The network cable tester is a versatile tool designed for the testing and troubleshooting of various types of network cables. With support for RJ45 and BNC connectors, it ensures comprehensive testing for both Ethernet and coaxial cables. Additionally, it features testing capabilities for Power over Ethernet (PoE), allowing users to assess the functionality of PoE-enabled networks.

The device enables quick identification of wiring faults such as open circuits, short circuits, and incorrect wiring, contributing to efficient network maintenance and installation processes. Its compatibility with RJ45 and BNC connectors meets the testing requirements of various network environments, including Ethernet and CCTV setups.

The integration of PoE testing functions is particularly valuable in modern network environments where PoE is commonly used to power devices such as IP cameras, access points, and VoIP phones over the same cables that also transmit data. This feature allows users to confirm the availability of power and ensure the proper functioning of PoE-supported devices.
