Introduction to Cabling Standards for integrated cabling systems

The Integrated Wiring System is not traceable so far. ISO/IEC11801 is available internationally; ANSI/EIA/TIA568A is available in North America; EN50173 is available in Europe; EIA/TIA 569 is available for construction and installation; the test has an unshielded twisted pair laying System field test transfer performance specification ANSI/TIA/EIA PN3287, that is, TSB67. Our country has China Engineering Construction Standardization Association standard "Architectural and architectural complex integrated wiring system engineering design specifications" CECS72: 97 and "Building and architectural complex Integrated Wiring System Engineering Construction and acceptance specifications" CECS89: 97 available for use; Shandong Province has the "test and acceptance of Integrated Wiring System" Shandong Province local standards as the basis for Party A's acceptance and testing.

In fact, the pioneer in the field of cabling system standards is the EIA/TIA association. In 1985, EIA/TIA began the formulation of Cabling Standards. After six years of efforts, the first version of EIA/TIA 1991 was formed in 568, this is the foundation document of Integrated Wiring standards. And EIA/TIA-569, TSB67, TSB40 and other documents form the North America Integrated Wiring series file. TSB36 is a technical system manual for horizontal cabling cables, and TSB40 is a technical system manual for wall sockets. It mainly involves the measurement methods and allowable values that must be observed in terms of loss, crosstalk, and reflection. The EIA/TIA 568 standard was revised to the EIA/TIA 568A standard in October 1995.

The international ISO/IEC 11801 Information Technology-General Cable Laying requirements of the customer was officially promulgated on April 9, August 16, 1995. The EN50173 standard promulgated by CENELEC in Europe was completed on the basis of ISO11801 and has been approved by the European Community and will be implemented in May July 1995.

EIA/TIA 569:
This standard is the product of the joint efforts of the Canadian Standards Association CSA and the American Electronics Industry Association. As the standards greatly affect the equipment selection and construction requirements of commercial buildings, the preparation of standards is very important.
The content includes preface, scope, definition, horizontal wiring, vertical wiring, workstation, communication room, equipment room, lead, equipment grounding and shielding grounding, channels and spaces for isolating fire control and electromagnetic interference sources.
