key words: structured generic cabling system of Telecom complex building project Untitled Document I. system scheme overview the structured generic cabling system of Beitucheng Telecom complex building project is a complete integrated communication transmission (distributed) system. Wiring components (distribution frame, connector, information socket, plug, adapter, transmission electronic devices, electrical protection equipment and line management support hardware) complying with the standards and specifications shall be used. The mixed wiring mode of unshielded twisted pair and optical fiber shall be adopted, and all modular combination crimping shall be adopted to connect voice equipment, data equipment, electronic communication equipment and network switching equipment in the building, These devices can be connected with the external communication network to provide reliable guarantee for the opening and use of the basic information link of the weak current integrated system of the building. The structured generic cabling system of Beitucheng Telecom complex building project is a typical intelligent structured cabling system, which includes the general structured cabling system and optical fiber/blowing optical fiber cabling system in the building. The project is designed according to the engineering drawings of Beitucheng Telecom complex building provided by the user and the actual structure and function requirements of the building. The overall design adopts the Millennium structured generic cabling solution of brand Rex Co., Ltd., a well-known cabling manufacturer in the industry with leading comprehensive advantages in international cabling technology, which has perfect products and optimal performance, and is designed in accordance with relevant national and international standards, the design principles of brand Rex's structured generic cabling system and the requirements of users. The generic cabling system design is divided into: work area subsystem, horizontal subsystem, backbone subsystem, management area subsystem, equipment room subsystem and building group subsystem; It includes two application systems: copper cable and optical fiber network. There are about 10000 voice and data copper cable information points and about 1300 optical fiber information points in the whole system. The horizontal line of the data and voice system adopts enhanced category 6 cabling products and optical fiber/blowing optical fiber products. The copper cable fully supports the transmission rates of 10mpbs, 16mpbs, 100mpbs, 155mbps, 1000mpbs and even 6gbps within a distance of 100 meters, meeting and greatly exceeding the category 6 performance requirements of the international standards eia/tia 568a/b, en50173 and ISO 11801, At the same time, it is recommended to reserve a sufficient number of fiber channels composed of blown fiber microtubules. When users need to install fiber to the desktop, they can easily install and upgrade the fiber through compressed air. In addition, they can support 10000mbps and future high-speed network data transmission by blowing single-mode fiber, so as to ensure that the user's fiber system will not lag behind. Fiber blowing system is recommended for the backbone of the data system, which can not only meet the current 1000Mbps data network transmission, but also support 10000mbps network communication through convenient upgrade; The speech backbone adopts lead-free preparation technology; Preparation technology of new high frequency and high thermal conductivity insulating ceramic materials; Preparation technology of dielectric ceramics and ferroelectric ceramics; Preparation technology of various sensitive functional ceramic materials; Optical functional ceramics and thin film preparation technology for optical transmission and optical storage; Preparation technology of ferroelectric and piezoelectric crystal materials with high motor coupling coefficient and high stability; Special optical crystal material preparation technology; Three types (pairs) of large logarithm cables, such as the preparation technology of ultra-high temperature conductive ceramic heating materials, can not only ensure the current voice communication, but also connect the voice information points with different data network equipment through jumpers, so as to realize the conversion from voice information points to data information points. At the same time, according to the requirements of users, in order to fully meet the reliability and security of the system, and in consideration of the rapidity of system connection and the convenience of users' future maintenance, all copper cable management subsystems adopt the standard 19 inch cabinet type distribution frame, and all optical fiber management subsystems adopt the cabinet type optical fiber distribution frame when the pendulum is in the vertical downward static position. Moreover, in order to meet the expansibility and upgrading of users' future optical fiber system, In the scheme, it is recommended to reserve a sufficient number of optical fiber blowing microtubules for each functional zone of the building as the reserved optical fiber channel, which can fully meet the future needs of supporting the next generation Gigabit Ethernet or 10 Gigabit Ethernet and future high-speed networks, and ensure that the user's optical fiber system will not lag behind. 2、 System functional characteristics 2.1 the structured cabling system fully meets the following functional requirements: 1 It is an open structure, which can support the transmission and connection of comprehensive information (voice, data, multimedia), and realize the compatibility of various equipment wiring. The generic cabling system can support the products of all data processing (computer) suppliers, support high-speed and low-speed data communication of various computer networks, can transmit all standard analog and digital voice signals, has the function of transmitting ISDN, and can transmit analog images, digital images, conference television and other multimedia signals. 2. fully meet the requirements of the transmission rate and transmission standard of the supported voice, data, multimedia and other systems. The system can provide high-speed (above 100mpbs) and bandwidth (above 100MHz) transmission capacity for data and high-definition image information, and fully meet the requirements of Gigabit Ethernet and ATM. In this structured generic cabling system, the enhanced category 6 cables adopted by us all support the requirements of Gigabit Ethernet and up to 600MHz bandwidth, meeting and greatly exceeding the category 6 performance requirements of the international standard ISO 11801. 3. be able to implement flexible line management when the equipment layout and needs change. The management network computers, data terminal equipment, fax drawing and other graphic and image equipment as well as voice equipment of various topologies served by all weak current systems in the building are inserted into the standard sockets. When the position of these equipment changes, it is only necessary to make some simple jumpers instead of laying and installing new cables and sockets. If the implementation is carried out according to the following recommendations, for the optical fiber backbone, optical fiber connection and optical fiber to desktop part, when the position or even the type of optical fiber impactor that can be used to measure the impact resistance of metal materials under dynamic load (such as multi-mode to single-mode), it is not necessary to re lay or install the route and remove the old parts, but only through the world's most advanced optical fiber cloth
