With the spread of computer applications, along with the rapid development of network technology, the campus network has become an essential school information infrastructure. The implementation of the campus network has provided a guarantee for schools to adapt to new developments and make fuller use of existing teaching resources to teach and manage. As the physical basis of intelligent network building, campus cabling uses a variety of transmission media to connect the communication management device and the terminal. Its performance can affect the normal operation of the network and the length of life. Therefore, designing a scientific, rational and optimized campus cabling system is the key point to further play a variety of network equipment functions, achieve a good development of school's information and communication technologies and improve application management level.

Introduction

According to GB/T 50314 "Intelligent Building Design Standards" about the demarcation of ten categories of building regulations, school building includes full-time higher education institute, senior high school, vocational senior middle school, junior middle school, primary school, nursery and kindergarten etc. Different levels school has different scale, environment and personnel, so requirements of the campus cabling system will also be different. However, in terms of cabling systems of all kinds of school, network requirement of higher education institute cabling system is the most comprehensive. So this article will introduce the campus cabling system mainly based on higher education institute.

The Campus Cabling System Features

In our country, the area of a full-time higher education institute uaually nearly one thousand acres, some even thousands of acres. There are a number of buildings in a school, such as teaching building, comprehensive building, laboratory buildings, art building (including the campus theater, campus dance halls, campus cultural centers), libraries, teachers’ apartments, students’ apartments, gymnasium, conference centers, schools’ hospitals, canteens and so on. In order to satisfy all requirements of these different buildings and applications, we must think over how to design the campus cabling system properly. In general, a campus cabling system has following features.

Campus Cabling Diversity

Building diversity

Each building is different from its architectural style and function. In view of different floors, areas and information points, we should make different plans. For tall buildings, the location of the equipment room should be considered carefully. For information intensive constructions, the position of each floor of the telecom should pay attention to. Because if the setting is reasonable, it can save a large amount of horizontal cable. For large bay places, we should consider not only the distribution of information points but also the length of the level of information points. Besides, in some campus gymnasium, auditorium and other places, we should also need to consider whether to set CP boxes and some other issues.

Application diversity

In colleges, a variety of buildings determine its different applications. So we should make different design plan to satisfy different buildings. Teachers apartments and student dormitories can be cabling design according to ordinary residential buildings. Comprehensive building and administration building can be carried out according to the way commercial office planned and designed. Data storage and computing centers can be designed according to the data center to meet a variety of information throughout the campus switching, aggregation and storage. The experimental and research laboratory building as an important place, which may exist strong radiation and corrosive material. So it is a very dangerous place, we should take not only the electromagnetic interference, environmental impact, but also the potential life safety issues into account. Therefore, these sites suggest using the whole screen or fiber class industrial grade high flame retardant wiring products, such as using fire-retardant grade reach CMP / OFNP grade or industrial grade reaches IP67 cabling products.

High-Speed Transmission of Information

High-speed transmission of information for campus cabling system is already a pressing task. A variety of multimedia transmission, video transmission and other large flow of data communication are growing very fast. The multimedia educational system, remote network education system, digital libraries, data centers are some places where the information is very concentrative, which needs to ensure a gigabit to the desktop and 10 gigabit for the backbone. If the budget allows, it is best to ensure gigabit to the desktop and 40G/100G for the backbone so as to prepare for the future development. And for classroom apartment or student residence, it should try to make gigabit to the desktop. Because the development of the Internet is so fast. Therefore, in product planning, we should not only meet the existing information and communication needs, but also to do with a certain forward looking.

Stability and Security of Information

In the campus network, the reliability and security of information transmission is very important, because it not only directly related to the use of campus communications network, but also to the entire campus of internal and external education system problems. Instability in the event of information or information leaks may not only affect education, and may also bring significant social problems. So requirement of campus intranet information is to ensure that the information is transmitted reliability and security in any case. When we design a campus cabling system, we must choose a good quality cabling products and use shielded cabling system or fiber optic cabling system to avoid interference or disclosure of information.

The Campus Cabling System Considerations

Disaster Prevention

Disaster prevention is necessary for any cabling system. In campus cabling system, there are many disasters we should prevent, such as such as earthquakes, lightning, flood, fire, etc. Actual situation in different school may also be different. In general, the following two types of disaster are common.

Lightning stroke

Campus cabling system is different from general cabling system. It usually has more buildings than other places. Information interconnection between the various buildings and buildings or information interconnection between the construction and data center must through all kinds of outdoor cables, so the campus backbone cable corresponding will increase, which brings challenges for the outdoor cabling lightning protection. Because once a root trunk cable is struck by lightning, if the grounding system goes wrong, then hundreds of thousands of volts high voltage transient will pass along the cables between devices, resulting in equipment damage, data loss and significant losses. So into good grounding system and surge protection near incoming line is very important.Of course, if you want to achieve more secure and avoid outdoor cables in danger of being struck by lightning, you can also all use non-metallic reinforcing fiber optic cable in the outdoors.

Fire disaster

In addition to natural disasters, the fire is the most serious disaster caused by the loss of personnel and property at present. In campus, most of the buildings are crowded places. In addition to selecting a variety of fire related materials and good fire prevention measures, cabling system cables fire retardant also has become essential. So we advise to use cables which consistent with the relevant fire rating in horizontal routing. Because school is a special place, once the fire happened, it will result in severe damage to people and property. In addition, for campus cabling system, other disasters such as the computer room of the need to guard against seismic reinforcement and cables rat bite also need to pay attention to.

Management

There are many application systems and extensive information distribution points in a campus cabling system, which is a big challenge for systems management and maintenance. The traditional label drawing and handwriting management, or the way to use the computer for documentation record and preserve are inapplicable for such big cabling system. Therefore, if the budget allows, we advise to use intelligent management system in big campus cabling system to improve cabling system maintenance and management level and enhance network security.

Intelligent Building Digitization

In campus intelligent cabling, in addition to our previously mentioned, the campus radio systems, fire alarm systems, electronic fence system, monitoring system, LED large screen display systems, etc also included. These systems are all in the transition to digital. Because a digitized school will collect, dispose, integrate, storage, transmit and apply the information of teaching, research, management, technical services and life services, so that to make the digital resources to be fully optimized. By achieving the digitization of environment, resources and applications, we can build a digital space on basis of traditional campus to improve the operating efficiency of the traditional campus, expand the traditional campus business functions, and realize the full information of the education process so as to improve the management level and efficiency.Therefore, the basic transmission channel of all variety of intelligent systems in campus will also jumped to Gigabit, and even 10 Gigabit network requirements. In the design and planning, we should consider the application of digitization. In which the products can be selected copper Cat 6, cat 6a, cat 7 products, fiber optic cable can be selected OM3 or OM4 multimode cables and single-mode cables. However, for fire alarm systems and campus broadcasting system, products of which should be chosen to meet the high flame retardant properties. If possible, it is best to choose a high fire retardant cables. Because it does not lead to a fire occurs due to the rapid combustion of the cable causes the system to malfunction.

Conclusion

Campus cabling system though complex, but as long as we grasp the core features of the cabling system, clear the basic requirements of cabling system standards, understand the applications and functions of different systems and buildings, then it is not difficult to design and planning. Even the schools have hundreds of buildings and information communication application systems, it all based on basic principles of cabling. Therefore, as long as they are in accordance with their respective needs and applications for planning and design, you can complete a set of perfect campus cabling system.
