Features: New Upgraded Multi-function Network Cable Tester: The NF-8506 TDR network tester offers IP scanning, PoE testing, cable tracking, continuity testing, Ping testing, network speed testing, port flashing, sensitivity adjustment, and cable length measurement with a built-in LED flashlight. Cable Length Measurement: This portable tester accurately measures cable lengths from 5 to 200 meters, identifying cable faults and facilitating real-time field measurements. Ping Tester and IP Scanner: This handheld Ping cable tester is ideal for diagnosing and maintaining local area networks (LANs) using TCP/IP protocols. It verifies connections, checks data integrity, measures network traffic load, and provides IP addresses. Network Speed and Cable Continuity Test: Quickly assess network speed issues and conduct Ping tests from multiple locations to evaluate server and website response speeds. Ensure the integrity and connectivity of network cables by detecting breaks, openings, or short circuits. PoE Tester: Efficiently identifies PoE devices and detects crossover methods, including unknown, end-span, mid-span, and 8-core power supply, along with polarity. It offers comprehensive PoE detection, including non-standard schemes and IEEE 802.3AF/AT standards. Port Flashing and Identification: Facilitates quick identification of network cable ports. Indicator lights flash on connected ports, allowing accurate cable localization and displaying port information such as operating rate, duplex mode, and negotiation settings.
