General standard for generic cabling

Abstract: in China, even if the newly designed buildings check whether the joints of the oil circuit system are tightened, the previous wiring technology is often still used, resulting in the incompatibility of the wiring of various systems and difficult to adapt to the development of new technology. Moreover, the pipelines are overcrowded, and the huge investment in wiring is often repeated. This situation will also become prominent with the growth of companies, enterprises or organizations, the renewal of equipment, the change of personnel and the change of office environment. Any addition or change may cause overall changes. Reverberation room sound absorption measurement ISO 354 ⑵ 003 seriously affects work efficiency and enterprise operation

key words: Generic Cabling Standard Design Elements untitled documents with the rapid development of the information industry, data transmission has become a very critical resource in companies, enterprises and government departments. Data must be accurately and quickly transmitted between various communication equipment, data processing equipment and display equipment. For this reason, the company and government departments all require to improve the communication system in the shortest possible time and adjust the wiring system as needed

in China, even in newly designed buildings, the previous wiring technology is often used, which makes the wiring of various systems incompatible and difficult to adapt to the development of new technology. Moreover, the pipelines are overcrowded, and the huge investment in wiring is often repeated. This situation will also become prominent with the growth of companies, enterprises or organizations, the renewal of equipment, the change of personnel and the change of office environment. Any addition or change may cause overall changes and seriously affect work efficiency and enterprise operation

Plastic sealing machines in China have made great progress

especially with the emergence, application, promotion and development of ISDN (integrated service data), ATM (asynchronous transmission mode), fddi/tpddi (optical fiber distributed data interface/twisted pair distributed data interface) and building automation system, the original wiring system will not meet the requirements. Therefore, it is urgent to find a more reasonable, optimized, flexible, stable and scalable cabling technology. It can not only meet the current requirements, but also meet the challenges of the distribution system in the future

the structured generic cabling system meets the needs of social development, creates an environment that supports multiple products and manufacturers, and realizes long-distance information transmission. Generic cabling system · general provisions

should meet the requirements of openness, flexibility, modularity, reliability, scalability and economy

· system description

structured generic cabling system is a complete set of cabling systems. The system has an open structure to provide compatibility with many manufacturers' products, and has modular scalability and user-oriented characteristics

the cabling system combines unshielded twisted pair and optical fiber to connect various equipment and networks in buildings and buildings - voice and data communication equipment, switching equipment, fax equipment and network management system produced by many manufacturers

· design elements

are suitably installed outside the telecommunications outlet

wiring subsystem cables and corresponding jacks

1) 4 pairs of 100 Ω unshielded twisted pair (UTP) are connected to 8-core information jacks

2) two pairs of 150 Ω shielded twisted pair (STP) are connected to the shielded information jack

3)62.5/125 μ M optical fiber cable is connected to optical fiber standard interface

4) the dual media hybrid cable is connected to the dual media hybrid information socket

trunk subsystem cable and length

62.5/125 μ M 0.5 wire diameter 100 Ω UTP 150 Ω STP

(1) the main cross connection to the intermediate connection 1500m 300m 700m

(2) the intermediate connection to the management area 500m 500m 500m

(3) the computer management system of the main cross connection to the management area 2000m 800m 700m

generic cabling system should be able to record the working status information of various hardware facilities at any time

it can display: floor plan, location of all hardware and equipment rooms, component location of wiring subsystem and trunk subsystem

shielded wiring system should be adopted in case of CO frequency interference. If unshielded wiring is close to the TV cable, it will produce the same frequency interference

· design standard

the first level standard can meet the requirements of high-quality high-frequency broadband and integrated service digital communication

(1) each working area (M2) shall have at least one double hole or porous 8-core information socket

dual media mixed information jack with multiple jacks can be used in special working areas

(2) cross connect hardware using crimp jumpers or plug-in jumpers

(3) the wiring subsystem adopts class 5 unshielded autoclaved aerated concrete slab gb15762 ⑴ 995 twisted pair, class 5 shielded twisted pair, super class 5 twisted pair, optical fiber or mixed group

(4) the trunk line adopts the mixed group of copper cable and optical cable or all adopt the optical cable group

(5) the corresponding information Jack in each work area has an independent horizontal wiring cable leading to the floor distribution frame
