INSTRUCTIONS

When the automatic test is selected, the fiber is automatically analyzed, and a list of events is given when the test stops.

After curve analysis, event points where the connection loss is greater than the loss analysis threshold will be marked. Event points where the connection loss is less than the loss analysis threshold are automatically ignored.

In the event list, connection loss and reflection loss greater than the set threshold will be marked with an asterisk (*).

When the connection loss of the event point is greater than the threshold value of the fiber break point, the event point is considered as the fiber break point. All events after this event point are ignored and not shown in the list.

Click the [Set] button, then click the [Link Definition] button to set the link thresholds, as shown below:

TESTING THE FIBER LINK

The operation steps are as follows:

1. Select the test wavelength.
2. Set test conditions such as test wavelength mode.
3. Clean the end-face(s) of the fiber connectors to be tested.
4. Connect the test fiber to the corresponding OTDR optical input port.
5. Press the test key to obtain the waveform curve of the tested fiber.
6. After testing:

- If [Auto Test] mode or [Auto Analysis after Sampling] is selected, the OTDR-1500 will automatically analyze the test curve, mark the event points according to the set loss analysis threshold, and give the event list.

- Otherwise, click the [Analysis] button in the main menu bar. The OTDR-1500 will analyze the test curve, mark the event points according to the set loss analysis threshold, and give the event list.

1. After curve analysis is complete, test results can be viewed in the event list.

OTDR MODULE TEST MODES

The OTDR module has two test modes: Automatic Test and Manual Test modes.

1. Automatic Testing

When the OTDR test mode is set to Automatic Test:

After the test key is pressed, OTDR-1500 will automatically adjust the test conditions to test the connected fiber link. After the test is completed, curve analysis will be performed automatically, and the test curve and event list will be displayed in the main operation window.

2. Manual Testing

When the OTDR test mode is set to manual test:

After clicking the [Real-time] button in the main menu bar (at this time, the content on the [Real-time] menu button changes to [Stop]), the OTDR will conduct a real-time scanning test on the fiber link according to the set parameters. During this time, the test curve in the main operation window will be constantly refreshing.

When the OTDR test mode is set to manual test:

After pressing the test key or clicking the [Average] button in the main menu bar (at this time, the content on the [Average] menu button changes to [Stop]), and the OTDR will average the test results of the fiber link according to the set parameters. The test curves in the main operation window will be averaged continuously, until the average time displayed on the interface equals the set average time, in which the OTDR will stop testing.

In the automatic test mode, after testing, the device will analyze the test curve and give a list of events. In other test modes, the device can automatically analyze the test curve only when the [Post-test analysis] function is selected. Otherwise, you must click the [Analysis] button in the main menu bar to analyze the curve and then give a list of events.

TEST PARAMETERS OF THE OTDR MODULE

OTDR test parameters include wavelength, range, pulse width, average time, refractive index, and the fiber optic cable correction factor.

1. Wavelength:

Wavelength is used to set the test wavelength of OTDR. The OTDR module can be set to 1310 nm and/or 1550 nm wavelengths.

Multiple wavelengths are allowed to be selected simultaneously in average test and automatic test mode. To do so, click [Setup], then [Mea. Par.], check the 1310 and

1550 checkboxes, and click [Enter]. During the test, the device will test at each selected wavelength in turn until all the selected wavelengths have been tested.

2. Measuring range (km):

Measuring Range is used to set the curve range of the test. The range of the optical time domain reflectometer is divided into the following stages: 400m, 800m, 1.6km, 3.2km, 8km, 16km, 32km, 64km, 128km, 256km and 512km (the maximum optional range is related to the selected module).

IMPORTANT: The measuring range must be larger than the length of the fiber under test (preferably larger than twice the length of the fiber under test).

3. Pulse width (ns):

Pulse width is used to set the width of the laser pulse to be used during the test. Larger pulse widths should be used to test longer fiber. The signal-to-noise ratio of the test curve is better, the curve is smoother, but the resolution is not as good.

Smaller pulse width has a higher resolution, but the measurement distance is shorter, and the signal-to-noise ratio the test curve is not as good.

4. Average time:

Average time is used to set the maximum average time for average testing and automated testing. In both modes, the time values are 15, 30, 45, 60, 90, 120 and 180 seconds.

5. Refractive index:

The refractive index of an optical fiber cable can be obtained from the manufacturer of the cable. The refractive index should be set to that parameter, between 1.00000 \~ 2.00000.

6. Cable correction:

The fiber optic cable correction factor is the error between the change of fiber length and the length of the fiber after the fiber optic cable is considered. This parameter may be needed and is available from individual fiber optic cable manufacturers. Its value can be set to 0.80000 to 1.00000, and the default value is 1.00000.

7. Lock markers A and B:

When this option is selected, the distance between marker A and marker B is locked. When either marker is moved, the two markers move together, keeping the distance between them the same. If this is not selected, when one marker is moved, the other one remains in its original position.

8. High resolution test:

When this option is selected, the maximum number of sampling points of the instrument is increased to 256k, which enhances the resolution of events occurring within a short distance.

OTDR TEST RESULTS

OTDR test results can be selected as follows: average loss, connection loss and reflection loss. You can click the control arrows to switch between these test items.

1. Average loss

- Shows the loss, distance, and average loss of the optical fiber between markers A and B.

2. Connection loss

- Shows the connection loss of the fiber at marker A.

3. Reflection loss

- Shows the reflection loss of the optical fiber, the reflection peak where markers A and B are, and the distance between markers A and B.

IMPORTANT

• When testing the average loss, markers A and B must be set on the linear section of the curve, otherwise the calculated average loss will not be correct.
• When testing connection loss, four markers appear in order: marker a, marker A, marker B, and marker b. Set marker a and marker A on the linear

segment of the fiber curve, before the connection point. Marker A should be set near the join point, and marker B and marker b should be set on the linear segment of the fiber curve after the connection point.

- When testing the reflection loss, set marker A in front of the reflection peak to be tested and near the take-off point of the reflection peak. Set marker B on the top of the reflection peak to be tested.

EVENT ANALYSIS & PASSING THRESHOLD

On the OTDR test condition setting interface, you can set the event analysis and passing threshold.

1. Loss analysis threshold

- When analyzing the test curve data, if the calculated connection loss of the event point is greater than the loss analysis threshold, the event point will be marked with an asterisk. Otherwise, it will be automatically ignored.

2. Passing threshold of joint loss

- In the event list, when the calculated event point connection loss is greater than the set connection loss passing threshold, the connection loss value will be marked with “*”.

3. Reflection loss passing threshold

- In the event list, when the calculated reflection loss at the event point is greater than the set reflection loss passing threshold, the reflection loss value will be marked with “*”.

4. Fiber terminal threshold

- When the connection loss of the event point is greater than the threshold value of the fiber terminal, the event point is considered as the fiber terminal. All events after this event point are ignored and not shown in the list.

The fiber length measured is inaccurate	a. Refractive index of Optical fiber is not set correctly.	a. Set the refractive index of the fiber to the index specified by the fiber manufacturer.
	b. Cable correction factor is not set.	b. Set the cable correction factor to 1.0000 or the cable correction factor specified by cable manufacturer.
The average loss of fiber measured is not accurate	a. The fiber length error measured is too large	a. Refer to the previous item to measure the fiber length accurately.
	b. The front tail of the test curve is too long	b. After cleaning the connector of the fiber under test or adding a little matching fluid, retest the curve.
There is no test waveform on the screen, only the front reflection peak, or the front reflection peak has a long tail.	The end face of the connector is dirty.	Wipe the end face of the fiber clean with 99% isopropyl or fiber cleaning fluid.
	The end face of the device is dirty.	Remove the connected fiber and clean the fiber end face and device end face using 99$ isopropyl alcohol or fiber cleaning fluid.
	The ceramic core of the connector is cracked or broken	Replace the fiber connector with a new one.
	Fiber connector type mismatch	The end face type of the fiber connector being tested must match the end face type in the OTDR optical output connector. If these are mismatched, you will not get accurate results.

REASONS FOR FAILURE OF CURVE TEST & ANALYSIS

If the results are quite different from the expected result (or the expected result does not appear), it may be caused by one of the following reasons:

1. The test curve of the fiber was not obtained.

If the test curve only has the front-end reflection peak, and there is no linear curve reflecting the characteristics of the fiber, please check:

1. Whether the end-face type of the tested fiber is the same as the end-face type of the OTDR optical output port (APC).
2. Whether the end-face of the fiber is contaminated with dirt, grime, or dust.
3. Whether the optical output ferrule of the OTDR is cracked or damaged.

If the fiber link tested is very short (<100 m), the following test methods and conditions are recommended:

Settings

Test Mode: Average

Measuring Range: <800 m

Pulse Width: <80ns

Attenuation: 15dB or 20dB

Average Time: Depends on Attenuation Setting

NOTE: If 15dB attenuation is set, a better SNR test curve can be obtained, which improves the curve analysis. A smaller test blind area can be obtained by setting the attenuation to 20 dB, but the signal-to-noise ratio of the curve is relatively low, so a larger average time is needed to obtain a curve with a higher signal-to-noise ratio.

1. If a relatively serious trailing phenomenon is observed on the falling edge of the reflection peak at the near end of the test curve, please try the following:

2. Dip a cotton wool ball in an appropriate amount of 99% isopropyl, or another fiber cleaning fluid, to clean the end-face of the tested fiber and the optical output ferrule of the OTDR.

3. Re-test the curve with a smaller pulse width. (note that the average test mode is selected and the average time is set).

4. Re-test the curve with a large attenuation at the current pulse width (note that the average test mode is selected and the average time is set).

5. If the event points in the test curve are too close together, or if an adjacent event point is found missing, please try the following:

6. Re-test the curve with a smaller pulse width (note that the average test is selected and the average time is set).

7. Please set a certain average time and use the average test method to improve the signal-to-noise ratio of the curve.

8. If the SNR (Signal-to-Noise Ratio) of the test curve is poor, the accuracy of the curve analysis will be affected. In this case, try the following:

9. In the automatic test or average test mode, increase the average time value appropriately.

10. Use a larger pulse width to retest after adjusting the settings to the appropriate test range under the average test mode.

11. If there is a big difference between the measured fiber length and the actual value, please check:

12. Whether the refractive index value and optical fiber correction coefficient value set are consistent with the nominal value of the fiber or optical fiber measured.

13. If the refractive index is not consistent, the measured length of the fiber will be affected.

EVENT POINT TYPES

The event points created by the OTDR are either reflective event points and non-reflective event points.

Reflective event points are usually caused by a fixed connector or a fractured surface at the end of the optical fiber, representing a peak. See example below for reference:

Non-reflective events typically include:

• Descending event point
- Ascending event point
• Non-reflective end of optical fiber

APPENDIX

Because the fiber core is very small, dust and other particles may get stuck to the optical output ports, which may cover part of the fiber core, leading to the subpar performance of the device. Dust and particles may also cause the end face of the output port ferrules to wear, which will reduce the accuracy and repeatability of the device. Cleaning the device periodically, as described below, will prevent those issues.

1. The optical output ports must be kept clean, and the optical output ports should be cleaned regularly with anhydrous ethanol, 99% isopropyl alcohol, or fiber cleaning fluid.
2. After the device is used, please cover the dust cap and keep it clean.
3. The ferrule of the light source output port must be cleaned periodically. If the ceramic core in the ferrule is found to be cracked, replace the ferrule as soon as possible.

While cleaning, follow the below safety principles:

1. Be sure to turn off the power supply when cleaning.
2. Failure to follow the prescribed control, regulation, or operating procedures may result in dangerous radiation damage.
3. When cleaning any optical interface, make sure the optical source is disabled.
4. Do not look directly at any optical output port while the instrument is on to avoid eye damage.
5. Please use optical fiber cleaners, optical fiber cleaning rods, or other similar tools to clean the optical output interface and connectors.

Steps to clean the optical output interface and connector:

1. Ensure the power to the device is turned off.
2. Unscrew the ferrule cap completely.
3. Gently pull out the ferrule.
4. Clean the end face of the optical output connector and the flange connector with a cotton wool ball dipped in an appropriate amount of anhydrous ethanol or fiber cleaning fluid.
5. After cleaning, gently connect the ferrule to the optical output port, and then tighten the ferrule.
