5. Kullanım Talimatları
5.1 Basic OTDR Measurement
- Fiber bağlantısı: Connect the fiber optic cable to be tested to the OTDR port using the appropriate adapter. If using a launch cable, connect it between the OTDR and the fiber under test.
- Access OTDR Function: From the main menu, select the OTDR function.
- Parametreleri Ayarlayın: Configure measurement parameters such as wavelength (1310nm or 1550nm), pulse width, and distance range using the touch screen or keypad. The device offers pulse widths from 10ns to 20480ns and distance ranges up to 256km.
- Ölçümü Başlat: Press the 'Start' or 'Measure' button to initiate the fiber scan. The OTDR will display the trace on the TFT-LCD screen.
- Sonuçları Analiz Et: The GUI interface provides a clear visual representation of the fiber trace, showing events like splices, connectors, and fiber ends. Key metrics such as total loss, length, and attenuation will be displayed.
- Veri kaydet: Save the measurement results to the SD card for later analysis using the included Curve Analyze Software.
5.2 Using the Visual Fault Locator (VFL)
The QX45 model includes a built-in VFL for quick visual inspection of fiber integrity.
- Fiber bağlantısı: Connect the fiber to be inspected to the VFL port.
- Activate VFL: From the main menu or dedicated button, activate the VFL function. A red laser light will be emitted into the fiber.
- Inspect Fiber: Observe the fiber for any visible light leakage, which indicates breaks, macro-bends, or faulty connectors.
6. Bakım
6.1 Cleaning the OTDR Ports
Regular cleaning of the optical ports is crucial for accurate measurements and to prevent damage to the device and fiber connectors.
- Temizlemeden önce cihazı mutlaka kapatın.
- Use the provided clean swabs or other approved fiber optic cleaning tools.
- Gently clean the ferrule and adapter sleeves of the OTDR ports.

9. Kullanıcı İpuçları
- Always use a launch cable (also known as a pulse suppressor box or fiber ring) when testing short fiber runs or the first connector of a fiber link. This helps to absorb the OTDR's dead zone and allows for accurate measurement of the first connector.
- Ensure all fiber end-faces are meticulously clean before connecting them to the OTDR or other fiber components. Contamination is a leading cause of inaccurate measurements and potential damage.
- Familiarize yourself with the different pulse width settings. Shorter pulse widths offer better resolution for identifying closely spaced events, while longer pulse widths provide a greater dynamic range for testing longer fiber links.
- Utilize the included Curve Analyze Software on your PC to perform in-depth analysis of saved traces, generate reports, and manage your measurement data efficiently.
