OM3, OM4 multimode fiber and single mode fiber of integrated wiring

OM3, OM4 multi-mode fiber, single-mode fiber, fiber-to-desktop, fiber-to-user, fiber-to-civil building user unit applications, fiber has the advantages of transmission distance and information security, in residential areas, fiber and fiber access systems cooperate , forming a multi-service platform, providing conditions for the access of broadband information. The optical fiber distribution system is mainly developed according to the user's demand for business, the demand for the network, and the demand for the image. In the future, in everyone's network home, a large number of optical fibers will be used, and its advantages such as good security, fast speed, strong anti-interference ability, fast transmission speed, and high transmission quality have been recognized. The application of optical fiber is a trend, which is no problem technically, the key is the price of the optical port of the network equipment.

Shielded wiring system. Considering information security, there are many applications of this type of wiring system. For example, some governments, banks, and confidential departments that have high security requirements usually use shielding systems.

Electronic patch panels and management software. The electronic distribution frame mainly manages the ports directly in real time, and records the usage at any time through hardware and software. It is mainly to ensure the security of the network, and at the same time, it can save the amount of operation and maintenance, greatly reduce the maintenance cost, and improve the work efficiency.

End-to-end solution. It is from the port of one work area to the port of another work area or linking with the external network to provide a comprehensive solution, which makes the application very convenient for users. Now many wiring manufacturers are doing this from the perspective of building electrical. overall service.

Room wiring. The data center computer room wiring that everyone is concerned about has different requirements from office wiring, emphasizing the wiring and environment of the computer room. Special emphasis is placed on regional wiring, and the level of product selection is also high.

High-density devices are used. The volume of optical and electrical plug-in device modules is reduced, the installation density is increased, and the manufacturing process level is improved, so that the function remains unchanged, but the space occupied is reduced, especially in the application of data center wiring engineering.

The power wiring system uses the wire pairs of the integrated wiring to transmit signals and provide power. There are two ways to use integrated wiring for power supply, one is to supply power to two pairs of lines, and the two pairs of lines transmit signals, and the other is to transmit signals and power supply at the same time. It is very advantageous to use the TCP/IP protocol for the terminal equipment of the network, which can greatly reduce the power sockets of strong electricity.

Industrial grade wiring. Industrial-grade wiring products need to ensure the normal transmission of information in harsh environments. For example, under outdoor conditions, the production site of industrial and mining enterprises. Industrial-grade wiring puts forward higher requirements on plug-in devices in terms of waterproof and dust-proof, so it provides the basic conditions for the application of information network in industrial production.

For the application of high flame retardant cables, although the cost of such products is high, the cables can be laid open, which is conducive to maintenance and system expansion. For this type of product, our choice of fire rating does not depend entirely on the material, but only needs to meet the corresponding fire test standards. At present, these products are more widely used in some special places such as airports and hospitals.

General wiring attention problems

Home wiring system. There are two concepts: one is to complete only the wiring and management functions, and the other is to complete the wiring management function and store, process and exchange various information. Domestic manufacturers have been relatively successful in home wiring, which is more in line with China's situation. The home wiring system can play a positive role in the integration of information networks and the integration of residential wiring pipelines, and it also meets the requirements of national regulations and policies. This point, should make correct propaganda and guidance to real estate developers. As an industry, home wiring will have certain development prospects as long as it adapts to China's national conditions, the application of developers, and the needs of users.

High-precision engineering test instrumentation and identification are used. With the improvement of the level of the wiring system, for the detection of wiring channels and links, the accuracy of the instruments used is higher, and the requirements for the localization of the recorded documents will also be proposed. The correct representation of the label content and the selection of label materials in the project provide a guarantee for the normal operation and maintenance of the project.

General wiring precautions 1: Hardware

To be compatible in the selection of network equipment, try to make all network equipment use the products of one company, which can minimize the incompatibility between high-end and low-end or even different equipment of the same level. And don't choose network basic materials without quality assurance, such as jumpers, panels, network cables, etc., in order to save dozens of dollars. These things will be placed in the ceiling or wall when wiring, and it is difficult to solve the problem when it occurs. At the same time, even the products of big brands should be checked for quality with professional tools before installation.

General wiring precautions 2: Wiring

When we complete the structured wiring work, we should take away the excess wires and equipment to prevent ordinary users from randomly connecting these wires. In addition, sometimes, users privately use a device such as a one-point-two-line head, which will also cause broadcast storms in the network. Therefore, it is necessary to follow a strict management system when wiring. Do not leave any components behind after wiring, because users are generally not familiar with the network, and when a problem occurs, they are likely to go to the doctor in a hurry, and they will use the redundant equipment casually, making the problem more serious.

General wiring precautions three: anti-magnetic

Why can electromagnetic devices interfere with network transmission speeds? Because the electrical signal travels in the network cable, and a magnetic field is generated near the high-power electrical appliance, this magnetic field will act on the nearby network cable to generate a new electric field, and the signal will naturally be weakened or lost. It should be noted that in addition to avoiding the interference source, the connection method of the network cable connector is also crucial. No matter whether the 568A or 568B standard is used to make the network cable, it must be ensured that 1 and 2, 3 and 6 are two pairs. Core wire, so as to have strong anti-interference ability. In structured wiring, the route of the network cable must be designed in advance, away from large radiation equipment and large interference sources.

General wiring considerations four: heat dissipation

In a high temperature environment, equipment always fails frequently. Why is this happening? Readers who have used computers know that when the CPU fan is not well cooled, the computer system often freezes or restarts automatically, especially for network equipment. The high-speed CPU and core components need to be in a suitable working environment. operation, too high a temperature can damage them. Equipment cooling is a must, especially for core equipment and servers, which need to be managed in a dedicated computer room, and also need to be equipped with cooling equipment such as air conditioners.

General wiring precautions 5: Connect cables according to specifications

It is well known that there are many kinds of network cables, such as crossover cables, straight-through cables, etc. Different cables have different uses in different situations. If the confusion type is used arbitrarily, the network will be blocked. Therefore, special attention must be paid to distinguish the types of cables when structured cabling. The use of cables that do not meet the requirements will cause the problem of network failure. Wiring experience: Although many network devices currently support the DIP jumper function, that is to say, it can be used normally regardless of whether you connect the positive line or the reverse line. But sometimes the device does not have the DIP function, and only if you pay special attention to the type of wiring when connecting, can you avoid unnecessary failures.

General wiring precautions 6: Reserve enough network access points

This is indeed the case. In many cases, future upgradeability is not considered in the structured cabling process. The number of network interfaces is very limited, which is just enough for immediate use. If the residential layout changes in the future, the above problems will occur. Therefore, it is necessary to reserve twice as many network access points in advance in structured cabling. As we all know, the development of the network is very rapid. A few years ago, it was still working hard for 10Mbps to the desktop, and now it is 100Mbps, and even 1000Mbps to the desktop. The scalability of the network needs our attention. No one wants to renovate and expand the cabling system after only using it for 2 to 3 years. Therefore, it is very important to reserve redundant access points so as to meet the needs of future upgrades.
