6. Uputstvo za upotrebu
6.1 OTDR Testing
The OTDR function is used to characterize optical fibers, measure length, attenuation, and identify events like splices, connectors, and breaks.
- From the main interface, select "OTDR".
- Connect the fiber to be tested to the appropriate OTDR port. Ensure the connector is clean.
- Adjust test parameters such as wavelength (1625nm for this model), range, and pulse width as needed in the "Setting" menu.
- Press "Start" to begin the test. The device will display the trace curve and event table.
- Use the "Cursor" and "Operate" functions to analyze specific points on the trace.
- Click "Analyze" to automatically detect and list events.

6.2 Event Map Function
The Event Map provides a simplified graphical representation of the fiber link, showing detected events and their locations, making it easier to interpret test results.
- After completing an OTDR test and analyzing the trace, select "Event Map" from the OTDR interface.
- The map will display icons representing different events (e.g., connectors, splices, ends) along the fiber length.
- Click on an event icon for detailed information about that specific event.

6.3 Mjerač optičke snage (OPM)
The OPM measures the optical power of a signal in a fiber optic cable.
- From the main interface, select "Optical Power Meter".
- Connect the fiber to the OPM port.
- The device will display the measured optical power in dBm or mW.
6.4 Optical Light Source (OLS)
The OLS emits a stable optical signal for loss measurement when used in conjunction with an OPM.
- From the main interface, select "Light Source".
- Connect the fiber to the OLS port.
- Select the desired wavelength (1625nm for this model). The OLS will emit a continuous wave.
6.5 Vizualni lokator kvarova (VFL)
The VFL emits a visible red laser light into the fiber, allowing for visual identification of breaks, macrobends, or faulty connectors over short distances (up to 10km).
- From the main interface, select "Visual Fault Locator".
- Connect the fiber to the VFL port.
- Activate the VFL. Observe the fiber for any visible light leakage, which indicates a fault.
6.6 Saving Test Results
Test results can be saved as .sor files for later analysis or reporting.
- After completing an OTDR test, navigate to the "File" option on the OTDR page.
- Select "Save" or "Save as" to store the current trace.
- Unesite a file name using the on-screen keyboard and confirm.
