Power meter with vfl

Combines three vital tools into a single compact device: a precise Optical Power Meter to check signal loss, a bright Visual Fault Locator (red laser) to trace physical cracks or bends in fibers, and an sequential LED step-tester for standard RJ45 network cables.Calibrated Wavelength Support: Measures light power across all standard telecom networks with calibration settings for multiple wavelengths, including 850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm, and 1650nm.
