Main Advantages
10-in-1 Multifunction Design
The NF-859GT combines multiple diagnostic tools into a single device, reducing equipment costs and simplifying installation and maintenance workflows.
Upgraded Receiver Unit
The enhanced receiver supports wire mapping, cable tracing, PoE testing, VFL operation, crimp testing, and flashlight functionality, reducing the need to move between cable endpoints during testing.
Wide Cable Compatibility
Supports RJ11, RJ45, CAT5, CAT5e, CAT6, CAT6A, telephone cables, and fiber optic cables, making it suitable for a wide range of networking applications.
Accurate Cable Length Testing
Measures cable length from 5 to 200 meters, helping technicians locate faults and verify installations quickly and accurately.
Advanced PoE Analysis
Identifies PoE voltage, power pairs, End-span and Mid-span configurations, and supports IEEE 802.3af/at standards as well as non-standard PoE devices.
Optical Power Meter (OPM)
Supports optical power testing at 850, 1300, 1310, 1490, 1550, and 1625 nm wavelengths, making it suitable for fiber optic installation and maintenance tasks.
10mW Visual Fault Locator (VFL)
The built-in red laser source helps quickly identify fiber breaks, bends, and other faults. Continuous, slow flash, and fast flash modes are supported.
Anti-Interference Cable Tracing
Digital anti-interference mode improves tracing accuracy in electrically noisy environments and on active network cables.
