6. Instruccions de funcionament
The Komshine QX70 offers multiple testing modes. Navigate through the touch screen interface to select the desired function.
6.1 OTDR Measurement
- From the main menu, select the "OTDR" function.
- Configure measurement parameters such as wavelength (1310/1550/1625nm), pulse width, distance range, and measurement mode (e.g., Auto, Manual).
- Connect the fiber under test to the OTDR port.
- Press the "Start" or "Measure" button to begin the test.
- The OTDR trace will be displayed on the screen, showing events like splices, connectors, and fiber ends. The iOLM link map function provides a simplified graphical representation.
- Analyze the results using the on-screen tools. Save the trace data for later analysis using the included software.
6.2 Funció del mesurador de potència òptica (OPM)
- Select the "OPM" function from the main menu.
- Choose the desired wavelength (850/1300/1310/1490/1550/1625nm).
- Connect the fiber carrying the optical signal to the OPM port.
- The optical power level will be displayed in dBm or mW.
6.3 Funció del localitzador visual de fallades (VFL)
