Noyafa Network Cable Tester with LCD, PoE, Cable Length, Port Flashing, Tone Tracing & Visual Fault Locator NF-858C

The Noyafa NF-858C Network Cable Tester is an advanced, all-in-one diagnostic instrument engineered for network engineers, telecommunications installers, and IT technicians. Designed to streamline structured cabling installation and troubleshooting, this versatile tool tests RJ45 Ethernet, RJ11 telephone, BNC coaxial, and fiber optic cables with superior precision.

Key Features

• Multi-Cable Diagnostic Capability: Thoroughly checks and diagnoses continuity, open circuits, short circuits, and crossed wires across RJ45 (Cat5/5e/6/6a), RJ11, and BNC coaxial cabling.
• Anti-Interference Tone Tracing: Effortlessly track, trace, and locate communication wiring and cables without background noise or AC electrical interference.
• Visual Fault Locator (VFL): Built-in optical fiber tester quickly detects breaks, bends, and faults in fiber optic lines.
• PoE Detection & Voltage Measurement: Identifies which pins are carrying power and measures the exact voltage delivered on active Power over Ethernet connections.
• Hub Blink / Port Flashing: Easily locate connected network ports on busy switches, routers, and hubs via synchronized port light blinking.
• Precise Cable Length Measurement: Accurately measures the length of LAN and coaxial cables and pinpoints fault locations without requiring a remote unit.
• Telephone Line Polarity & Status Check: Instantly determine line condition (Tip or Ring) and electrical polarity (anode or cathode).
• Clear LCD Interface: Features an easy-to-read backlit digital screen for fast, real-time diagnostic readings in any work environment.
