A patch panel is a device that contains a number of jacks, usually of the same or similar type, for connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner. Patch panels are commonly used in computer networking, recording studios, and radio and television. They are mounted hardware assemblies that contain ports used to connect and manage incoming and outgoing LAN cables. Patch panels can be mounted within industry-standard 19-inch or 23-inch racks. The patch panel hardware assembly contains blank ports on one side and a termination point on the other. Cables running throughout a building or campus can be terminated, labeled, and then patched into network or audiovisual (AV) hardware. Patch panels are also referred to as patch bays, patch fields, jack panels, or jack fields.

Patch panels are used to facilitate the connection of different devices, such as microphones, electric or electronic instruments, effects, recording gear, amplifiers, or broadcasting equipment. They make it easier to connect different devices in different orders for different projects because all of the changes can be made at the patch panel. Using a patch panel also saves wear and tear on the input jacks of studio gear and instruments because all of the connections are made with the patch panel. Patch panels give flexibility and prevent the need to re-run cables or swap equipment places around if you need to change something or if something breaks. They allow organization, which allows quick troubleshooting. Patch panels are an important piece of equipment in the data center, and using a patch panel comes with many advantages that make it well worth the investment. Some of the most significant benefits of using patch panels include scalability, ease of use, and cost-effectiveness.
