A patch panel is a hardware device that provides a central point of control for multiple connections, allowing cables from different sources to be organized and terminated in an organized way. It is generally used in computer networking, telecommunications, and audio/video applications. In a typical networking setup, patch panel is used to create connection between incoming and outgoing data cables with routers, switches, and other network devices. This helps to streamline cable management and makes it easy to switch connections and troubleshoot problems. Patch panel has several ports on the front, where cables are connected and a corresponding number of ports on the back that are wired to a larger network infrastructure.
