What is an integrated wiring system? Several basic problems of an integrated wiring system? Integrated wiring is a modular, highly flexible information transmission channel within or between buildings. It can connect voice equipment, data equipment, switching equipment and various control equipment with the information management system through it, and at the same time connect these equipment with the integrated wiring of the external communication network. It also includes all cables and related connecting parts between the connection point of the building's external network or telecommunication line and the application system equipment. Integrated wiring consists 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 construct various sub-systems. They have their own specific purposes, which are not only easy to implement, but also can be smoothly upgraded with changes in demand. 1. What is an integrated wiring system. The so-called integrated wiring system refers to the compilation and arrangement of communication lines of various systems in various buildings (or building groups) in a standard, unified and simple structured manner, including network systems and telephones. System, monitoring system, power supply system and lighting system, etc. Therefore, the integrated wiring system is a standard and universal information transmission system. 2. Several basic problems of the integrated wiring system 1) Bandwidth and transmission rate When it comes to choosing an integrated wiring system, there are two concepts to be distinguished first, that is, bandwidth (measured in MHZ) and data transmission rate (measured in Mbit/S). To measure). It is difficult to make the right choice if you do not distinguish between these two concepts. For the definition and specific meaning of the two, please refer to related technical articles. What I want to point out here is the relationship between the two. This relationship is related to encoding methods and other technologies, but it is not necessarily a one-to-one relationship. For example, ATM155, where 155 refers to the data transmission rate, that is, 155Mbit/S, and the actual bandwidth is only 80MHZ; another example is 1000Mbit/S gigabit Ethernet, due to the 4-pair full-duplex working mode, its transmission The bandwidth requirement is only 100MHZ. In computer network operations, the data transmission rate is widely used, while in the cable industry, bandwidth is used, so don't confuse the two. 2) New type of cable system ① Enhanced Cat 5 cable system (Enhanced Cat 5): a new type of cable system produced by improving part of the existing category 5 UPT twisted-pair cable. Many performance parameters, such as near-end crosstalk (NEXT), attenuation crosstalk ratio (ACR), etc. have been improved, but its transmission bandwidth is still 100MHz. ② Category 6 cable system (Cat 6): A new level of cable system, in addition to greatly improved performance parameters, its bandwidth will be expanded to 200MHZ or higher. ③Category 7 cable system: Category 7 cable system is a cable standard proposed by Europe. Its planned bandwidth is 600MHZ, but the structure of its connection module is completely incompatible with the current RJ-45. It is a shielding system.
