controller. Navigate to Device Manager and confirm that Windows shows the device under Device
Manager → Ports (COM & LPT) → A port.
Figure 9. Device Manager - Verify ‘A port’ has been installed

CFP2 Test Setup
CAUTION! Always use proper ESD protection! At a minimum, use a properly grounded ESD wrist strap when handling the parts and boards.
1. Ensure the evaluation kit comes with all piece parts
2. Ensure the evaluation board jumpers and DIP switches are correct.
3. Connect the Avago Technologies USB-to-MDIO controller to the laptop or computer using the USB cable.
4. Connect ribbon fiber from the Avago Technologies USB-to-MDIO controller to CFP2 board.
5. Connect 3.3V DC power to the CFP2 evaluation board.
Figure 10. 3.3 V Power Supplies – power cables
6. Insert an Avago Technologies’ AFBR-8420Z CFP2 SR10 module into the connector/cage.
Figure 11. Insertion of the CFP2 Module and Insertion of MTP 24 fiber optic cable (2x12)
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.

(Channels 0 through 9). The signal can originate from a BERT or ASIC/FPGA board.
b. To measure optical output parameters, use a 24 fiber (2x12) break-out cable with MTP-to-SC/FC Connectors. See
Figure 12, black arrow.
c. To establish a full link,
i. Connected a 24 fiber MTP/MPO connector to another CFP2 Evaluation Board and CFP2 transceiver to establish a full duplex
link (Figure 12). The CFP2 optical link can be up to 100 m OM3 or 150 m OM4 multi-mode fiber.
ii. Or use the 24 fiber (2x12) break-out cable to loop back the signal to the DUT PIN receiver.
iii. Or use a loop back cable to route the signal to the DUT PIN receiver
d. Receiver electrical output signals exit via top mounted SMA connectors Channels 0 through 9. These are high
speed differential output signals.
e. Measure Optical Receiver output parameters using SMA cables to an electrical Digital Communications Analyzer.
f. Measure Bit Error Rate by completing the link back to the BERT or ASIC/FPGA board.
g. Receiver Sensitivity Measurement can be made with a similar configuration; the optical input power to the CFP2
optical Rx can be varied using an Optical Attenuator (850 nm).

in HEX” and “Visible ASCII Only”.
Figure 23. ASCII View option
5. Clicking “Edit Enabled” button allows the user to make direct changes to the contents of the Volatile Fields. Once
Edits are enabled, the user can click in the individual cells and directly change volatile bytes or bits. Edited cells will
be highlighted in yellow.
• For the change to be written into the CFP2 module, the user must click “Write Updated Register”, which will write
all changes on the VR page to the module.
