INTRODUCTION
BEFORE YOU BEGIN
All personnel testing optical bers should be adequately trained in the eld of ber optics before using any ber optic test
equipment.
If the user is not completely familiar with testing ber 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 ber 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 ber 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 ber optic tests.
ABOUT THIS MANUAL
Throughout this manual you will nd 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
DESCRIPTION
The Fiber OWL 7 BIDI is a high-accuracy, high-resolution, microprocessor-controlled optical loss test sets (OLTS) capable of
performing a wide variety of testing applications, from basic optical loss measurement up to simultaneous bi-directional, dual-
wavelength ber link certication. With a wide measurement range and NIST-traceable wavelengths, the Fiber OWL 7 BIDI is ideal
for both singlemode and multimode ber link certication.
Enclosed in an attractive hand-held case made from high impact plastic and protected by a protective rubber boot, test readings
and graphical help screens can be viewed on the color LCD, and an intuitive 10-key keypad allows for easy data entry.
Each Fiber OWL 7 BIDI is powered by re-chargeable lithium polymer batteries, typically allowing up to 50 hours of continuous use.
A built-in auto-shutdown feature further conserves battery life. Batteries are re-charged through the USB port via supplied battery
chargers.
The intuitive built-in Link Wizard prompts the user to enter key information used to calculate standards-based link budgets for ber
optic certication testing, and helpful diagrams guide the user through the setup and testing procedure.
Thousands of data points with descriptive link and ber run labels can be stored in internal memory. Stored information can be
selectively viewed, re-tested, or deleted from the device.
The data can also be downloaded to OWLView certication software to produce professional-looking formatted certication reports.
OWLView software includes a “tri-report” option that integrates power meter certication, OTDR traces, and endface analysis
results all on the same report (separate ber microscope and OWL OTDR required for tri-report).

APPLICATIONS
PAIR MODE
Fiber Optic Link Pair Certication. PAIR mode is the fastest, easiest, and most innovative way to certify a ber pair at up to two
wavelengths simultaneously, including length measurement with each test, since bi-directional testing is not required by cabling
standards; i.e. test direction does not matter.
PAIR mode is twice as fast as bi-directional link certication and much less confusing.
Testing bi-directionally requires a two-step process: test in one direction, swap ber ports, then test in the other direction. PAIR
mode cuts testing time in half by eliminating the second (not required) direction, and keeps things simple by eliminating the often-
confusing and error-prone step of swapping ber ports.
PAIR mode is twice as fast as traditional link certication.
Traditional link certication certies one ber at a time. PAIR mode tests two bers at a time, signicantly speeding up the
certication process. In addition, PAIR mode allows length measurement with each test, something that traditional link certication
cannot do.
The Link Wizard in the Fiber OWL 7 uses attenuation parameters from popular cabling standards to certify ber links, and shows
complete PASS/FAIL test results for both bers at both wavelengths, all on the same screen, right in the eld.

APPLICATIONS
BIDI MODE
Bi-directional (BIDI) Fiber Optic Link Certication. Similar to PAIR mode, BIDI (bi-directional) mode allows users to quickly
and conveniently certify a ber pair in both directions at up to two wavelengths simultaneously, including length measurement with
each test. Keep in mind that while bi-directional testing is not a requirement of cabling standards, it may still be required by the
end user.
The Link Wizard in the Fiber OWL 7 uses attenuation parameters from popular cabling standards to certify ber links, and shows
complete PASS/FAIL test results for both bers at both wavelengths, all on the same screen, right in the eld.

APPLICATIONS
CERT MODE
Traditional Single-ber Link Certication. When the remote is set as a stand-alone light source (or a separate stand-alone source
is available), CERT (certication) mode allows users to certify individual optical bers at up to two wavelengths simultaneously.
The Link Wizard in the Fiber OWL 7 uses attenuation parameters from popular cabling standards to certify ber links, and shows
a link’s PASS/FAIL status right in the eld.

APPLICATIONS
LOSS MODE
Attenuation (Optical Loss) Measurements. After a ber cable has been installed and terminated, optical loss measurements can
be used to determine if the ber is installed according to standards and specications. A comparison between the actual power
measurement and the reference value determines how much optical power is lost through the link.
Loss mode requires the remote to operate as a stand-alone light source, or another stand-alone light source.

APPLICATIONS
OPTICAL POWER MEASUREMENT
Optical Power Measurements. Optical power is an absolute measurement of the amount of light intensity; i.e. “brightness”, and
can be measured either at the output of a transmitter (transmit power), or at the input of a receiver (receiver sensitivity). When in
OPM mode, the Fiber OWL 7 can be directly attached to this equipment via a patch cord to check whether the transmitter is within
the manufacturer’s specied power range.
