An Ethernet panel, often referred to as a wall plate, is a fixture that allows Ethernet cables to connect to a network through a wall. A single white Ethernet panel typically has one port for an Ethernet cable and is designed to blend in with the wall for a clean and professional look. They are compatible with various Ethernet cable categories, such as Cat5, Cat5e, and sometimes Cat6, providing a convenient in-wall connection for internet access and network linking.
