OTDR Overview
Introduction:
The OTDR Module allows you to test the integrity of a fiber cable and is used
for the building, certifying, maintaining, and troubleshooting of fiber optic
systems. It builds a virtual image of the tiber optic cable to determine the
condition and performance of the fiber and displays any events that may occur.
Function Keys:
- F1: Enter the Settings of the OTDR.
- F2: Switch between the A and B cursors.
- F3: Saves the data being displayed.
- F4: Open a specified file or folder.
Other Keys:
- Directional Keys: Use the Directional Keys to move the A and B cursors.
- Zoom Key: Press the Zoom key to enter Zoom mode. Press the left or right directional buttons to zoom in or zoom out of the data.
- Measure Key: Press the Measure Key to begin the OTDR test.
- Exit Key: Return to the Main Menu interface.
Setting Up theOTDR
Press the F1 key to enter the settings of the OTDR, and use the Directional
Keys to choose the parameters you want to change.
There are several settings that can be adjusted:
Note: The function keys will not work while changing the parameters.
Wave
Choose the wavelength you want to test, either 1310 nm or 1550 nm.
Mode
There are 3 mode settings to choose from:
- Auto-Test: Automatic test that adjusts the Range and Pulse automatically to give the best possible view of events on the fiber cable being tested.
- Real-Test (Real Time/Live Mode): Live tests the fiber using the set parameters. This allows the end-user to view the signature trace in live active mode, providing a quick verification of the installation/restoration made. While testing in this mode, press the Measure key to stop testing.
- Avg. Test: Tests the fiber cable using the set parameters. In this mode, you can manually set the Range and Pulse. If the Auto-test does not correctly identify the
events, use this mode using a longer range and/or different pulse setting.
Setting Up the OTDR
Range
The Range is the maximum distance shown on the trace. Select the range that is
nearest to, but not less than, the distance to the event you want to evaluate.
If the tester does not correctly identify the end event, select the next
higher range and retest. The Range can be set from 500 m (0.31 mi) to 64 km
(39.77 mi).
Pulse
Adjust the pulse width to a larger width to see farther down the fiber or to a
shorter width for better resolution. Shorter pulses allow you to see
reflective events in more detail and help you see hidden events, which may not
appear when using a larger pulse width. However, shorter pulses reduce the
range of the OTDR and create more background noise between events. When using
shorter pulses, small loss events could be hidden in the noise on the trace.
Pulse With is directly related to distance and resolution. The greater the
distance and more events within the trace your viewing, a larger pulse width
is selected. Therefore, larger pulse widths allow one to see further down a
fiber. Shorter distances and loss events will require a shorter pulse width to
be selected, to avoid oversaturation of trace details which improves
resolution to see events in greater detail.
However, shorter pulse widths reduce the OTDR’s dynamic range and create more
background noise between events. With the correct pulse width selected, end-
users will avoid events being hidden, over expanded, repetitive events that do
not actually exist, as well as other inaccurate event/trace results.
Larger pulses increase the backscatter signal level, which gives a better
signal-to-noise ratio around non-reflective events. This is used to see
smaller loss events and measure their loss more accurately. However, using
larger pulses increases the dead zones of events and can hide small
reflections. The pulse width can be adjusted from 3 ns to 160 ns.
Note: When using Auto-Test mode, the OTDR module will automatically
adjust the Range and Pulse to be as short as possible, giving the best
possible view of events.
Avg. Time
The averaging time is the amount of time the tester takes to make measurements
to calculate the averages of the measurements. Longer average time has less
noise, increasing the dynamic range and accuracy of the results, and it allows
you to see small events more clearly, such as splices. The Avg. Time can be
adjusted from 5 s to 180 s.
Setting Up the OTDR
Event Loss Thre.
Set the Event Loss Threshold for loss or non-reflective events. Events that
are at or above this threshold are recorded in the event table for evaluation.
The Event Loss Threshold can be set from 0.01 dB to 9.0 dB.
Return Loss Thre.
The OTDR-1000 returns the ORL (Optical Return Loss) by calculating the total
of all light reflected from reflective events plus the total backscatter from
the entire length of fiber being tested. This ORL measurement is sometimes
used as a specification for very high speed systems, as ORL can be a
contributor to noise in a transmission link. In most situations, the Return
Loss Threshold is set at 40 dB and should not be changed.
End Loss Thre.
Set the threshold to detect the end of the fiber cable being tested. An event
that is above the threshold is shown as the end of the fiber. The End Loss
Threshold can be set from 0 to 99 dB.
lor
lor or Index of Refraction calculates the total length of the fiber being
tested. Optical length may differ from the length of the fiber jackets in a
link due to curves and small variations in the lor of the fibers. Each fiber
type includes a default lor value, specified by the manufacturer. Set the lor
to this value before testing. lor can be adjusted from 1.000 to 1.999.
Function Keys
While in the Settings menu, the function keys perform different tasks:
- F1: Test: Run a test using the parameters that are set.
- F2: Okay: Set the thresholds and return to the main OTDR screen.
- F3: Recover: Reset to factory settings.
