Working Principle
The OTDR’s operating principle is based on the measurement of the Raleigh
Backscattering Signal, generated by sending a high power optical pulse from the
OTDR through the optical fiber. Light is reflected back to the OTDR. This
backscattered light is measured by the sensitive optic receiver, converted to digital
form and averaged to improve the signal to noise ratio. The resulting signal forms
a graph called a TRACE. The trace is a visual representation of the backscattering
coefficient created by the OTDR to determine the “events.” The trace shows the
“events” on the fiber optic link such as breaks, splice loss, bends, attenuation and
distance.
OTDR Distance Calculation Formula
Distance = c * t / ( 2 * n )
c = speed of light in a vacuum
n = index of refraction of the fiber under test
Time delay between pulse emitted

GETTING STARTED
Preparation for work
The device maybe operated when powered by the external 12V AC/DC adapter or
separately by the internal battery, once the battery is charged to an acceptable
operational level. If the unit is being charged by the external 12V power supply
both the green “BATTERY” LED and the orange “CHARGE” LED on the face panel
will illuminate. The fiber to be tested is connected to the OTDR’s optical connector
on the front panel of the unit. It is recommended to always use a launch cable
when using an OTDR but it is not necessary. If testing the cable directly with the
OTDR the cable connector style must match the OTDR output connector. Power
Meter optical port offers versatility with removable connector adapters. All OTDR
connector ports and test cables should be kept clean and free of dust and dirt for
optimal unit operation.
Powering On/Off unit
The unit is powered On or Off by pressing and holding the
button for several
seconds.
When the unit is powered on the green LED on the face panel will illuminate.

Parameters
•
Wavelength - For Multimode 850nm or 1300nm and for single mode
1310nm, 1550nm or 1625nm.
• Distance Range, Km - The maximum value of the measured distance. The
value of the distance range should exceed the length of the line under test
by more than 20%.
• Pulsewidth, ns – This determines the value of the optical pulse duration.
The range of the acceptable optical pulse value is dependent on the chosen
Distance Range and is automatically limited by the OTDR program.
• Resolution, m – This determines the distance between two samples
(sampling intervals) of the trace. The value is dependent on the Distance
Range.
• Measurement Time, Min/Sec – This determines the duration of the
measurement process with averaging. Live mode performs fiber monitoring
in real time mode.
• High Resolution - In this mode the optical receiver bandwidth is increased.
Best used when testing a short cables and requiring excellent dead zone – do not use on
long fiber lengths than require high dynamic range.
Note: To have the unit Auto Select the parameters press Auto Setup. The program
will perform a short measurement on the connected fiber and automatically define the
optimal parameters for that fiber. The technician can then modify the parameters
manually if desired and run a measurement

Backscattering Coefficient, BC – represents the level of backscattering in
a particular fiber. It is used for Reflectance and ORL measurement and can
be obtained from the fiber manufacturer. This parameter value can be stored
for any saved trace.
Refractive Index – (also known as group index) is used to convert time to
distance. For precise distance measurement it is important that this value is
accurate and can be obtained from the fiber manufacturer. This parameter
value can be stored for any saved trace.
Automatic Trace Analysis Threshold – have the following selectable
features
o Splice Loss, LT – threshold of the event attenuation value in dB.
Events with attenuation value that exceeds the threshold value will be
shown in the Events Table.
o Reflectance, RT – threshold of the event reflectance value in dB. The
reflected event having a reflectance higher than the threshold value
are shown in the Events Table.
o End-of-Fiber, ET – threshold of the event attenuation value in dB for
defining the fiber end. The first event with an attenuation exceeding
the threshold value is defined during the automatic trace analysis as
an optical fiber end. All subsequent events will be ignored.
o Attenuation, CT – Attenuation coefficient threshold value of the
section in dB/km. Exceeding the attenuation coefficient threshold value
will mark the section with an * in the Event Table.

Manual Measuring Modes
Using the Markers
Measuring Attenuation between two marker
points - (2 PT)
In this markers mode values are shown at the bottom of
the screen in the horizontal information panel. The
measurement values are based upon where the left hand
marker (A) and right hand marker (B) are positioned on
the trace screen. The dB field in the information panel
displays the attenuation between the left and right hand markers, while the
dB/km field displays the attenuation coefficient.
Measuring the Attenuation by Approximation - (LSA)
The attenuation measurement by approximation mode is
used to measure “non- event” sections of the fiber optic
link. This mode increases the accuracy of the attenuation
measurement between the two markers by using a
straight line to approximate the measurement. The
approximation straight-line measurement values are
shown at the bottom of the screen in the horizontal
information panel. The measurement values are based
upon where the left hand marker (A) and right hand marker (B) are positioned on
the trace screen. The dB field in the information panel displays the attenuation
between the left (A) and right (B) hand markers, while the dB/km field displays
the attenuation coefficient.
Attenuation Measurement of an “Event” – (Splice)
Using the “Five Markers” method the OTDR measures the
attenuation of a specific event. The “five marker” method
works as follows
The left marker (A) and right marker (B) are placed on
either side of the event, as close as possible to the edges
of the event, without touching the event itself. The two
outermost markers (a and b) are used to calculate the
straight line approximation of the fibers on both sides of
the event and the fifth marker (c) is used to locate the begining of the event. The
measurement results are displayed in the horizontal information panel. The Spl,
dB field in the information panel displays the attenuation of the event while the

Reflective Coefficient Measurement - (Reflection)
This marker method is used to measure the reflection
coefficient of a specific connector event. Place the right
marker (B) on the peak of the reflected event. Place the
left marker (A) on the base line of the trace directly
before the event. The measurement results are displayed
in the horizontal information panel. The Refl, dB field
displays the reflective coefficient between markers A and
B while the Refl, km field displays the left (A) marker
and location of the base of the connector.
Optical Return Loss - (ORL)
This marker method measures the Optical Return Loss of a partial fiber section or
the whole fiber link
Place the left (A) and right (B) markers on the fiber link that is being tested. The
measurement results are displayed in the horizontal information panel. The dB
field in the information panel displays the attenuation between the left (A) and
right (B) hand markers while the ORL, db field displays the ratio (in dB) of the
optical power entered into the fiber link verses the power which is returned to the
beginning of the fiber.
