NOYAFA NF-8508 Network Cable Tester with Optical Power Meter

• Multifunctional NOYAFA NF-8508 Network Cable Tester: There are nine features to meet your needs. Continuity Testing, Cable Scan, Port Flash, Length Measurement, POE Power Supply Test, QC testing, Optical Power Meter, VFL and NVC function.It is perfectly suited for various engineering cabling projects, network troubleshooting, network equipment maintenance and testing scenarios. Its precise cable scanning and fault localization capabilities help you effortlessly pinpoint the root cause of issues.
• 7 WAVELENGTHS OPTICAL POWER METER: NF-8508 network cable tester can measure 7 standard wavelengths, 850/1300/1310/1490/1550/1625/1650, power detecting range(dBm): -70 ~ +10. Its power detection range spans from -70 dBm to +10 dBm, supporting FC/SC/ST connectors. It enables precise fiber optic power measurement, helping users efficiently assess fiber signal strength and ensure healthy fiber link operation. It effortlessly detects attenuation issues within fibers, thereby safeguarding fiber network stability.
• 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 (output5mW) 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 Voltage】RJ45 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.
