Features:

• 9-in-1 Cable Testing Multi-functionality: Combines 9 key functions, including wire mapping, digital cable tracing, port flashing, cable length measurement, POE checking, crimping test, OPM (optical power meter), VFL (visual fault location), and NCV (non-contact voltage) test, streamlining network diagnostics in one device.
• Quick Wire Mapping: Quickly check for issues like short circuits, open circuits, or crossed wires in Ethernet cables, simplifying network maintenance and  setup.
• Precision Wire Tracing with Anti-interference: Uses digital signals for reduced noise interference and higher sensitivity, and rapidly detects shielded and un-shielded network cables.
• Fast Port Identification: Locate active network ports and view speed, duplex, and port negotiation settings with synchronized flashing to reduce  troubleshooting time.
• Comprehensive PoE Testing: It can test the information of standard PoE devices, such as PoE voltage, power supply polarity, power supply mode, and also the type of PSE（af or at standard）
• Accurate Cable Length Measurement: Measures cables from 2.5m/8.2ft to 200m/565ft with just a plug-in connection, providing fast and reliable length information for structured cabling.
• Single-End Crimp Testing: Even with one end of an RJ45 cable, the tester provides accurate crimping diagnostics, showing correct and incorrect connections instantly.
• High-Precision Optical Power Testing: Measures optical power and detects light attenuation levels with high accuracy. Equipped with automatic frequency recognition, it allows plug-and-play use for specific wavelengths, ensuring efficiency for tasks involving fiber optic installations.
• Visual Fault Location (VFL): Utilizes a 10mW laser, with fast flash, slow flash, and constant modes for long-distance cable tracing and quick fiber break point navigating.
• NCV (Non-Contact Voltage) Detection: Ensures electrical safety by detecting live wires and electrical equipment, helping you avoid potential electrical hazards.
• Durable Power with Type-C Charging: Long-lasting 1,500mAh polymer lithium battery with Type-C fast charging for extended usage, reducing downtime and increasing efficiency in fieldwork.
• Ensures Reliable, High-Performance Network Cabling: From structured cabling, data cabling, to Fiber Optic cabling installation and maintenance, the      NF-8508 streamlines every stage of the cabling workflow – ensuring networks are built to perform at their highest capacity.
