Noyafa NF-981 - multifunction OTDR tester
Functions: OTDR/EVENT MAP/OPM/LS/VFL/RJ45 Sequence/RJ45 Line length/Flashlight
> OTDR (Optical Time Domain Reflectometer) - Single-mode OTDR with a dynamic range of 22/20 decibels (dB), capable of testing over a range of 80 kilometers, equipped with SC/PC or FC/PC optical interfaces.
> Optical link intelligent analysis - OTDR software offers comprehensive test reports including Reflective Event, Reduce Event, Fiber Splitter, and Fiber End analyses.
> OPM (Optical Power Meter) - Measures optical power within a range of -50 to +26 decibel milliwatts (dBm) with six wavelength calibration capabilities.
> VFL (Visual Fault Locator) - Emits red light with an output power of 10 milliwatts (mW).
> Wire Mapping - Identifies faults such as short circuits, open circuits, and cross-connections in LAN cables.
> Length Test - Measures cable lengths ranging from 1 to 600 meters.
> Lamp - Provides a reliable light source for illumination in dim working environments.
