With the increase in computer desktop processing capabilities and the increasing demand for networking among users, a new generation of local area network (LAN) technology has been formed. In order to meet the needs of data transmission rate increase, 100 ohm unshielded symmetric twisted pair and optical fiber are ideal choices for cabling.
When designing a network system, cabling is a key factor. With the rapid development of the Internet and the increase in the use of computer desktops, the market for wiring new technologies connected to desktops has broad prospects and provides unlimited business opportunities for Category 5E and Category 6 cabling.
Integrated wiring technology
1. Cabling Standards The LAN technology described in this document refers to the TIA/EIA-568-A (Commercial Building Telecommunications Cabling Standard) and ISO/IEC 11801:1995(E) standards. The content of the wiring standard includes the wiring network topology, performance, components, installation practices and field tests. There are many telecom standards related to it, such as ATMForum, CC99vT, CENELEC, IEEEANSI802, and so on.
2. The cabling topology TIA/EIA-568-A and the ISO/IEC 11801 cabling standard are based on the same basic cabling system structure, and its system structure has strict and explicit definitions in the standard. The cabling system includes cables, patch cords, and connectors for horizontal cabling, in-building backbone cabling, and architectural backbone cabling. Structured cabling supports cabling termination while using patch cords that are easily connected to devices or cross-connected.
3. Wiring distance In the standard, there are strict wiring distances (horizontal wiring <90 meters, building trunk <500 meters, campus trunk <1500 meters), and the wiring distance depends on the actual work area (ie, the building floor area). The trunk wiring distance is based on the distance defined by the actual application.
4. Cabling performance In the TIA/EIA-568-A and ISO/IEC11801 standards, 100-ohm twisted-pair cables are classified according to their performance:
Category 3: Specified as 16 MHz;
Category 4: Specified as 20MHz;
Category 5/5E: Specified as 100MHz;
Category 6: Specified for 250MHz.
5. Cable electrical transmission performance parameters DC resistance unbalanced;
DC Resistance;
