2.1 Setting
Under the main interface of the OTDR, press the [Parameter Settings] button to quickly enter the
Test Parameter menu:
“
Test parameter
”
Menu
2.1.1 Test Parameter
Wavelength: 1310nm, 1550nm.
Measuring range:
-AUTO mode: The device will automatically set the most appropriate parameters for the
current measurement including the measurement range and pulse width. Auto selected
values cannot be modified in this setting.
-Manual mode: The range and pulse width can both be set manually.
Pulse Width: Pulse width refers to the time width of emitting laser signal during measurement.
The wider the pulse width is, the stronger the optical power injected into the fiber, the
stronger the backscattering signal of the fiber, and the farther the OTDR can effectively detect,
but a wide pulse width will cause saturation of the initial reflection signal, resulting in larger
deadzone. Therefore, the selection of pulse width is related to the measurement of fiber
length. The longer the length is, the wider the pulse width. It can not be modified in the
automatic measurement mode, which defaults to "automatic configuration".

ATLAS MINI OTDR User guide

Measuring time: In the mean measurement mode, the longer the detection time is, the better
the signal-to-noise ratio is improved, and technician receives more accurate the test results.
The user should reasonably select the detection time, which is proportional to the dynamic
measurement.
Resolution: High resolution will have more sampling points and higher accuracy, but it will also
increase time of test due to amount of data collected.
Refractive index: Is the essential characteristics of optical fiber, different manufacturers of
optical fiber have slightly different refractive index which is the key parameter to calculate the
distance, this value cannot be arbitrarily set.
Unit: Kilometer/Kilofeet/Miles.
OTDR will automatically select the most appropriate reference pulse width when manual
measurement range is set in automatic mode.
The range and pulse width can be adjusted manually in manual mode. The following list is for
reference only:

Various event measurement thresholds, including attenuation/reflection/slope/optical fiber end
refractive index and scattering coefficient settings.
The refractive index is selected by the user and changing the refractive index setting will change
the ranging result. The refractive index is provided by the fiber optic cable or fiber optic
manufacturer. Users are advised to calibrate the group refractive index with a known length of
fiber and remember it.
The scattering coefficient is usually obtained from the fiber optic cable manufacturer.

Under no circumstances shall the optical interface and the end of the tail fiber connected to the
optical interface be directed to the eye of the operator or other person. Otherwise, the eyesight
of the irradiated person can be damaged.

File operation
The menu provides a complete file storage call out function. The results of each measurement are
automatically saved to internal storage (configurable) and marked with time, date, serial number
and other information for easy reference. Users can name, number, comment on each

2.4 Graphical Event Map
Graphical event maps can be used to assist in viewing and troubleshooting fiber links for new technicians.
The event map translates the connection of the whole fiber link directly into the physical schematic
diagram, such as fusion splice connection, connector pair connection, optical splitter, launch and receive
fibers and macro-bends.
Some analysis parameters need to be set before using graphical event map measurements (the OTDR has
default classical values, if the user is not familiar with the link analysis parameters, it is recommended to
use the default values directly).
Event map
2.4.1 Pass/Fail Threshold
The pass/fail threshold parameter is used to judge whether the splice junction and connector pair connection
point are within the qualified range or exceed the threshold parameter. The schematic diagram shows red, is
values exceed threshold parameter, or green if the values are acceptable within parameters.

2.4.2 Splitter loss Settings
In a PON network there is usually 1 x N splitters, but the loss of each splitter may be different. Therefore it is
necessary to limit the loss value of the splitter. If the value range is set incorrectly, the accuracy of the event
map will be affected.
