1. Signs of maturity of six types of products:
First of all, the formal enactment of the six types of standards shows that the current six types of cabling products are already mature products. The earliest known as Category 6 cabling products have been for several years now. With the continuous improvement of technology and production levels in the past few years, most of the cabling vendors' six types of products have matured, which has prompted the final standard. Passed formally. What is the significance of this to the user? With six types of formal standards, it means that their products have become more mature, so users can safely choose six types of products. In addition, after the installation of the six types of products, certification tests can be performed using formal standards, so that reliable assurance can be obtained. Before the official standard was promulgated, some manufacturers used the manufacturer's own standards to conduct wiring tests. These standards often differ from international standards. After the formal 6-category standard, this problem was completely solved.
2. Consistency of standards:
An important feature of the new standard is that the North American 568B and European ISO standards are already very close. The difference between the two is small. In this way, it is very convenient to use in actual operation. It doesn't matter which standard you use. In the past, using one of the standard tests and passing the result, and using another standard test to get the result of not passing the result will no longer occur.
3. Test model changes:
The new standard also has important changes to the test model, which both abolished the definition of the basic link and defined the permanent link (Permanent Link). The test of the basic link includes testing the error of the access line, and the six types of standards are very strict and the margin is very small, so that the error of the test line can not be ignored. Most of the adapters currently on the market for testers are basic link adapters. For example, Fluke Networks' DSP-4000/4100/4300 series digital cable testers are mostly equipped with basic link adapters. It is easy to cause large errors in the test process, and even results in erroneous test results, misjudged those links that are qualified by themselves as unqualified. The biggest difference between basic link adapters and permanent link adapters is that the permanent link adapters are very high quality and very durable, and introduce very small errors. Therefore, many basic link adapters must be replaced with permanent link adapters to meet the requirements of the six types of tests. For example, the DSP-4000/4100/4300 series digital cable testers from Fluke Networks are optional or can be equipped with their own. There is a permanent link adapter. There is no change in the definition of the Channel test, but it should be pointed out that the actual significance of the current test channel is not significant. Because the channel test requires a patch cable. It should be pointed out that the Category 6 jumper must be purchased by the original manufacturer, and the user himself can no longer do it. The purpose of the channel test is to check whether the link can support the application of the network, but at present there is no actual high-speed network application.
4. More stringent construction process:
The installation of a good Category 6 cabling project places stringent requirements on the construction process. The link margin of the six types of systems is already very small, and the NEXT margin of ordinary links is only 2 to 5 dB (depending on the length of the link). It is difficult to pass the six types of construction using five types of construction processes. result. For example, many Type 6 cables now use high-quality, lighter-rotating spools that are designed to reduce the pulling force of the split cable. In addition, twisting and squeezing of the cable may have undesirable consequences. During the construction process, the use of inferior tools, card pliers, and card cutters will degrade the performance of the link and fail the test. Therefore, all users who intend to install Category 6 systems must pay special attention to the construction quality of the contractor or contractor. The best option is to use a construction team with six types of construction experience and evaluate the completed construction projects.
5. The importance of certification testing:
Six types of system certification tests are more important than the original five or five. This is because the investment in the six types of systems is very large, so it is necessary to carry out rigorous testing of their own investments to ensure the quality of investment. In addition, the current network applications based on Category 6 twisted pair have not yet reached the practical stage, that is to say that currently installed six types of systems can not currently use the actual network to verify whether it can well support high-speed networks, such as 1000Base-T and 1000Base-Tx. So certification testing is the only way to ensure that high-speed network applications can be supported in the future. The relationship between the network and media and the future development will be described later.
The final release of the six types of cabling standards is of great significance. It marks the maturity of six types of products; there is a basis for certification testing; the investment of users has a more reliable guarantee; at the same time, it further promotes the development of network media and networks.
