Layout design principle and implementation of office network

The wiring system is the network in the building or the complex, and is the foundation of realizing Intellectualization. It not only communicates the voice and data communication equipment, the Exchange equipment and other information management system in the building, but also connects these devices with the communication network outside the building. To achieve office computer and related office equipment Information Interface Network, and ensure its flexible use, use stability, long-term use, the appearance of beauty.
　　
and office wiring as the user's final use of information points (information outlets), placed on the wall location, use is convenient, the number of information points and the future problems can be easy to maintain the office network wiring must be considered. Therefore, the Office of Strong and weak electricity (power supply and image, data, voice) lines of the trend and other factors are our planning and design of the scope, so the office wiring Network, the details determine success or failure. We design the idea is to use the Office wiring System standards for implementation, so easy management and maintenance, system design has a certain advanced, consider the future of high demand applications.
　　
First, the Office wiring Network design principle
　　
1. Comprehensive
　　
Office wiring needs to meet a variety of different analog or digital signal transmission needs, all the language, data, images, monitoring equipment wiring in a set of standard wiring system, equipment and information exports only need a standard connecting line through the standard interface to connect them.
　　
2. Reliability
　　
Office wiring system used products must be certified through international organizations, wiring system design, installation, testing to ANSI Eia/tia 568A and GB/T50311-200 for wiring standards, follow the domestic wiring specifications and test specifications. (Computer science)
　　
3. Flexibility
　　
Each office location to use how many points of information, office wiring not only to meet the user's current needs, but also to meet the users of the future information systems system expectations; and the data, voice twisted-pair wiring should be able to exchange, constitute a set of complete wiring system.
　　
4. Rationality
　　
The Office of the weak and strong electricity wiring to the reasonable collocation, non-interference, and to the appearance of beauty; the user simultaneously uses the computer power supply, the telephone, the network cable must facilitate the operation, facilitates the later operation maintenance.
　　
5, wired and wireless complementarity
　　
According to the building's specific building environment and office requirements, long-term or temporary use of the network, such as the decision to use wired wiring or wireless; In general, it is wired and wireless combined to play their own strengths, to achieve the purpose of our online office.
　　
Second, the implementation of Office wiring Network
　　
1, the Office wiring needs
　　
Office cabling Information Sockets as part of the wiring system, regardless of how the Office application changes, office cabling needs to meet our following requirements.
　　
Telephone requirements: The use of telephone exchanges, enterprises and the outside world to effectively connect, while facilitating internal calls.
　　
Requirements for the computer network: integrated wiring using a star structure, can support the current and future network applications--10MB Ethernet, 100Mb Fast Ethernet, 1000MB Gigabit Ethernet.
　　
The demand for image transmission: Analog image, digital image, conference TV and so on.
　　
Modern office environment, communication time to ensure stable and reliable. When the following conditions are present, we have to carefully consider wiring system: in the new building before the construction, in the new building, in the old buildings, when the relocation of the enterprise to relocate, in the company's telephone, computer applications, but not the use of integrated wiring, in the enterprise before the wiring system can not meet demand.
　　
2, the installation location of information sockets
　　
For office environment, office space has Big Bay, also have walls small room. Different installation methods are used for panel installation of the workspace subsystem in both forms. Small rooms do not need dividers, information outlets need to be installed on the wall; for large bays, choose the following two types of installation methods:
　　
1) Information socket installed on the ground
　　
The metal bottom box required to be installed on the ground shall be sealed, waterproof, dustproof and capable of lifting and lowering. This method is of high cost for design and installation. And because the office location of the staff can not be foreseen, so flexibility is not very good, it is recommended that the function of the room to determine the location after a good burial, but not suitable for a large number of use, so as not to affect the beautiful.
　　
2) Information socket installed on the wall
　　
This method can be uniformly installed at a certain distance from the wall around the large bay with the RJ45 embedded socket in the position of the separator plate is not determined. RJ45 embedded information outlets and their adjacent power outlets should be kept 20cm distance, information outlets and power outlets along the low edge of the floor level 30cm. Information module and twisted-pair line, pay attention to color label matching, the correct crimping. The connection mode is divided into 568A and 568B two ways, both of which can be used, but note that in a set of system solutions can only be unified one way.
　　
3, Office cabling cable Line Way
　　
The office cable can go directly to the ceiling rack, place the grooves into the wall, and the industrial standard allows for the introduction of a junction near the junction.
　　
1 adopt the way of light groove cable tray with ceiling
　　
This approach applies to large buildings. A rack-shaped cable tray that provides mechanical protection and support for horizontal cables, is a closed metal bridge, installed in the ceiling, from the weak shaft leading to a room with information points, in the wall by the embedded in the different specifications of the iron pipe, the line led to the wall of the dark box.
　　
The material of the groove is cold-rolled alloy plate, the surface can be treated accordingly, such as galvanization, spray, paint, etc., the line groove can choose different specification according to the situation. In order to ensure the turning radius of the cable, the grooves need to be equipped with the corresponding specifications of the branch accessories to provide route routing of the turn freely.
　　
In order to ensure the safety of the line, the groove body should have good grounding end, metal wire groove, metal hose, metal bridge and distribution of the cabinet need to connect the whole, and then grounding, if you can not determine the exact location of information exports, pull cable can be the first line in the ceiling of the outlet, waiting for the specific location, and then lead to information exports.
　　
2) using the ground line trough line way
　　
This method is suitable for large-bay office, with dense ground-type information export situation, it is proposed to first in the ground floor cushion embedded metal wire groove or slot floor. The main groove is drawn from the weak shaft and leads to the rooms with information points along the corridor, and then use bracket groove to guide the information points in the room outlet, the strong electric circuit can be equal to the weak line configuration, but need to be separated in different slots, so that each user can provide a data, voice, uninterruptible power supply, The integrated panel of lighting power outlet is really made to realize office automation in a clean environment.
　　
4, the office other wiring details
　　
The information points (information outlets) arranged in each office should be in the same horizontal direction as the office's power outlet cloth, and the spacing is about 30cm; this wiring is mainly convenient for the user's power supply and twisted-pair cable connection at the same time, but also easy to maintain after maintenance; At present, the layout of each information outlet is best to use 4-port wiring panel, Two network interface wiring (an external network, an intranet), two voice points (an inside, an outside line), and network data and voice wiring can be used interchangeably; According to the actual needs of the enterprise, design the information points and voice points of each office, and each point of information should be equipped with a power outlet nearby. Sometimes in the office of the appropriate location also need to cloth video points, fire system probes and monitoring points such as wiring details.
　　
Office wiring system and office decoration and office furniture is closely connected, office wiring system is a set of standard wiring system, integrated all the voice, data, image and monitoring equipment, can be a variety of equipment terminals plug into the standard information outlets. Office wiring system for different manufacturers of voice, data equipment are compatible, and the use of the same cable and wiring racks, the same Plug and module jack.
　　
A variety of office network cabling in the enterprise network construction when the number of computer equipment to consider about 60% of the redundancy, to avoid the network completed soon, some offices due to insufficient number of ports and connected network segment expansion devices such as hubs, switches caused network communication failure.
　　
Office wiring system using modular design, wiring system in addition to fixed in the office of the horizontal cable, all the rest of the connectors are modular standard parts, easy to expand and reconfigure. The Office cabling system can easily extend the current and future voice, data, network, interconnect equipment and monitoring equipment, which is the advanced technology of the real future.
　　
5, Office wireless Network "wiring" ("Activity Office")
　　
In order to adapt to the changes in the market, the internal adjustment of the Enterprise, the original office after the adjustment of personnel, the original wiring port can not meet the adjusted office needs. And the way the business works has changed, there are often temporary staff in the office to deal with business. If the Enterprise office environment is an old building, or because the development of enterprises need not be fixed in a building, such as the situation can not be wired wiring.
　　
This is the time to consider the establishment of wireless network for mobile office staff to provide network access, the use of wireless network "wiring" can be used to have a mobile office area. This is useful for companies that need to add office nodes at any time and need a network to connect to an office area. The "Active office" enables these newly added office access points to use all the shared devices, such as the original printers and storage devices in the office, simply to plug in a wireless card. This will make up for the shortcomings of wired wiring, will be wired and wireless combined to meet the actual needs of enterprises to access the office.
