In the choice of network cabling, we often have some entanglements. As two typical schemes of wiring, point-to-point network cabling and structured cabling have their own advantages and disadvantages. How do we choose? What is structured wiring? Point-to-point network cabling refers to the direct connection between the switch to the server, the server to the storage, the server to other servers, etc. Although this wiring has low latency, it is only in the data center due to its high cost and maintenance cost. Some special field applications. Nowadays, as data centers continue to move toward high density, high speed and scale, structured cabling is becoming the mainstream of data center cabling. This article covers the basics of structured cabling. The structured cabling system is a telecommunications cabling system that supports any user-selected voice, data, and graphics applications. The system should be able to support the transmission of various information such as voice, graphics, images, data multimedia, security monitoring, and sensing. It consists mainly of six subsystems in the following table: Organizations such as the American National Standards Institute (ANSI), the Electronic Industries Alliance (EIA), the Telecommunications Industry Association (TIA), the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and the European Committee for Electrotechnical Standardization (CENELEC) are involved in the development of structures. Standards for wiring, which determine the performance and technical standards of the various components of a variety of cabling systems, helping to build a structure that is sexual, open, flexible, reliable, advanced, and economical. Wiring system. The transmission mediums of the vertical trunk subsystem and the horizontal subsystem in the structured cabling system are both optical cable and copper cable. The two transmission media are described in detail below. As an emerging transmission medium, optical cable is widely welcomed by the vertical trunk subsystem cabling because of its high bandwidth and long transmission distance. Moreover, cable routing has higher network flexibility than copper cabling of similar construction. Copper cables are typically used for horizontal subsystem and work area subsystem cabling. In addition, since the ports of the copper connectors can also be connected to switches and other devices, they can also be used for inter-device subsystem cabling. Copper cables are rarely used in vertical trunk subsystem cabling because their transmission distance is only 100 m, while the distance between devices in a vertical trunk subsystem is typically greater than 100 m. Having said so much about the basics of structured cabling, you might want to ask: Is structured cabling really suitable for all applications? In fact, the choice of wiring should be determined by the specific situation and the final desired effect. Both structured cabling and point-to-point wiring are widely used in Ethernet cabling, both of which have advantages and disadvantages. In short, point-to-point wiring is suitable for data centers with fewer devices and simpler network environments. Structured cabling is open and flexible. No matter how the devices of each subsystem change and how the position moves, we only need to change the wiring system. The position of the jumper does not require any other changes; it can fully adapt to the development of communication and computer networks, and lays a solid line foundation for the overall automation of the office in the future. This paper mainly introduces the basic knowledge of structured wiring, and compares the advantages and disadvantages of structured wiring and point-to-point wiring, which has a certain reference for users to choose structured wiring or point-to-point wiring. If you choose to use structured cabling, choosing the right, cost-effective structured cabling product is critical to building a reliable, high-performance, structured cabling system.
