(Integrated wiring is a modular, highly flexible information transmission channel within or between buildings. Through it, voice equipment, data equipment, switching equipment and various control equipment can be connected with the information management system, and at the same time, these equipments can be connected with the external communication network. It also includes all cables and related connection components between the connection point of the network or telecommunication line outside the building and the equipment using the system. Integrated wiring is composed of components of different series and specifications, including: transmission media, related connection hardware (such as patch panels, connectors, sockets, plugs, adapters) and electrical protection equipment. These components can be used to build a variety of subsystems, all of which have their own specific purpose, are easy to implement, and can be upgraded smoothly as needs change.)
