The Noyafa NF-8508 Tester is an advanced multifunction optical fiber and LAN cable tester that combines essential network diagnostics into a single portable device for field technicians, network installers, and maintenance professionals. Designed for both fiber optic and Ethernet (RJ45/RJ11) networks, the Noyafa NF-8508 Tester performs a wide range of tests including wire mapping, cable scanning, port flashing, and accurate cable length measurement up to 200 m, making it ideal for structured cabling and telecom installations. It also includes a PoE test that detects standard and non-standard PoE devices, checking voltage, polarity, and power delivery to ensure proper network power configuration. For fiber optic maintenance, the NF-8508 features optical power meter (OPM) capability and a visual fault locator (VFL) with a 10 mW laser to find breaks and bends in fiber cables. Additionally, this tester offers NCV (non-contact voltage) detection and continuity checks to improve safety and troubleshooting efficiency during on-site diagnosis. With a durable Type-C rechargeable 1500 mAh lithium battery and clear LCD interface, the Noyafa NF-8508 Tester delivers reliable performance for LAN and fiber testing in offices, data centers, and field environments.
