Integrated wiring system is worth all of us to learn, features articles from the integrated wiring system, and two aspects of Introduction, a comprehensive introduction to the integrated wiring system, we want to help, I hope teaches you more knowledge.
Overview
Integrated wiring system is a modular, highly flexible building or buildings within the transfer of information between channels.It enables voice, data, video equipment and information exchange equipment and other information management systems connected to each other, but also make these devices with external communication networks.It also includes building exterior wiring network and application systems or telecommunication lines between devices connected all cables and related components.Integrated wiring system consists of different types and specifications of components, including: transmission media, associated connecting hardware (such as patch panels, connectors, sockets, plugs, adapters) and electrical protection equipment.These components can be used to build all kinds of wiring subsystems, which each have their specific uses, not only easy to implement installation, and can change with the needs of a smooth upgrade.
1. The characteristics of integrated wiring system
Compared with traditional cabling, integrated wiring system has many advantages, is unmatched by traditional cabling.Characterized mainly in that it has compatibility, openness, flexibility, reliability, advanced and economy.But also in the design, construction and maintenance also bring a lot of convenience.
(1) Compatibility: The first feature of cabling system is its compatibility.The so-called compatibility is itself is completely independent, and application systems are relatively independent, can be applied to a variety of applications.
In the past, as a building or a building within the group of routing voice or data lines, often is the use of different manufacturers of cable, wiring sockets, and joints.For example, the user switches commonly used twisted pair, coaxial computer system usually coarse or thin coaxial cable.These different devices use different wiring materials and wiring to connect these different plug, socket and terminal board is also different, incompatible with each other.Once the need to change the location of the terminal device or equipment, it must lay new cable, and installation of new sockets and plugs.
Cabling system can be voice, data and monitoring equipment, and other signals through the integrated planning and design, using the same transmission media, information outlets, cross-connect equipment, adapters, etc., to these different signals integrated into the wiring for a standardtransmission.Thus, this greatly simplifies wiring than traditional routing, can save a lot of material, time and space.
In use, the user can define a work area without the specific application of information outlets, only to a terminal equipment (such as personal computers, telephones, video equipment, etc.) into the information outlet, and then transfer between devices equipped with rooms andline equipment to do the appropriate wiring operation, the terminal equipment to be access to their systems by.
(2) open: the traditional route, as long as the user selected a device, it selected the corresponding wiring and transmission media.If you change to another device, then we should replace all the original wiring.For a building has been completed, this change is very difficult, to increase a lot of investment.
Integrated wiring system by an open architecture, in line with various international standards on the current, so it almost all the leading manufacturers of the products are open, such as computer equipment, switching equipment, etc.; and the corresponding communication protocol is also supportedsuch as ISO/IEC8802-3, ISO/IEC8802-5 and so on.
(3) Flexibility: the traditional wiring is closed, its architecture is fixed, to move or add equipment, it is quite difficult and cumbersome, or even impossible.
Standard cabling system transmission cable and associated connecting hardware, modular design, it is common to all channels.In a computer network, each channel can support terminals, Ethernet and Token Ring workstations workstations, all devices open and no need to change the wiring changes, simply change the application of appropriate equipment and on the patch panelnecessary to jumper management.In addition, the network can also be flexible, even in the same room as the user organizations to provide the necessary conditions for the flow of information.
(4) Reliability: the traditional way of wiring the various application systems as mutually incompatible, and thus tend to be in a building in a variety of cabling options.Building the system reliability to the reliability of the route chosen to ensure that when the application system wiring is not the time, can also cause cross-interference.
Cabling system using high quality materials and constitute a combination of a high standard the way of information transmission channel.All trunking and related connections are through the ISO certification, each channel must be tested using special equipment to ensure its electrical performance.Applications all use point to point wiring termination, a link failure shall not affect any other links of the operation, which for the link operation and maintenance and troubleshooting to provide a convenient, in order to protect the application system reliability.The applications often use the same transmission medium, thus spare each other to improve redundancy.
(5) nature: integrated wiring system uses hybrid fiber and twisted pair wiring, very reasonably constitute a complete set of wiring.
All wiring are in line with world standards for many types of communication, according to eight-core twisted pair link configuration.Category 5 twisted pair bandwidth of up to 100MHz, 6 categories of wire bandwidth up to 250MHz.According to the needs of users can lead to fiber to the desktop (Fiber To The Desk).Some use copper voice lines, data, part of the use of fiber optic cable, for simultaneous transmission of multiple real-time information to provide adequate bandwidth capacity.
(6) Economy: wiring cabling is more economical than the traditional, mainly integrated wiring can be quite a long time to adapt to user needs, and transform traditional wiring is very time-consuming and delay the loss of work is not in monetary terms.
Through the above description shows, cabling can solve the traditional routing approach has many problems, with the rapid development of science and technology, people share information resources increasingly urgent demands, particularly in the telephone business based communication network graduallytransition to the Integrated Services Digital Network, more and more attention to provide voice, data and video information transmission communication network.Therefore, the integrated wiring instead of a single, expensive and complex traditional wiring, is the "information age" requirement, but also the inevitable trend of historical development.
2. Introduction to Cabling System
Integrated wiring system should be open-star topology, should be able to support telephone, data, graphics, images and multimedia business needs.
From an engineering point of view, integrated wiring system can be divided into six parts, including three subsystems: wiring (horizontal) subsystem; Link (vertical) subsystem; buildings subsystems and work areas, equipment rooms, administration.Of course, for a building complex and building wiring systems, the need to consider the introduction of the cable to the external space (the line area).
2.1 Workspace
Need to set up a separate area of terminal equipment should be classified as a work area.Horizontal cabling subsystem work area should be extended to the workstation information outlet connection at the terminal device composed of cables and adapters.The service area of a workspace can be 5 ~ 30m2 estimates, or by building different applications and functionality to adjust the size of the area.Each work area with at least one information outlet used to connect telephone or computer terminal equipment, or requirements set by the user.Each work area should be supported by an information outlet telephone, computers, data terminals, and other terminal equipment setup and installation.
2.2 The horizontal cabling subsystem
Horizontal cabling subsystem information by the work area outlet, the information outlet to floor wiring devices (FD) of the wiring cable or fiber optic cable, wiring devices and equipment, floors, and jumper cables and other components, as shown below (figure.)
2.3 Vertical cabling subsystem
Vertical cabling subsystem building wiring between devices by device (BD) and equipment cables and jumpers and equipment to the floor between the trunk cable between wiring components, as shown below (not shown):
2.4 devices
Devices in a building of appropriate locations for each set of telecommunications equipment and computer network equipment, and building wiring devices, network management place.Integrated wiring system for engineering design, equipment installation of building wiring between the main device (BD), phones, computers and other equipment and the introduction of the host device can be combined fit together.Equipment, all within a total application of color-coded wiring devices use different types of wiring area.Equipment room location and size of the equipment should be based on the number, size, best network centers and other factors, considering the OK.
2.5 Management
Management response equipment, the transfer of the wiring between the equipment and work area, cable, information outlets and other facilities, according to a certain mode of identification and marking, and has a record of the document.
2.6 campus backbone subsystem
Campus backbone subsystem should be connecting the building cabling system between the cable and construction group wiring device (CD) and equipment cables and jumpers and so on.Campus backbone cables should be underground pipes or laying cable channel mode.The laying of the pipeline should follow the telephone copper or fiber optic cable into the bore of the pipe and design requirements.In addition to install should be set aside at least 1 or 2 spare pores for expansion.Complex subsystems with the laying of buried trench, if buried in the same trench as the other images, such as cable monitoring system should be clearly established common signs.
