QSFP/QSFP+ Transceiver and

Active Optical Cable Evaluation Kit

User Guide

Introduction

This Evaluation kit provides the designer with a conve-

nient way to evaluate Avago Technologies QSFP/QSFP+

Transceivers and/or Active optical cables (AOCs). The de-

signer can evaluate the management Interface, as well as

the electrical and optical performance. This user guide of-

fers a brief description of the evaluation board, the Graph-

ical User Interface along with basic operating instructions.

The Avago technologies QSFP/QSFP+ devices consist of

Four - Channel, Pluggable, Parallel-Fiber-Optics Transceiv-

ers and Active optical cables. These are high performance

ber optics modules and cables for short-range parallel

multi-lane data communication and interconnect appli-

cations. The transceivers and active optical cables inte-

grate four data lanes in each direction with up to 40 Gbps

aggregate bandwidth. Each lane can operate up to 10

Gbps and up to 100 m at 10Gbps using OM3 ber. These

modules and active cables are designed to operate over

multimode ber systems using a nominal wavelength of

850nm. The electrical interface uses a 38-contact edge

type connector. The optical interface uses an 8 or 12 ber

MTP® (MPO) connector. These modules and active cables

incorporate Avago Technologies proven integrated circuit

and VCSEL technology to provide reliable long life, high

performance, and consistent service.

Electrical Connections

Electrical connections from the modules/AOCs to the

evaluation board are achieved through a 38 contact edge

type connector. This connector enables the user to easily

interchange modules/AOCs allowing testing of many de-

vices using a single evaluation board.

These evaluation boards provide access to all transmit and

receive high-speed I/O’s through straight PCB mount SMA

connectors. AC coupling capacitors are located inside the

QSFP/QSFP+ transceiver of active optical cable and are

not required on the host board.

Descriptions of the test access points including the high-

speed I/O connections and control and sense outputs are

listed in Table 1.

High Speed Input/Output Lines

There are 4 dierential pairs of high-speed lines on the

evaluation board. The Transmitter has 4 dierential pairs

of input lines, TX[1:4]p/n and the Receiver has 4 corre-

sponding pairs of dierential output lines, RX[1:4]p/n. All

high-speed dierential data lines are 100 W dierential

controlled impedance transmission lines of equal length

to minimize inter-channel skew. It is recommended that

all high-speed data lines be terminated with 100 W dier-

entially when not in use to eliminate back-reection noise.

Control Signal Pins

TWS interface

TWS interface is implemented in the modules/AOCs as

slave devices and compatible with industry standard two-

wire serial protocols compatible to Atmel Two-wire Serial

EEPROMs such as AT24C01A.

Figure 3. Test Conguration

Fiber Ribbon Cable and Connectors

Avago Technologies recommends the use of 50/125um

multimode 12-ber ribbon ber cable with MTP® connec-

tors to implement tests of the QSFP/QSFP+ Transceivers.

Note, OM3 ber should be used for link lengths above

35m. Important: This cable should not have a twist; the TX

channels must go to the corresponding RX channels on

the other end. This maintains the correct channel polarity

with respect to the transmit/receive pair (e.g. Tx channel

0 connects to Rx channel 0, Tx channel 4 connects to Rx

channel 4). Fiber breakout cable with MTP®-to-SC con-

nectors is useful when testing individual channel perfor-

mance. For recommended cable, see reference [4] and for

Optical receptacle and Channel Orientation see reference

[5].

Power Supply

The each board requires 3.3V dc power supplies connec-

tion at connector J17 and J18 labeled as “3.3VDC” or 9V

DC at connector J20 from the wall plug power source. For

example, the Transceiver module AFBR-79Q4Z will draw

up to 425mA current through 3.3VDC when all channels

are enabled and transmitting and receiving data under

nominal operating conditions

Power Supply Noise Filter

This follows the Recommended Host board Power Sup-

ply Filtering as shown in the INF-8436i QSFP Transceiver

Specication Revision 1.0 or SFF-8436 Specication for

QSFP+ Optical Modules or the QSFP AFBR-79Q4Z Trans-

ceiver Datasheet Figure 6.

Electro-Optical Test Congurations

A commonly used test conguration for evaluating par-

allel optical components is shown in Figure 3. It is often

dicult to generate 4 separate channels of data patterns

in a test environment and often dicult to measure and

conduct simultaneous bit error rate analysis on all 4 chan-

nels. Four channel parallel BERTs may used. As well, single

channel BERT (Agilent 71603B) will provide adequate sin-

gle channel data.

Using the test conguration shown in Figure 3, transmit-

ter optical characteristics including jitter, rise/fall time,

output power, and eye diagrams can be measured. Re-

ceiver characteristics including electrical jitter, rise/fall

time, sensitivity, and eye diagrams can also be measured.

Avago Evaluation Kit and QSFP Software User Guide

The Avago QSFP/QSFP+ 4-channel Parallel Optics Trans-

ceivers and Active Optical cables provide the design en-

gineer with features that can provide signicant exibility

in their system design. The module/AOC provides the

user the ability to remotely monitor the health of the link

through a comprehensive set of digital diagnostics. Note,

however, that in order to take advantage of fully calibrat-

ed digital diagnostics, the user must have purchased de-

vices with DMI enabled i.e. “-D” part number

This appendix includes basic user information for the Ava-

go Technologies QSFP/QSFP+ evaluation kit as well as an

instruction guide for the accompanying software graphic

user interface (GUI).

Installing the Avago POD Viewer Software:

Included with the Avago Evaluation Kit is a CD that con-

tains the self-install customer user interface software. This

user interface software is PC and Windows compatible.

Place the CD into the CD/DVD drive of your desktop PC or

laptop. The software should begin to install automatically.

If this does not happen open My Computer and double-

click the CD-ROM drive.

Follow the instructions as prompted by the installer.

Once installed, an icon entitled “Avago’s QSFP Viewer” will

appear on your desktop along with an Avago ReadMe text

le which includes detailed reference information about

the GUI installation and revision.

Before starting the GUI software it is recommended that

you connect and power up the QSFP/QSFP+ Evaluation

Board and I-Port cables.

Connecting the Avago QSFP/QSFP+ Evaluation Board

Included in the Avago Evaluation Kit is an Avago QSFP/

QSFP+ Evaluation PCB. Optionally included is an I-Port

device and associated cables. If you did not order an I-

Port device as part of the evaluation kit, please use a com-

patible I-Port device.

Figure 5. Setting the Device Address

Figure 4. Evaluation Board Connections

The i-Port device typically also comes with its own soft-

ware and can be loaded to the PC. Once complete, con-

nect the i-Port device and Vcc as indicated in the gure

above.

Set the four DIP switches as indicated below:

Avago POD Viewer Software

The evaluation software can be accessed by double click-

ing the desktop icon “Avago’s QSFP Viewer”. Once the soft-

ware starts the Avago template will appear on the screen

while the PC searches the COM ports for an active device.

This may take a few seconds.

Avago QSFP Viewer Software

QSFP Tab

When the software starts it will initially default to the tab titled “QSFP”.

Registers Tab

The Registers Tab provides the user the ability to view, read and write to the user accessible registers in the Avago QSFP

device.

Figure 8. Register Tab, Base Page

Registers List Window:

You may need to resize the Registers window and collapse/

expand the branches to see the complete view of the pag-

es available. Note that there are three main branches in

the Register List eld: QSFP Base Page, QSFP Page 0 – SE-

RIAL ID INFORMATION, and QSFP Page 2 – USER AREA.

The left window titled “Register List” provides the address

and name of the register elds.

The register addresses are in decimal format, however,

when you click an address in the “Register List” window,

you will notice the corresponding register address in

Hexadecimal is highlighted in the “Field Display” window.

You may expand the elds in a tree format in the “Register

List” that are in RED letters. This allows the user to view the

eld denitions down to the single bit level. Fields that

cannot be expanded are only dened at the byte level.

The user denable/writable elds can be found by looking

at the “Decoded Data” window. If a check box exists next

to a bit or byte eld, that eld is writable. The writable

bits/bytes correspond to the INF-8436i QSFP Transceiver

Specication Revision 1.0 and SFF-8436 Specication for

QSFP+ Optical Modules

Figure 9. Register List and Decoded Data Window

Decoded Data Window:

Directly to the right of the “Register List” window there is a

window titled “Decoded Data”. It is here that you can view

the last read values corresponding to the register in “Reg-

ister List”. It is recommended that when you rst open

the QSFP Module Evaluation Program you press the “Read

ALL” button to see the current state of all elds. Values will

be in Hexadecimal or will be in text describing the state of

a bit eld. Note the hexadecimal value of a byte eld can

also be viewed in “Field Display”

If you expand the “Register list” to reveal the bit elds, you

will see a corresponding tree format in the “Decoded Data”

tab. It is in this expanded “Decoded Data” tab that you can

make changes to the user denable/changeable bits. Only

elds that are highlighted yellow and have a check mark

box next to them are writable/changeable bit elds.

You can change the bit or byte value by changing the val-

ue in the desired eld AND clicking on the check box such

that a check mark appears in the box.

When the Write Checked or Write Current button is

pressed, these values will be written to the device.

Note: There is an alternate way to write to user writable

elds. If you click the “Edit” option instead of the “Field

Display” option at the bottom, you can change bit elds

in the “Field Display” window directly and then click Write

Checked or Write Current button. However, be aware that

un-writable bits will still not be aected.

Write Checked, Write Current, Read ALL, Read Page and Read Register

If the read operation fails after repeated tries, close the

Avago QSFP Viewer software, review all board connec-

tions, power cycle the evaluation board, and restart the

Avago QSFP Viewer. If problem persists, please contact

your local Avago eld representative.

One useful feature of the Avago QSFP Viewer software is

the Register Reports Tab. This tab allows the user to select

sections of the register content of a given device, custom-

ize the format, and then save the le to a text le or print

automatically to a networked printer.

This feature can be used for documenting or logging de-

vice conditions, register dumps, verifying performance

during transient operating conditions, and simplifying

reporting necessary during product evaluation and test.

Unless otherwise specied the reports or text les will be

saved in the default folder for Register Reports. This is in

the Reports folder in the Avago Viewer Program folder.

Default location:

C:\Program Files\Avago\QSFP Viewer\Reports\

Figure 10. Register Reports

In order to write new user-dened bit/byte values to the

device (after the user has clicked at least ONE checkmark

box), the user must click the Write Checked or Write Cur-

rent button on the bottom left. The “Write Checked” but-

ton will write all changes that were made in the Decoded

Data bit elds using the check boxes. The “Write Cur-

rent” button will only update the register eld currently

When the Avago Evaluation Board hardware is correctly

connected and powered the user can read from the de-

vice under test by clicking the “Read All” button in the low-

er left part of the Registers Tab. It is recommended that

when you rst open the QSFP Module Evaluation Program

you press the “Read ALL” button to see the current state of

all elds.

In order to read back the data in the registers you must

hit the “Read All”, “Read Page” or “Read Register” button.

“Read All” will do a read for all QSFP pages - QSFP Base

Page 0 – SERIAL ID INFORMATION Page 1 and USER AREA

Page 2. The “Read Page” button will only update the page

you are currently on. “Read Register” will only read and

update the register eld the user has clicked.

TX/RX DMI Tab

In order to take advantage of fully calibrated digital diag-

nostics, the user must have purchased devices with DMI

enabled i.e. “-D” part number

The Avago QSFP 4-channel parallel optic transceiver and

active optical cable have a number of useful real-time di-

agnostic indicators. Using the TX/RX DMI tab, the user can

view all critical operating conditions of the module/AOC-

end at once. This view shows basic device identication

information, real-time operating condition diagnostics,

and control status indicators.

Basic Device ID Information

Part Number, Vendor, Serial Number, and Date Code

Operating Condition Diagnostics

Case Temperature, Vcc33, Transmitter Laser Bias

Current, Transmitter optical power, Received Optical

Power (mW and dBm)

Channel by channel RX LOS and Hi/Low Power

Alarm Status

This page also includes access to some basic control reg-

isters so that the user can easily verify operation. By click-

ing the check-boxes under Soft Control Options you can

toggle the status of Rx Disable, RX Squelch Enable, RX LOS

MASK on/o, Tx Disable, Tx Squelch Enable, and TX LOS

Mask ON.

This tab allows for one time reading of these registers by

clicking the READ ONCE button in the lower right. Alter-

natively, you can continuously poll these registers over

time by clicking the START SCAN button in the lower right.

This is a useful feature for over temperature debug and

verication.
