NF-919 3-in-1 Fiber Optic Power Meter, Light Source & VFL
The NF-919 is a professional, easy-to-use fiber optic tester designed for installation, maintenance, and troubleshooting of fiber optic networks. It integrates three essential functions: Optical Power Meter (OPM), Stable Light Source (SL), and Visual Fault Locator (VFL) with a 650nm red laser. Whether you're testing fiber loss, identifying wavelengths, or locating breaks, the NF-919 delivers reliable performance in a compact, portable design.
Key Features:
- Optical Power Meter (OPM)
- Supports 10 standard wavelengths (8501650nm). Measures absolute power (dBm/mW/uW/nW) and relative power (dB). Ideal for rapid power and loss detection.
- Stable Light Source (SL)
- Provides 1310nm and 1550nm wavelengths with adjustable frequencies (270Hz, 1000Hz, 2000Hz). Helps evaluate fiber transmission quality and link loss.
- Visual Fault Locator (VFL)
- Built-in 650nm red laser with steady on/flashing mode. Easily penetrates long-distance fibers to locate bends, breaks, or faulty connectors.
- User-Friendly Interface
- Clear LCD display with intuitive icons. Short press to switch modes, wavelengths, or units. Long press to set reference values or calibrate.
- Reference & Calibration Function
- One-key REF setting to store reference power values. Supports user calibration and factory reset for long-term accuracy.
