AFBR-800EVK and AFBR-800EVB
MiniPOD Evaluation Kit and Evaluation Board
For MiniPOD Pluggable Parallel-Fiber-Optics Modules
User Guide
Introduction
The purpose of this evaluation kit an evaluation board is
to provide the designer with a convenient way to evaluate
the electrical and optical performance of the Avago
Technologies’ Twelve-Channel MiniPOD transmitter and
receiver modules. This user guide o ers a description
of the AFBR-800EVB evaluation board along with basic
operating instructions.
The AFBR-800EVB Evaluation Rev. 4 board is to be used in
conjunction with the Avago Technologies AFBR-81uVxyZ
and AFBR-82uVxyZ family of Tx and Rx MiniPOD modules.
The AFBR-81uVxyZ and AFBR-82uVxyZ are twelve-channel, pluggable, parallel, ber-optic MiniPOD transmitter
and receiver modules, respectively. These high performance modules are intended for short-range multi-lane
data communication and interconnect applications.
Twelve data lanes transport greater than 120 Gbps
aggregate bandwidth. Each lane can operate at 10.3125
Gbps up to 100 m using OM3 ber. These modules are
designed to operate over multimode ber systems using
a nominal wavelength of 850nm. The electrical interface
uses a 9x9 MEG-Array connector with 1.27 mm pitch and
4mm contact mate height. The optical interface uses
a 12- ber Prizm™ to MPO/MTP connector (included in
the kit). These modules incorporate Avago Technologies’ proven integrated circuit and VCSEL technology to
provide reliable long life, high performance, and consistent operation.
Features
The AFBR-800EVB Evaluation board can be used with
the
– Avago Technologies AFBR-81uVxyZ 12 channel
transmitter
– Avago Technologies AFBR-82uVxyZ 12 channel
receiver
Access to Low speed signals, for example, Int_L/Reset_L
24 Side mounted SMA connectors to connect to 12
di erential TX or RX high speed lanes

Basic Operating Instructions for MiniPOD module Device
Under test:
A. Insert the M iniPOD (DUT) onto the Meg-Array connector
on the Evaluation board labeled 1 in Figure 4
B. Apply 3.3V and 2.5V to power pins labeled 2 and 3,
respectively, in Figure 4.
C. Connect iPort (supplied with the AFBR-800EVK but
NOT supplied with the AFBR-800EVB) to 4 in Figure 4 to
communicate to the DUT using a Host computer;
Communicate to the device using a USB to iPort device
and iPort Message Center or the MIniPOD Graphical
User Interface (GUI)
D. If using a TX MiniPOD, apply electrical input transmit-
ter data, from a Bit Error Rate Tester or other suitable
source, to side mounted SMA connectors 0 through 11.
Alternatively, if using an RX MiniPOD, connect these
electrical outputs to an electrical Digital Communications Analyzer or Error Detector. Note that these are
high speed di erential signals.
E. To measure Optical output parameters, after
the Prizm-to-MTP cable (supplied with the
AFBR-800EVK but NOT supplied with the AFBR800EVB), use a break out cable with MTP-toFC/SC/ST connectors.
F. To establish a full link, connect the Prizm-to-MTP cable
(supplied with the AFBR-800EVK but NOT supplied
with the AFBR-800EVB) to another MiniPOD module
(transmitter to receiver). Alternatively connect the
MTP connector to a compatible module, such as an
Avago CXP transceiver AFBR-83PDZ. For either link
con guration an intermediate MTP female to MTP
female cable must be used, because the Prizm-toMTP cable is a male termination as is the termination
at the input of a CXP module. Also note that the
MTP female to MTP female cable must be ipped in
polarity to properly align the TX to RX bers, and this
is achieved using an MPO adapter (Molex part number
1061141200) that features a key-up input with a keydown output. Alternatively a female MTP to female
MTP cable may be used with a key-up / key-down
polarity.

G. SMA connectors 0 through 11 are used for either
electrical input or electrical output signals depending
on whether the DUT is a Transmitter or Receiver
MiniPOD module. Note that these are high speed
di erential signals.
H. Measure Optical Receiver output parameters using
SMA cables to an electrical Digital Communications
Analyzer.
