What issues should I pay attention to in the integrated network cabling of the office?
The office's integrated wiring will definitely involve the renovation of the work surface, the need to cooperate more, the progress of the project will also follow the progress of the renovation! In the office decoration, integrated network cabling is a very important part of it, and it is one of the infrastructures of the entire office decoration. The network implementation of the entire space needs to rely on it. So what issues should be paid attention to in the office's integrated network cabling? The following Boloom Benlang integrated wiring small series is simple for everyone to introduce.
First, the needs of office wiring
Office wiring information outlets are part of the horizontal subsystem of the cabling system. Regardless of how the office applications of the enterprise change, office cabling needs to meet our requirements. The requirements for the telephone: the use of telephone switches to effectively connect the enterprise with the outside world, while facilitating internal calls. Requirements for computer networks: The integrated wiring adopts a star structure and can support current and future network applications - 100Mb Fast Ethernet, 1000Mb Gigabit Ethernet. Requirements for image transmission: analog images, digital images, conference television, etc.
In a modern office environment, communication must be stable and reliable. In the following situations, we must carefully consider the wiring system: before the construction of the new building, in the construction of the new building, when the old building is remodeled, when the enterprise needs to move to a new location; the company’s telephone and computer applications increase, but not yet When using integrated wiring; when the company's previous wiring system can not meet the demand.
Second, the installation location of the information outlet
For the office building environment, there is a large open space in the office space and a small room with four walls. Different installation methods are used for the panel installation of the work area subsystems in these two forms. Small rooms do not require a dividing board, information outlets only need to be installed on the wall; for large open spaces, the following two forms of installation are used:
1 Information socket is installed on the ground
The metal back box required to be installed on the ground should be sealed, waterproof, dustproof and can be lifted. This method is costly for design and installation. And because the staff's office location cannot be predicted in advance, the flexibility is not very good. It is recommended that the location be determined according to the functional use of the room, but it is not suitable for mass use, so as not to affect the appearance.
2 information socket mounted on the wall
In this method, when the position of the partition plate is not determined, the RJ45 buried socket can be uniformly installed at a certain distance along the wall around the wide open space. The RJ45 buried information socket should be kept at a distance of 500px from the power socket next to it. The low edge of the information socket and power socket is 750px from the floor level. When the information module is crimped with the twisted pair, pay attention to the color label pairing and make the correct crimping. The connection mode is divided into two modes: 568A and 568B. Both methods can be used, but note that only one method can be adopted uniformly in a system solution.
Third, the office wiring cable routing method
Office cables can be routed directly to the ceiling frame, placed in the wire trough, and embedded in the wall. Industry standards allow the introduction of joints close to the joint.
1 Way of using light trough cable trays with ceilings
This method is suitable for large buildings. A fabricated trough-type cable tray that provides mechanical protection and support for horizontal cables. It is a closed metal bridge that is installed in a suspended ceiling and leads from a weak electric shaft to a room with information points, which is embedded in the wall. Different sizes of iron pipes lead the wires into the concealed iron box on the wall. The material of the wire trough is cold-rolled alloy plate, and the surface can be treated accordingly, such as galvanizing, spray coating, baking paint, etc. The wire trough can be selected according to different conditions. In order to ensure the turning radius of the cable, the trunking needs to be equipped with branch fittings of corresponding specifications to provide a free route for route routing. In order to ensure the safety of the line, the tank body should have a good grounding end. The metal trunking, metal hose, metal bridge and distribution line cabinet need to be connected integrally, and then grounded. If the exact position of the information exit cannot be determined, the cable can be first The cable is placed in the outlet of the ceiling, and after the specific position is determined, it is led to the information outlet.
2 Adopt ground trough routing
This method is suitable for the office room in the large open space. If there is dense ground-type information export, it is recommended to pre-embed the metal trunking or trunking floor in the ground cushion. The main trough is led out from the weak electric shaft, and leads along the corridor to each room with information points, and then the bracket slot is led to the information outlet port in the room. The strong electric line can be equally arranged with the weak electric line, but it needs to be separated by different lines. In the slot, this can provide each user with an integrated panel including data, voice, uninterruptible power supply, and lighting power outlet, which can be used to achieve office automation in a clean environment.
Fourth, the office's other wiring details
The information points (information sockets) arranged in each office should be arranged in the same horizontal direction as the power sockets of the office, and the spacing is about 750px; the wiring is mainly convenient for the simultaneous connection of the user's power supply and the twisted pair network cable, and is also convenient. Maintenance and maintenance in the future; currently it is best to use four-port wiring panel, two network interface wiring (one external network, one internal network), two voice points (one inner line, one outer line), and network data for each information socket. It can be used interchangeably with voice cabling; design information points and voice points for each office according to the actual needs of the enterprise, and power outlets should be provided near each information point. Sometimes in the appropriate location of the office, you need to arrange video points, fire system probes and monitoring points and other wiring details.
The office wiring system is closely linked to the office decoration and office furniture. The office wiring system is a standard wiring system that integrates all voice, data, image and monitoring equipment. It can insert a variety of equipment terminal plugs into the standard. The information inside the socket. The office wiring system is compatible with voice and data devices from different manufacturers, and uses the same cable and distribution frame, the same plug and module jacks.
The network cabling of various offices should consider about 60% of redundancy on the basis of the number of computer equipment in the construction of the enterprise network, avoiding the network being built soon, some offices connected to the network segment expansion equipment such as hubs and switches due to insufficient number of ports, resulting in network communication. error occured. The office wiring system is modular in design. Except for the horizontal cables fixed in the office, all the connectors are modular standard parts, which are easy to expand and reconfigure. Office cabling systems make it easy to extend current and future voice, data, networking, interconnected devices and monitoring equipment, making them truly future-proof.
Fifth, the office wireless network "wiring"
In order to adapt to the changes in the market, the internal adjustment of the enterprise has been carried out. After the adjustment, the number of personnel in the original office has increased, and the original wiring port can no longer meet the adjusted office needs. And the way companies work has changed, and there are often temporary staff who handle business in the office. If the corporate office environment is an old building; or because the development of the enterprise requires that the office location cannot be fixed in a building, etc., wired wiring cannot be performed.
At this time, it is possible to consider establishing a wireless network to provide network access for mobile workers; using wireless network "wiring" allows users to have an office area that can be moved at any time. This is useful for companies that need to add office nodes at any time and need to connect to the 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. The operation is as simple as inserting a wireless network card. This will make up for the shortcomings of wired wiring, and combine wired and wireless to meet the actual needs of enterprises to access the Internet.
