How to effectively network cabling

Along with the rapid development of society, various industries, departments and home users of the information needs more and more, the development of computer communication network technology for the realization of large capacity, rapid delivery provides the possibility, so more and more units and home users began to consider how to effectively layout, install network communication lines, So that in the future can easily connect to the local area network or the Internet, so as to achieve high-speed, high-capacity data, voice, image transmission, it can be said that the effective network cabling for building communications, computer networks and other systems to build a strong foundation. Then we how to the building or other network communication system to effectively decorate the network line, the following author on the basis of their own point of understanding, and you talk in detail in the network wiring should pay attention to the key issues.

1, improve the network cabling the importance of understanding

Only fully understand the importance of network cabling, we can in the actual wiring process, so that the network layout more systematic, standardized and rationalized. Structured and systematic cabling of the network allows unit users and individual users to take full advantage of rapidly evolving technologies that can have a substantial impact on all systems in any device. The systematic layout of network lines, because of the use of common standard edge system factors, this can be very convenient and fast communication equipment installation, commissioning, replacement and maintenance, so that users of this investment can achieve a more satisfactory efficiency returns. Through the system layout of network cable, not only can ensure the flexibility and scalability of networks and future upgrades, but also can be faced with the system maintenance workload and the cost of system maintenance, as far as possible to control at the minimum. The system layout of network line can be regarded as a platform for the whole network communication system to construct a good engineering performance. The use of this platform for the entire building or the entire communication system network communication has great flexibility and versatility, but also has a very good performance price ratio, for example, according to the experience of the author's wiring statistics, Cabling the entire floor or the entire building can reduce the network communications maintenance staff to half the original. Because the systematic and structured network wiring system is a star-shaped physical structure with multiple functions, it can be applied to the network system with different topology. Just make some wiring changes on the right node without moving cables and equipment. Therefore, once the network system changes, to rationalize the layout of the cable can reflect its own advantages. ---http://bianceng.cn (computer science)

2, wiring needs of the network products should be the same manufacturer

As a result of wiring used in the network products, such as ordinary 5 twisted pair or crystal first is a weak signal transmission, a little careless are likely to affect the overall performance of network communications. At present, there are many kinds of network products in the market, some manufacturers of network line quality may be better, some manufacturers may produce crystal head use effect is more obvious, but also some manufacturers to produce the network interface module cost-effective is the highest, in order to be able to all the advantages of these products are concentrated, Many wiring people often simply think that if these network products combined to a system cabling, may make the network communication signal attenuation to the minimum, so as to achieve the best communication effect. In fact, this understanding is not correct, once these different manufacturers of high-performance products integrated in a system to use, not only can not achieve the communication effect we imagine, but the communication effect will become worse. Because the impedance of the internal material of the network products of different manufacturers is not the same, the subtle differences in the impedance may have a great influence on the signal attenuation of the high speed communication network, thus affecting the communication quality of the whole network communications system. Perhaps some people say that they are in the wiring is the use of different manufacturers of network products, as if the speed did not significantly reduce it? In fact, a system using different network products, the impact on the speed of the network under 10M is really very small, sometimes can not be compared by hand, but if 100M or more high-speed network systems using different network products to wiring, the final exchange speed will be a significant change in the network. Therefore, I suggest that regardless of which network system cabling, we would be best to use the same manufacturer of the network products, so there may be the manufacturers to provide us with the communication quality assurance of about 15 years.

3. Reasonable planning and design before wiring

Because cabling should take into account the integrity and system, so this requires us before wiring, should be cautious, conscientious, do a full investigation, collect relevant wiring information, such as the need to wiring the design of the building drawings, wiring needs to consider the matter and details, and should take into account the wiring of the construction progress, Application of requirements and economic conditions, and other aspects of the content. If the building is still in the construction of the wiring, the wiring should be based on the building's architectural requirements, building on the wiring, the specific needs of the line to carry out the implementation, for example, put forward the upper and lower floors between the channel specifications, embedded some pipelines and so on. These requirements can be reflected in the design of the building, so that at the same time the construction of some wiring in the prophase of the project, to avoid many of the defects of late construction, reduce duplication of work, improve work efficiency, to achieve reasonable and easy to do. If it is built on the basis of the building and interior decoration project synchronized with the integrated wiring, it should be based on the actual observation and analysis of the existing building materials and decoration design of the integrated wiring.

4. Do not use the network line

Many designers in the layout of network lines, in order to save investment costs, a network cable is often used to connect devices at the same time, for example, it is possible that they would split a pair of wires from the twisted pair to connect to the phone, or they could connect two pairs of wires to two network interface modules, which would seem to improve the utilization of the network line. In fact, this first-line multi-use approach to the efficiency of the network communication is very large, for example, if you want to use the network line more, you have to untie the cables that are twisted around each other, so that the twisted pair will break, and the near-end string of twisted pairs will become larger, The numerical increase of the near-end string has a great influence on the transmission and exchange speed of the network line; Moreover, as the speed of network Exchange is constantly upgraded, the Gigabit Speed switch network is also gradually popularized, and gigabit network using Full-duplex transmission exchange, this way will be a network line contains 8 of the cable all use, So from this point of view, the network line to do a lot of use is not conducive to the entire network system in the future upgrade.

5, to strict wiring construction quality

When wiring a large building or communication network system, relying on the strength of computer technicians is not enough, many units are invited to build construction personnel to participate in the entire wiring system of the project, and these constructors most of the network or computer knowledge, they will often put the network wiring and telephone lines, The wiring and other lines are confused, therefore, these workers in the specific wiring, will not consider the various details of network wiring, such as network line and interface between the link between the connection module, cable and Crystal head of the link between the wire and the network cable stranded and other details, if these construction workers are not strict construction quality, Without paying attention to these details, it will have a great impact on the transmission performance of the network line.

And for users, they detect the network layout of the only means of good or bad, is the entire wiring completed, simple use of network detection command "ping" to see the network connectivity, as long as the network of Ping Pass the word that the entire wiring work is qualified. In fact, after the network wiring is completed, not simply to test the network connectivity is so simple, you also need to see whether the network transmission speed to reach the nominal value of the network products, a poor construction quality wiring will be in the transmission speed greatly discounted. In addition, we must pay attention to the layout of the network cable system for all-round testing, for example, first of all through the network cable tester to see the net line of the 8 cable connection sequence and test is connected, this test for ordinary users can also be very convenient, as long as the purchase of a set of detectors can be, for large, When testing a system network with high transmission requirements, it is also necessary to check the overall signal loss of the point-to-point connection through a dedicated test. If the loss signal is too large, then the construction quality is certainly not clearance, in addition to the cable line of the near-end crosstalk numerical test, we must test all the line pairs between the near-end crosstalk, The worst line pair combination must meet the minimum performance index requirement, in order to guarantee the most basic guarantee of network system operation. In testing the network cable, we also have to do a good job marking work, the number of points at the information points and wiring racks marked with labels and on the floor plan, so that the system for future management, use and maintenance. General acceptance is found at both ends of the problem, this may be the wiring racks did not do a good job, may also be the module is not done, there is a possibility is the top board when the screws into the network cable caused by short-circuit phenomenon, and so on. After the complete marking and detection of the network system, we should rearrange the cable plan and make the correct mark on it for future maintenance.
