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.
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.
Fiber optic testers vary from other types of test equipment due to issues such as:
1) standards-based testing
2) proper fiber optic test procedures (FOTPs)
3) "zeroing" or referencing of power levels
4) determining the correct link budget to pass or fail by
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
Tells the user some useful information about the successful completion of a procedure
Warns the operator of a potentially dangerous condition

INTRODUCTION
Fiber OWL7+ certification test kits include a Tier 2 certification meter and light source that enable fiber optic professionals to perform a
wide range of tests, from basic optical power/loss measurement all the way up to full-featured Tier 2 certification (PASS/FAIL and
OTDR trace results) for their clients.
Models are available that can test multimode only, singlemode only, or both multimode and singlemode. Optional accessories such
as OTDR fiber rings and video inspection microscopes are also available to take full advantage of Tier 2 certification capability.
Fiber OWL 7+ certification power meter. Test readings and graphical help screens can be easily viewed on the color LCD, and an
intuitive 10-key keypad allows for easy data entry.
The intuitive built-in Link Wizard prompts the user to enter key information used to calculate standards-based link budgets for fiber
optic certification testing, and helpful diagrams guide the user through the setup and testing procedure.
Thousands of data points tored information can be
selectively viewed, re-tested, or deleted from the device.
WaveSource Pro fiber optic light source. An intuitive 4-button keypad controls key functions such as port and wavelength
selection, and a 7-segment LED displays the currently selected wavelength.
Both the meter and source are enclosed in attractive hand-held cases made from high impact plastic and protected by a protective
rubber boot, and are powered by re-chargeable lithium polymer batteries which are re-charged through a USB port via a supplied
battery charger and cable.
Following is a short description for each of the functions that can be performed with these devices, which will be covered in more detail
later in this manual.
with descriptive link and fiber run labels can be stored in internal memory. S
DESCRIPTION
APPLICATIONS
Transmitter Power Measurement (OPM MODE). The Fiber OWL 7+ meter can be used as a basic power meter (OPM) to measure
the output power of active equipment transmitters, which is useful for two different purposes:
The output power of the transmitter can be measured by connecting the meter directly to the transmitter port; and
The transmitter power can also be measured through the link, which is helpful for determining if the received power of the
equipment at the far end is within the equipment’s receiver sensitivity range.

INTRODUCTION
APPLICATIONS, cont.
Checking patch cables (OPM MODE). As an optical power meter (OPM), the Fiber OWL 7+ is also useful for performing a quick
check of patch cables, to ensure that the patch cables are okay to use for testing (when connected to the output of the NIST calibrated
light source).
And, assuming the patch cable is good, users can periodically monitor the NIST calibration levels of the light source outputs and
power meter detector to make sure they are within the device specifications.
OTDR Measurement. Using the OTDR in Fiber OWL 7+ fiber certifiers, users can acquire a trace of events for the purpose of
characterizing the network or troubleshooting for problems, as well as determine the end to end length of the fiber link.
Visual Fault Location. The Fiber OWL 7+ contains a visual fault locator port used for quick troubleshooting of optical faults close to
the near-end of the optical fiber under test, or for visually identifying fibers (up to 5km in typical fiber links).
The 2.5mm universal VFLport is located on the left-hand side on the top of the OTDR.

INTRODUCTION
APPLICATIONS, cont.
Attenuation (Optical Loss) Measurements (LOSS MODE). After a fiber cable has been installed and terminated, optical loss
measurements can be used to determine if the fiber is installed according to standards and specifications. Acomparison between the
actual power measurement and the reference value determines how much optical power is lost through the link.
Fiber Optic Link Certification (CERT MODE). Certify individual optical fibers at up to two wavelengths simultaneously. The Link
Wizard in the Fiber OWL 7+ uses attenuation parameters from popular cabling standards to certify fiber links, and shows a link’s
PASS/FAILstatus right in the field.
TIER 2 Certification (FULL MODE). Tier 2 certification is defined in the TIA-568 cabling standard as a way to give end users a more
comprehensive set of test results. Tier 2 certification combines traditional certification test results (i.e. Tier 1) with OTDR test results.
The Fiber OWL 7+ includes a test mode called FULL mode that guides the user through the Tier 2 certification process – first, all fibers
are tested with the OTDR, then certification results are added once all the OTDR traces have been taken.
OWLView software enables users to download FULL MODE test results into one convenient project file, and both sets of results
conveniently appear on printed test reports and PDFs.

INTRODUCTION
PRECAUTIONS
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
look into the connector port of a light source or the end of a fiber.
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.
Light Source Connector - Do NOT insert APC (Angled Physical Contact) connectors into any light source or OTDR port on your
Fiber OWL7+ or WaveSource Pro as this may damage the angled ferrule on theAPC connector.
NEVER
On the back of each unit included with Fiber OWL 7+ series fiber link certifiers are labels similar to the one shown below containing
model number, serial number, power requirements, and special cautionary information.

OVERVIEW
TEST PROCEDURES
OPM MODE
Optical power is an absolute measurement of the amount of light intensity; i.e. “brightness”, and is one of the
most basic tests performed by an optical power meter (OPM). The Fiber OWL 7+ contains a basic OPM MODE
for this purpose.
APPLICATIONS
OPM MODE enables users to perform the following basic tests:
Transmitter power measurement
Receiver sensitivity measurement
Checking patch cables
Verification of NIST calibration levels
Basic optical loss measurement
OPM MODE is indicated at the top of the display.
Since OPM MODE is designed for basic power and loss
measurements only, data storage functions are not
available.

If patch cable measurements are within specifications, the user has verified that: 1) the patch cable is good;
and 2) the units are measuring within their calibration levels.
Connect the patch cable to be tested between the OPM port on the Fiber OWL 7+, and the appropriate
source port on the WaveSource Pro.
Hold – set the WaveSource Pro to AUTO mode
– set measurement units to dBm
Both available wavelengths should appear on
the Fiber OWL 7+ display.
Light source calibration levels ( ):
Singlemode: -10.00 dBm
62.5/125 multimode: -20.00 dBm
50/125 multimode: -23.00 dBm
actual measurements values may be slightly above or below
light source calibration levels, but should be close

Setting a reference
(aka “zeroing”)
Sets a baseline optical power
level between a power meter
and light source prior to
taking measurements.
The difference between this
reference level and the
link power measurement
is called optical loss.
You must set a zero reference
before testing. Do you wish
to do it now?
YES NO
