Noyafa Multi-Function Cable Tester with RJ11/RJ45, PoE, Fiber Optic OPM/VFL, NCV & Cable Length Measurement NF-8508

The Noyafa NF-8508 Multi-Function Cable Tester is an advanced, all-in-one diagnostic instrument engineered for network engineers, telecom professionals, and structured cabling installers. Combining comprehensive twisted-pair network testing with precision optical fiber diagnostics, the NF-8508 eliminates the need to carry multiple handheld meters on the job site.

Comprehensive Cable & Wire Analysis

Effortlessly verify Cat5, Cat5e, and Cat6 network cables with detailed wire mapping and continuity testing. The clear LCD screen pinpoints common wiring faults, including opens, shorts, crossed pairs, and split pairs. With built-in TDR-based length testing, you can accurately measure cable runs up to 200 meters (656 feet) to streamline preparation and verify link distances before commissioning.

Advanced Network Diagnostics & PoE Testing

Diagnose active network drops instantly. The PoE testing module identifies standard IEEE 802.3af/at Power over Ethernet protocols, verifying voltage levels, polarity, and power-delivering pinouts. Additionally, the port flash function syncs directly with network hubs, switches, and patch panels to quickly locate specific switch ports amidst dense cabling setups.

Integrated Fiber Optics & Safety Tools

Beyond copper ethernet, the NF-8508 features an integrated Optical Power Meter (OPM) for measuring optical power and link loss across multiple wavelengths, paired with a high-visibility Visual Fault Locator (VFL) to locate fiber breaks and sharp bends. For added technician safety, the receiver unit incorporates a Non-Contact Voltage (NCV) sensor to alert users to live AC wiring before handling cables.
