So from a safety point of view , the use of shielded and fiber optic cabling systems . The building is characterized by a large transportation construction area , if it comes to China Unicom offsite building between the cable along the pipeline reflects the diminishing form is an extension of the type of star network . The main part of the cable routing is very long, fiber optic cabling system should be adopted .
For mechanical and electrical equipment when it comes to the issue of electromagnetic interference , the cable should also consider their shielding . Hospital is considered the most important problem of electromagnetic interference cable transmission bandwidth needs and medical devices , due to the large area occupied by the hospital , building more complex functional requirements , it should be considered as a multi-purpose building groups , according to the cable cloth placed between buildings designed in order to meet the needs of many conditions , the use of shielded wire + fiber optic cabling system is more appropriate.
Second, intermediate users , dealing mainly with integrated data , voice or multimedia message , with a certain size, but do not ask for information transmission speed to mid-range office buildings, factories, schools and the intelligence community as a representative. Such buildings typically in the wiring to fiber optic backbone , horizontal cabling using UTP copper ( or six ) , the use of three types of multi- line voice -pair copper cable . Schools such as cabling within the building is an architectural complex of the overall wiring , and more to take into account the construction of fiber-optic backbone network . Another school more functional, has a teaching building, laboratory base , public lecture hall , library, and student dormitories Museum , but the overall demand on the network is relatively not too high, so most of the system will choose the level of over five class cable. Of course , do not rule out some individual sites will take into account their needs, levels were six cable , such as the Science Museum .
Third, ordinary users , mainly in the transmission of information to be able to realize the basic needs , such as the common house. Cabling residential building has two characteristics:
· Completed using home wiring cabling box functionality , but does not process the information ( such as exchange, storage , processing, transmission ) ;
· The wiring management and processing of information , and have done together, should actually be called " home information wiring devices " , both the wiring function , but also on the telephone , information exchange and transmission networks , the family of three table Cc , emergency call , such as the family of intelligent control conversion and transmission of information . Generally use pure copper cabling , pay attention inexpensive.
In cabling product line , there is a line -home solutions , the program mainly uses a triangle module , using a specially designed line the way home , and can simultaneously transmit two- way data over a single Cat5e UTP cable door phone , save a lot of money for investors , with excellent value for money.
Each active electronic and electrical equipment may produce electromagnetic interference to disrupt network traffic. With increasing use of electronic devices , this problem is becoming more and more prominent. In selecting cables and cable routing considerations , and how to prevent electromagnetic interference in order to protect the communication is a very critical issue.
All network components selected , including connectors and patch panels must have measures in anti- EMI interference. When using shielded cable , cable and connectors are properly terminated and a good grounding cable jacket is a very important point . Any incomplete shield will reduce the protective shield , thereby reducing the resistance to electromagnetic interference (EMI) efficiency. Cable alignment should follow the manufacturer's recommended method , you should try to avoid potential sources of interference . Here, it should give full consideration to international standards and indicators related to cable traces the rapid development of the regulations. Fluorescent, elevator motors, automatic doors and air conditioning units, etc. are all potential sources of electromagnetic interference . The more obsolete equipment , electromagnetic interference generated greater . For those who can not avoid sources of electromagnetic interference and overcome , the use of closed metal pipes can provide additional protection for the wiring system . Specific or sensitive to electromagnetic interference in the environment , the use of optical fiber may be the only choice
