NOYAFA NF-802 Cable tester

A multifunction cable tester that combines cable tracing, wire mapping, port flashing, crimping test, and telephone line analysis (polarity, ringing, line status). With digital technology, it enables accurate cable identification even in noisy environments. The built-in NCV detection alerts you to live wires. The device features an LED flashlight, a rechargeable 1400mAh battery with USB-C charging, and is ideal for network technicians during installation or maintenance of Ethernet and telephone networks. Key Features • Wire mapping – detects correct pair order, shorts, opens, or cross connections • Crimping QC test – verifies which end of the cable is not properly terminated • Cable detection and tracing (Cable Tracing / Port Flash) – locates the cable via tone signal or port blinking on a switch/router • NCV non-contact voltage detection – quickly identifies the presence of live current, enhancing workplace safety • LED lighting – helps in low-light or dark environments
