INTRODUCTION
BEFORE YOU BEGIN
All personnel testing optical fibers should be adequately trained in the field of fiber optics before using any fiber optic test equipment.
Fiber optic testers vary from other types of test equipment due to issues such as:
1) standards-based testing
If the user is not completely familiar with testing fiber optics, they should seek competent training. Such training can be acquired from
a variety of sources, such as local hands-on training classes.
Valuable information about fiber optic testing can also be gathered from reading printed literature carefully or by thoroughly reading
supplied operations manuals.
3) "zeroing" or referencing of power levels
4) determining the correct link budget to pass or fail by
2) proper fiber optic test procedures (FOTPs)
Complete understanding of each of these issues is critical for performing proper fiber optic tests.
Throughout this manual you will find various symbols that assist with understanding the procedures outlined in this manual. Below is
a list of these symbols and a short description of their purpose:
Shows a helpful tip that will make a procedure go more smoothly
Warns the operator of a potentially dangerous condition
Tells the user some useful information about the successful completion of a procedure
ABOUT THIS MANUAL

INTRODUCTION
OWL optical switches enable fiber optic technicians to use their traditional single-fiber testers, such as OTDRs, VFLs, power meters,
TM
and light sources to conveniently test 12-fiber MPO/MTP cabling without the need for bulky, confusing, and expensive breakout
cables or cassettes. Models are available for multimode or singlemode fibers.
MPO optical switches act as a sort of “traffic cop”, re-directing the optical signal from the input port to a specific MPO channel. MPO
channel selection is manually controlled via channel up / channel down buttons, allowing users to target specific MPO channels to be
tested. Channel number is indicated by a bright, easy-to-read 7-segment LED display.
The MPO optical port is covered by a shuttered dust cover, in order to prevent debris from collecting in the MPO port.
The optical switches are powered by a re-chargeable Lithium Polymer battery, allowing for hours of continuous use on a complete 12
charge. The battery is charged via supplied USB charger and cable, and a battery indicator LED indicates low battery and charging
status.
OWL optical switches are also equipped with Bluetooth, allowing them to communicate wirelessly with certain Bluetooth-enabled
OWL power meters and OTDRs. While in AUTO mode, the OWL tester will tell the MPO switch to the next MPO channel to test.

INTRODUCTION
PRECAUTIONS
Operational - It is important to keep connector ferrules and optical connector ports clean. If dirt, dust, and oil are allowed to build up
inside connector ports, irreparable damage may occur to the optics inside the port. For best results, replace dust caps after each use.
Input Connector - Do NOT insert APC (Angled Physical Contact) connectors into the input port of the MPO switch as this may
damage the angled ferrule on the APC connector.
Safety - Exercise caution when working with any optical equipment. High-intensity fiber optic laser sources output potentially
dangerous high energy invisible light, and could cause serious, irreparable damage to the eye. Thus, it is recommended to NEVER
look into the connector port of a light source or the end of a fiber.
On the back of each DataCenter 12 MPO Optical Switch are labels similar to the one shown below containing model number, serial
number, power requirements, and special cautionary information.

OTDR TESTING
APPLICATIONS

STEP 3 Set the MPO switch to the MPO channel that corresponds to the specific MPO fiber to be tested. Usually this will be MPO
switch Channel 1 when testing all of the fibers in the MPO cable
Testing 12-fiber MPO cables with an OTDR and DataCenter 12 MPO Optical Switch
STEP 1 Power ON both the OTDR and the MPO Switch.
STEP 2 Connect the OTDR and optical switch to the MPO cable under test using the accessories as shown below.
SC/UPC-SC/UPC patch cable (ensure correct fiber type)
25-meter MPO OTDR launch cable (ensure correct fiber type; use Type B)
MPO adapter (Type B)
OPTIONAL: if you want to include the far end MPO connector in the OTDR test, attach another MPO adapter ( ) and MPO OTDR
launch cable ( )to the end of the MPO cable under test
However, based on the polarity of the MPO cable under test, please be aware that the fibers may or may not be numbered the same on
the opposite end of the MPO cable. Take this into account when testing in the opposite direction.
Repeat Steps 4 and 5 until all fibers in the MPO cable have been tested.
IMPORTANT NOTE: the MPO cable under test will typically be tested from the right-most fiber (Channel 1) to the left-most (Channel
12) as seen from the perspective of the near-end MPO connector.
STEP 4 Run the OTDR test, and save the results.
STEP 5 Press the UP arrow button ( ) to change to the next channel.

Testing 12-fiber MPO cables with a Visual Fault Locator and DataCenter 12 MPO Optical Switch
STEP 1 Power ON both the VFL and the MPO Switch.
SC/UPC-SC/UPC patch cable (ensure correct fiber type)
STEP 2 Connect the VFL and optical switch to the MPO cable under test using the accessories as shown below.
STEP 3 Set the MPO switch to MPO switch Channel 1
IMPORTANT NOTE: based on what type of MPO cable is being tested, the light from MPO Channel 1 will appear in different places at
the far end. This is helpful to visually verify the polarity of the cable under test. See diagram below for common standards-based MPO
polarity arrangements.
For example, when the MPO optical switch is set to Channel 1, the light will be seen on Fiber 1 for Type A, Fiber 12 for Type B, and
Fiber 2 for Type C.
STEP 4 Press the UP arrow button ( ) to change to the next channel.
