2.1.1 Test Parameter
Wavelength: 1310nm, 1550nm (Optional: 1625nm, 1650nm online test and 850nm\/1300nm multimode)\u00a0
Measuring range:
AUTO mode: The device will automatically set the most appropriate parameters for the current measurement, and the\u00a0
measurement range and pulse width selected values cannot be modified at this time.\u00a0
Manual mode: The range and pulse width can be set manually.\u00a0
Pulse Width: Pulse width refers to the time width of emitting optical pulse signal during measurement. The wider\u00a0
the pulse width is, the stronger the optical power injected into the fibre, the stronger the backscattering signal of the\u00a0
f
ibre, the further the OTDR can effectively detect. The wide pulse width will cause saturation of the\u00a0
initial reflection signal and could result in large blind areas. Please note, the selection of pulse width is related to the\u00a0
measurement of fibre. The longer the length is, the wider the pulse width. It can only be modified in the automatic\u00a0
measurement mode, which defaults to \u2018automatic configuration\u2019
Measuring time: In the mean measurement mode, the longer the detection time is, the better the signal-to-noise\u00a0
ratio, the more accurate the test results are. The user should select the detection time, which is proportional to the\u00a0
dynamic measurement. \u00a0\u00a0
Resolution: High resolution will have more sampling points and higher accuracy, but it will also increase the amount of\u00a0
data collected.\u00a0
Refractive index: Is the essential characteristics of optical fibre, which will differ between fibre optic manufacturers.\u00a0
The refractive index is the key parameter to calculate the distance, which can not be arbitrarily set.
Unit: km\/feet\/miles\u00a0
OTDR will automatically select the most appropriate reference pulse width when manual measurement range is set in\u00a0
automatic mode.\u00a0
The range and pulse width can be adjusted manually in manual mode. The following list is for reference only:<\/p>\n\n\n\n

\"8000MAX<\/figure>\n\n\n\n

2.1.2 OTDR Parameter Setting
Various event measurement thresholds, including attenuation, reflection, slope, optical fibre end refractive index and\u00a0
scattering coefficient settings.\u00a0
The refractive index is selected by the user, and changing the refractive index setting will change the ranging result.\u00a0
The refractive index is provided by the fibre optic cable or fibre optic manufacturer. Users are advised to calibrate the\u00a0
group refractive index with a known length of fibre and record it.\u00a0
The scattering coefficient is usually obtained from the fibre optic cable manufacturer
2.1.3 Restore to Default
Restore to factory default Settings.

REAL TIME MODE:\u00a0
Parameter settings->Test time->Average mode; press [REAL\/AVG] key enter the real-time measurement mode. The\u00a0
current circuit is measured in real time, and the measurement parameters cannot be modified in the measurement\u00a0
mode. If the parameters need to be modified, the test needs to be stopped first. Event analysis will not be conducted\u00a0
during the real-time test, and event analysis will only be conducted after the test is stopped<\/p>\n\n\n\n

AVERAGE MODE\u00a0
Real time mode
Parameter settings\/Test time\/XX seconds; Press [REAL\/AVG] key enter the real-time measurement mode. The curve\u00a0
consisting of the average values measured over a period of time can be displayed. The length of time can be edited\u00a0
in the \u2018measurement time\u2019 option in [SETUP].\u00a0<\/p>\n\n\n\n

\"8000MAX<\/figure>\n\n\n\n

When the measurement is finished, the measurement result will be automatically saved.\u00a0
Under no circumstances shall the optical interface and the end of the tail fibre connected to the optical interface be\u00a0
directed to the eye of the operator or other person. Otherwise, the vision of the operator may be damaged, or even\u00a0
blind<\/p>\n\n\n\n

2.3 File Storage
Press [FILE] to view and edit stored files<\/p>\n\n\n\n

The menu provides a complete file storage, call out function. The results of each measurement are automatically\u00a0
saved to internal storage (configurable) and marked with time, date, serial number and other information for easy\u00a0
reference. Users can name, number, comment on each measurement curve, and generate complete reports.\u00a0
2.4 Computer Software
If the user needs to carry out multi-curve comparison or other further analysis functions or remote operation, the\u00a0
measurement data stored in the device after measurement can also be printed by software.
3.0 Other Functional Modules

5.0 Instrument Maintenance and Trouble Shooting
5.1 Cleaning of connectors\u00a0
The optical output interface of this series of fibre optic tester is a universal, replaceable interface. In case the tester\u00a0
fails to test the normal curve, or the test result is not accurate, consider cleaning the connector first.\u00a0
When cleaning, be sure to do it when the OTDR function and visual red light fault location function are turned off.\u00a0
Unscrew the output port and wipe the end face with a special clean paper towel or cotton swab moistened with\u00a0
alcohol. At the same time, please cover the dust cap after the use of the unit, and keep it clean.\u00a0
5.2 Instrument screen cleaning\u00a0
The display of this series of fibre optic comprehensive tester is a 5.6-inch TFT color LCD with touch screen. Do not\u00a0
click the LCD screen with sharp objects when using, otherwise the LCD screen may be damaged: when cleaning, wipe\u00a0
the LCD screen with soft paper. Do not use organic solvent to wipe the LCD screen, otherwise it may cause damage to\u00a0
the LCD screen.\u00a0
5.3 Calibration\u00a0
It is recommended to calibrate the fibre optic tester every two years. For specific calibration, please contact the unit\u00a0
supplier
