What issues should be paid attention to in the construction of office integrated network cabling?

The integrated wiring of the office will definitely involve the work surface of the decoration, which requires more coordination, and the progress of the project must also be carried out along with the progress of the decoration! In the office decoration, the integrated network wiring is a very important part, and it is one of the basic facilities of the entire office decoration. The network realization of the entire space needs to rely on it. So how to implement the office network wiring well?

Next, let’s take a look at the engineering implementation of office integrated network cabling and its five principles.

1. Office Cabling Requirements

The information sockets of office wiring are part of the horizontal subsystem of the wiring system. No matter how the office applications of the enterprise change, the office integrated wiring needs to meet our following requirements. Requirements for telephones: Use telephone switches to effectively connect the enterprise with the outside world and facilitate 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 at all times. We must carefully consider the wiring system in the following situations: before the construction of a new building, during the construction of a new building, when the old building is being renovated, when the company needs to move to a new location; when the company's telephone and computer applications increase, but integrated wiring has not yet been adopted; when the company's previous wiring system cannot meet the needs.

2. Installation location of information socket

For office building environments, office spaces include large open spaces and small rooms with four walls. Different installation methods are used for the panel installation of the workspace subsystem in these two forms. Small rooms do not require partitions, and information sockets only need to be installed on the wall; for large open spaces, the following two installation methods are used:

• Information sockets are installed on the ground: The metal bottom box installed on the ground should be sealed, waterproof, dustproof and have the function of lifting. This method has a high cost for design and installation. And because the office location of the staff cannot be predicted in advance, the flexibility is not very good. It is recommended to determine the location according to the function of the room and make pre-embedded, but it is not suitable for large-scale use to avoid affecting the appearance.
• Information sockets are installed on the wall: In this method, when the position of the partition board is not determined, RJ45 embedded sockets can be evenly installed at a certain distance along the walls around the large bay. The RJ45 embedded information socket should be 20 cm away from the power socket next to it, and the lower edge of the information socket and the power socket should be 30 cm away from the horizontal plane of the floor. When crimping the information module and the twisted pair, pay attention to the color matching and crimp correctly. There are two connection methods: 568A and 568B. Both methods can be used, but please note that only one method can be used in a system solution.

3. Office Cabling Cable Routing Method

Office cables can be routed directly through ceiling racks, placed in cable ducts, and buried in walls. Industrial standards allow for the introduction of junction points close to the connection location.

1. Use a light trough cable tray on the ceiling

This method is suitable for large buildings. The assembled trough-type cable tray that provides mechanical protection and support for horizontal cables is a closed metal bridge installed in the ceiling. It leads from the weak current shaft to the room with the information point. The line is led to the concealed iron box on the wall by iron pipes of different specifications pre-buried in the wall. The material of the cable trough is cold-rolled alloy plate, and the surface can be treated accordingly, such as galvanizing, spraying, baking paint, etc. The cable trough can be selected in different specifications according to the situation. In order to ensure the turning radius of the cable, the cable trough needs to be equipped with branch accessories of corresponding specifications to provide free turning of the line routing. In order to ensure the safety of the line, the trough body should have a good grounding terminal. The metal cable trough, metal hose, metal bridge and distribution line cabinet should be connected as a whole and then grounded. If the exact location of the information outlet cannot be determined, the cable can be coiled at the outlet in the ceiling when pulling the wire, and then lead to the information outlet after the specific location is determined.

2. Use ground cable trough for wiring

This method is suitable for large-spaced offices with dense ground-type information outlets. It is recommended to pre-embed metal wire ducts or wire duct floors in the ground cushion layer. The main trunk duct is led out from the weak current shaft, along the corridor to each room with information points, and then led to the information point outlets in the room by the bracket duct. The strong current line can be configured equally with the weak current line, but it needs to be separated in different wire ducts. In this way, each user can be provided with an integrated panel including data, voice, uninterruptible power supply, and lighting power outlets, truly achieving office automation in a clean environment.

4. Other office wiring details

The information points (information sockets) arranged in each office should be arranged in the same horizontal direction as the office power sockets, and the spacing should be about 30cm; such wiring is mainly to facilitate the simultaneous connection of the user's power supply and twisted pair network cable, and also to facilitate future repair and maintenance; currently, it is best to use a 4-port wiring panel for each information socket, two network interface wiring (one external network, one internal network), two voice points (one internal line, one external 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 information point should be equipped with a power socket. Sometimes, it is also necessary to lay video points, fire extinguishing system probes, monitoring points and other wiring details in appropriate locations in the office.

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, and can plug various equipment terminals into standard information sockets. The office wiring system is compatible with voice and data equipment from different manufacturers and uses the same cables and patch panels, the same plugs and modular jacks.

The network cabling of various offices should consider about 60% redundancy based on the number of computer equipment when building the enterprise network, so as to avoid network communication failures caused by insufficient number of ports in some offices when connecting network segment expansion devices such as hubs and switches. The office cabling system adopts modular design. Except for the horizontal cables fixed in the office, all other connectors in the cabling system are modular standard parts, which are easy to expand and reconfigure. The office cabling system can easily expand the current and future voice, data, network, interconnection equipment and monitoring equipment, which is a truly advanced technology for the future.

5. Office wireless network "wiring"

In order to adapt to the changes in the market, the company has made adjustments internally. After the adjustment, the number of people in the original office has increased, and the original wiring ports can no longer meet the office needs after the adjustment. In addition, the working methods of the company have also changed, and temporary personnel often handle business in the office. If the company's office environment is an old building; or because the company's development requires the office location to be fixed in one building, etc., wired wiring cannot be used.

At this time, you can consider establishing a wireless network to provide network access for mobile office workers; using wireless network "wiring" can allow users to have an office area that can be moved at any time. This is very useful for companies that need to add office nodes at any time and need network connection to office areas. "Mobile office" allows these newly added office access points to use all shared devices such as printers and storage devices in the office. The operation is as simple as inserting a wireless network card. This makes up for the shortcomings of wired wiring, combines wired and wireless, and meets the actual needs of enterprises for online office work.

Five principles for office network cabling:

1. Consider the complementarity of wired and wireless office integrated wiring: according to the specific environment of the building and office requirements, decide whether to use wired wiring or wireless in the case of long-term or temporary use of the network; generally speaking, it is to combine wired and wireless, give full play to their respective strengths, to achieve our purpose of online office.

2. The flexibility of office integrated wiring needs to be considered: how many information points are used in each office location? The office wiring should not only meet the current needs of users, but also meet the expectations of users for future information systems; and data and voice twisted pair wiring should be interchangeable to form a complete wiring system.

3. The comprehensiveness of office integrated wiring needs to be considered: office wiring needs to meet the transmission requirements of various analog or digital signals, and combine the wiring of all languages, data, images, and monitoring equipment into a standard wiring system. A standard connecting line is required between the equipment and the information outlet to connect them through a standard interface.

4. The rationality of the office's integrated wiring needs to be considered: the wiring directions of the office's strong and weak electricity should be reasonably matched, not interfere with each other, and have a beautiful appearance; users' use of computer power, telephone, and network cables at the same time should be convenient for operation and future operation and maintenance.

5. The reliability of the office integrated wiring system needs to be considered: the products used in the office wiring system must be certified by international organizations. The design, installation and testing of the wiring system must use ANSI EIA/TIA 568A and GB/T50311-200 as wiring standards and comply with domestic wiring specifications and testing specifications.
