Low Speed signals:
Depicted in Figure 5 are:
1. Reset button
2. Transmit modules will respond to TWS bus addresses
in the range of 50h to 5Fh depending upon the state
of Adr2, Adr1 and Adr0. Similarly receiver modules will
respond to addresses in the range of 60h to 6Fh.
3. Monitor points for the SDA, SCL, and Intl (directly from
the MiniPOD module)

MiniPOD Test Setup
Basic Operating Instructions for MiniPOD module Device
Under test:
A. Insert the MiniPOD (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 Communica-
tions Analyzer or Error Detector. Note that these are
high speed diff erential signals.
E.
To measure Optical output parameters, after
the
Prizm-to-MTP cable (supplied with the
AFBR-800EVK but NOT supplied with the AFBR-
800EVB),
use a break out cable with
MTP-to-
FC/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
confi guration an intermediate MTP female to MTP
female cable must be used, because the Prizm-to-
MTP 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 fl ipped in
polarity to properly align the TX to RX fi bers, and this
is achieved using an MPO adapter (Molex part number
1061141200) that features a key-up input with a key-
down 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
diff erential signals.
H. Measure Optical Receiver output parameters using
SMA cables to an electrical Digital Communications
Analyzer.
