- Carefully insert the fiber optic cable into the adapter. Avoid excessive force.
6. 사용 설명서
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).
- 테스트 대상 광섬유를 OTDR 포트에 연결하십시오.
- 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 Optical Power Meter (OPM) Function
- 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 Visual Fault Locator (VFL) Function
- Select the "VFL" function from the main menu.
- Connect the fiber to the VFL port.
- Activate the VFL. A visible red laser light will be emitted into the fiber.
- Inspect the fiber along its path for light leakage, which indicates breaks, tight bends, or faulty connectors.
