MULTI-FUNCTION NETWORK CABLE TESTER 9 FUNCTIONS: NOYAFA NF-8508 network cable tester is an ideal tool for network engineers, IT professionals and equipment maintenance personnel. Cable continuity test, cable scanning, port flicker, length measurement, POE power test, optical power meter, NVC function and other powerful features, perfectly adapted to various types of engineering cabling, network troubleshooting, equipment testing and other work scenarios is the maintenance and testing of network equipment.Accurate cable scanning and fault locator QC TEST AND AUTOMATIC SCANNING TO IDENTIFY THE CONTINUITY TEST: Ethernet cable tester QC function can help users to test the RJ11/RJ45 network cable Plug is connected correctly. The function supports Automatic scanning identification of any type of network cable, such as Cat5, Cat5e, Cat6, Cat6a (including UTP/STP), even if only one end is connected, the tester can accurately identify and confirm the connection status of the cable, to ensure that the network is connected correctly, in the case of network wiring, cable installation or equipment testing, etc., to reduce network failures caused by cable problems POE TEST PORT FLASHING TO ENSURE STABLE OPERATION OF EQUIPMENT: LAN tester is equipped with POE power test function, which can accurately detect the power polarity, voltage and power supply status of POE network switches. It can automatically switch to support 10M/100M/1000M modes to ensure the stability of the power supply of the device, supporting a maximum of 60VDC voltage. Applicable to POE switches (standard and non-standard) port blinking function can quickly identify the port operating speed, and display the working status of the port to help quickly locate the problem OPTICAL FIBRE RATE METER SUPPORT MULTI-WAVELENGTH ACCURATE CABLE FAULT LOCATION: network tester equipped with optical power meter can detect different wavelengths of optical signals (including 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm). With a power detection range of -70 dBm to +10 dBm, it supports FC/SC/ST interfaces and accurately measures the power of optical fibres, helping users to efficiently measure the signal strength of optical fibres and ensure the healthy operation of optical fibre links. It can easily detect attenuation problems in the optical fibre to ensure the stability of the optical fibre network Efficient and rapid detection of fiber breaks and poor contact: NF-8508 effectively identifies fiber breaks, poor contact, bends, or cracks. With its high output power and 650nm wavelength, it allows you to quickly locate fiber faults, improving troubleshooting efficiency. This feature is ideal for fiber engineers and maintenance personnel during installation and commissioning, especially in data centers, telecommunications companies, smart buildings, fiber troubleshooting, and fiber network monitoring environments, ensuring stable fiber link operation and preventing network disruptions. PORT FLASHING AND CABLE LOCATION ACCURATE IDENTIFICATION OF PORT INFORMATION ：The Port flash function helps users locate network cables and ports by flashing the indicator light, and displays important information such as port operating speed, duplex mode, negotiation settings, etc. Through this function, you can quickly identify ports. With this function, you can quickly identify the status and problems of network devices, reduce troubleshooting time and improve work efficiency. In enterprise network maintenance, IT management and network equipment debugging, it helps technicians quickly diagnose port problems and ensure network stability CABLE LENGTH MEASUREMENT: USB C CHARGING FOR LONG TIME WORK：Internet test tools to support long time work, equipped with LED flashlight can solve the low light environment in the dark working environment, for indoor and outdoor testing, dark light environment, RJ45 tester is especially suitable for outdoor network maintenance, power installation and site testing, so that you can work efficiently in any environment, the cable measurement length: 2.5m-200m, accuracy: ± 1.6m, can be used as a holiday!
