Jonard Tools Mini Optical Power Meter is designed to measure the absolute optical power and relative power loss in fiber optic cables. The power meter features a built-in 2mW visual fault locator (VFL) and network cable tester/remote. The VFL identifies faults in fiber cables in a pinch. The Jonard Tools Mini Optical Power Meter measures 10 preset calibrated wavelengths from 800nm to 1650nm with a 0.01dB resolution. The power meter provides a backlit LED screen for easy viewing in low-light environments. The Mini Optical power meter comes with FC and LC adapters, so the fiber APC/PC/UPC connectors can be directly connected to the tool. The power meter operates for up to 120 hours.
