5.2 Powering On/Off

• To Power On: Press and hold the power button (usually located on the side or front panel) until the screen illuminates.
• To Power Off: Press and hold the power button until a shutdown prompt appears, then confirm. Alternatively, a quick press might bring up a power menu.

5.3 Connecting Fiber Optic Cables

The QX70 comes with FC, SC, and LC UPC adapters. Select the appropriate adapter for your fiber connector type.

1. Ensure the fiber end-face and the OTDR's optical port are clean. Use a fiber optic cleaner if necessary.
2. Attach the correct adapter to the OTDR's optical port.
3. Carefully insert the fiber optic cable into the adapter. Avoid excessive force.

6. Operating Instructions

The Komshine QX70 offers multiple testing modes. Navigate through the touch screen interface to select the desired function.

6.1 OTDR Measurement

1. From the main menu, select the "OTDR" function.
2. Configure measurement parameters such as wavelength (1310/1550/1625nm), pulse width, distance range, and measurement mode (e.g., Auto, Manual).
3. Connect the fiber under test to the OTDR port.
4. Press the "Start" or "Measure" button to begin the test.
5. 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.
6. 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

1. Select the "OPM" function from the main menu.
2. Choose the desired wavelength (850/1300/1310/1490/1550/1625nm).
3. Connect the fiber carrying the optical signal to the OPM port.
4. The optical power level will be displayed in dBm or mW.

6.3 Visual Fault Locator (VFL) Function

1. Select the "VFL" function from the main menu.
2. Connect the fiber to the VFL port.
3. Activate the VFL. A visible red laser light will be emitted into the fiber.
4. Inspect the fiber along its path for light leakage, which indicates breaks, tight bends, or faulty connectors.
