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.

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.
