Zhejiang Lansheng: General Outline of Integrated Wiring System

The engineering design of intelligent buildings and intelligent architecture parks should be based on actual needs, and the following three types of integrated cabling systems can be selected:

Basic type: Applicable to the situation that the configuration standard in the integrated wiring system is low, and use copper core twisted pair cable networking. The basic integrated wiring system is configured as follows: Each work area has an information outlet; each work area has a four-pair twisted pair cable for the distribution cable; clip-on transfer hardware is used; the trunk cable in each work area is at least There is 1 twisted pair.

Enhanced: For use in moderately configured standards in integrated cabling systems, copper core twisted-pair cable networking. Enhanced integrated cabling system configuration is as follows: Each work area has 2 or more information outlets; each work area distribution cable is 2 4 pairs of twisted-pair cables; clip-on or plug-in transfer hardware; each work The trunk cable in the area has at least 2 pairs of twisted pairs.

Comprehensive type: It is suitable for occasions where the configuration standard is high in the integrated wiring system, and the optical fiber and copper core twisted-pair cable are used for hybrid networking. Comprehensive integrated wiring system configuration should be based on the basic and enhanced integrated wiring system based on the addition of fiber optic cable system.

The integrated cabling system should be able to meet the transmission rate requirements of the supported data systems, and should use appropriate levels of cables and transmission equipment.

The integrated cabling system should be able to meet the transmission standard requirements of the supported telephone, data and television systems.

Comprehensive wiring system engineering design, selection of cables, optical cables, all kinds of connecting cables, jumpers, and wiring equipment and other hardware facilities, shall comply with the provisions of ISO/IEC11801:1995(E) international standards to ensure system indicators Implemented.

Integrated and line system should be set Han Xian computer information management system. Manually log in the working status information of the hardware facilities related to the integrated cabling system. The status information includes: the usage and use department of the equipment and cables, the topology structure of the local area network, the transmission information rate, the configuration status of the terminal equipment, and the occupation hardware number and color The functions of the target, the link, and the main characteristic parameters, the integrity of the link, and the fault record. You should also log in to the device location and cable orientation content, as well as the building name, location, area code, floor number, and room number.

When designing the system, the cables, connecting hardware, jumpers, connecting cables, etc. selected by the system must be consistent with the selected category. If shielding is used, the entire system must be shielded and the continuity of the shielding needs to be maintained.

New system

Category 5 cable system (EnhancedCat5): It is a new type of cable system produced after improving the performance of some existing UTP twisted pairs. There are many performance parameters, such as Near End Crosstalk (NEXT) and attenuation crosstalk ( ACR) has been improved, but its transmission bandwidth is still 100MHz. Currently, there are two types of unshielded cables and shielded cables.

Category 6 cable system (Cat6): A new level of cable system, in addition to a large increase in performance parameters, its bandwidth will be extended to 250MHZ. In fact, this level of cabling system has been proposed very early, and is currently widely used. There are shielded and unshielded cables.

Category 6A Cable System (Cat6A): In the category above category 6 cable systems, in addition to a large increase in performance parameters, the bandwidth will be extended to 500 MHz for 10 Gigabit transmission. Currently in the development stage. Only shielded cables, and because the frequency becomes higher, it must be achieved using pair-to-pair shielding.

Category 7 cable system: Category 7 cable system is a cable standard proposed by Europe. Its implementation bandwidth is 600MHZ, but its connection module structure is completely incompatible with the current RJ-45. Due to the increase in frequency, it is necessary to add a copper mesh layer to the outer layer. Only the shielded cable is used to shield the aluminum foil from the outer copper mesh braid.

Category 7A cable system: Category 7A is a higher grade cable, its implementation bandwidth is 1000MHZ, and its corresponding connection module structure is completely incompatible with the current RJ-45. At present, GG45 can be seen on the market (backward compatible with RJ45 ) and Tear module (can complete 1200MHz transmission). Due to the increase in frequency, it is necessary to add a copper mesh layer to the outer layer. Only the shielded cable is used to shield the aluminum foil from the outer copper mesh braid. Cables for 40 megabytes and 100,000 megabytes.

Category 8 cable system: Category 8 is currently the highest level of transmission cable known, its implementation of the bandwidth plan is 1500MHZ, and finally what it looks like, it also needs to wait.
