The Integrated Wiring System Project is the basic channel for information transmission in the intelligent community. It performs strict engineering tests and engineering acceptance on the entire transmission channel to ensure the quality of the project, protecting the owners' investment benefits is an extremely important part of the project and an important safeguard measure for inspecting the wiring project. Testing materials are an important part of project acceptance. They play a guiding role in maintenance, maintenance, management, future resizing, and system upgrading.

I. Development and standards of Integrated Wiring

The entire development process of Integrated Wiring in China can go through four stages:

The first stage is the introduction, digestion, absorption, and preliminary engineering application stage, which is embodied in the 1993 ~ May 1995.

The second stage is the stage of extensive application and focus on engineering quality, which is 1995 ~ May 1997.

The third stage is the exploration and innovative application stage, which is 1997 ~ May 2000.

The fourth stage is represented since 2000. Due to the development of communication networks and the emergence of cat5e and cat6 cables, the related standard TIA/EIA-568-B and ISO/iec11801:2000 have successively appeared, and high-speed Ethernet is widely used.

With the increase of intelligent engineering in China, the quality of cabling construction becomes more and more important. With reference to international and domestic standards, the Ministry of Construction issued the "Intelligent Building Engineering Quality Acceptance specification" GB50339-2003 in 2003, as a basis for inspection by the inspection agency, it clearly defines the inspection content and acceptance rules of the Integrated Wiring System. This standard is developed with reference to American standards-ANSI/EIA/TIA-568A and international standards such as TSB67) and is applicable only to five category cabling projects and is not involved in cat5e, cat6, and cat-5e, therefore, Category 5, Category 6, and category 7 should be implemented in accordance with international standards. On the other hand, electrical performance testing methods and accuracy requirements of testing instruments are required for the use of five or more types of Integrated cabling in high-speed broadband scenarios such as Gigabit Ethernet and ATM, should comply with YD/T1013-1999 "Integrated Wiring System Electrical Characteristics of general testing methods". In actual tests, it should be carried out in accordance with national standards and the requirements of international standards and American standards.

International standards mainly include ANSI/EIA/TIA-568B Commercial Building Communication Cable cabling system standards, ANSI/EIA/TIA-568BB.3 optical fiber cabling parts standards, and ISO/IECI1801: 2000 + Information Technology-integrated cabling for user buildings, international standards define Cat 6 and 7 cable standards, and five/D level cabling systems are redefined according to Category 5 +, in order to ensure that the cat5e/D level cabling system can run on Gigabit Ethernet, the comparison methods of laboratory and field tests are also defined, and the on-site testing methods are clarified, for the Cable Testing Method in the Jumper work area, refer to the testing process and the accuracy requirements of the corresponding testing instrument.

The current domestic Integrated Wiring System testing standards are as follows:

Intelligent Building Engineering Quality Acceptance specification GB50339-2003

General test method for Electrical Characteristics of Integrated Wiring System YD/T1013-1999

Standard for communication cable cabling systems for commercial buildings ANSI/EIA/TIA-568B

Optical fiber cabling parts Standard ANSI/EIA/TIA-568BB.3

Information technology-integrated cabling for user buildings ISO/IECI1801: 2000 +
