📋 NOYAFA NF-981 OTDR Fiber Tester and Meter Manual

Features & Benefits:

  • 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.
  • Rechargeable battery – Features a battery standby time exceeding 11 hours, tested for approximately 6 hours of continuous use, with a capacity of 4000 milliampere-hours (mAh), and charges via Micro USB at 5 volts and 2 amperes (A).
