NF-8508 Network Cable Tester with Optical Power Meter, CAT5 CAT6 Cable Toner Ethernet Cable Tester, RJ45 Network Tester, VFL PoE QC Test Wire Tracer Port Flashing 200M Length Test

High Efficiency Visual Fault Locator: Easy identification of fiber breakpoints, poor connections, bending or cracking. Excellent for finding the right fiber to splice or quickly finding a break.
Emmiting Energy: standard
wavelenth: 650nm. Fast flashing, slow flashing, high precison. The built-in self-calibration ensures stable long-term performance, and Class IIIa laser (output <5mW) ensures safe daily operation.
PORT FLASHING: The indicator light on the connection port in the NF-8508 device flashes to help accurately locate the cable. Displays port information, including operating speed, duplex mode, and negotiation settings. Port lights flash on the same screen to show the port's operating speed, making it easy to pinpoint lines and ports.
PoE Testing and Cable Length Test: PoE testing can check cable mapping polarity and voltage of PoE network switches, withstand 60VDC. Automatically detects and switches between 10M/100M/1000M modes, Includes cable tracking, short circuit test, interruption of circuit test and etc The RJ45 cable tester can quickly measure the length of the cable with a range of 200m. Not only network cables, but also phone lines and BNC cables.
Long Battery Life and Non-Contact VoltageRJ45 network cable tester allows you to set the backlight timeout and automatic shutdown time. It has a built-in 1500mAh 3.7V lithium battery, providing up to 10 hours of battery life, and supports Type-C charging for added convenience. this tester also features non-contact voltage testing, allowing for non-contact voltage testing of household wiring. It is an essential tool for cable tracing, line location, and fault detection.
