Cat5e and cat6 twisted pair wires have entered the stage of diversified products and diversified classification. When installing the cabling system, people may have to choose products of Category 5, Category 5, Category 5, or Category 6. For the verification test of the cabling system, the standards for on-site testing lags behind products on the market. as we all know, the testing standard is required for the twisted pair link installed and tested on site. For example, T568ATSB67 and ISO11801.
At present, three category and five category twisted pair links have already met the field testing standards, and there are no testing standards for the six category. Cat5e standards-for cat5e, it is not long to complete its final test standards. Because the tested parameters, test limits, and experiment data have gradually reached an agreement. In this way, the standard may be announced around the fall of this year, and the cat5e system will certainly support the same operation of Gigabit Ethernet. New category 5 standards-Existing category 5 standards will still be retained. However, users of the current five-category system may want to know whether the installed five-category system supports Gigabit Ethernet. Therefore, an arrow at the end of the year may announce a new five-category standard, this standard adds some new test parameters and test limits. There is still a long time before the final completion of class-6 standards.
At present, many cable manufacturers have launched Cat 6 systems, and some users have installed these systems in some projects. However, today's Cat six Cable System is a dedicated system. The so-called special system refers to all the components in the cable link-the electricity supply, user wiring, and connectors-must be six types of products of the same manufacturer.
Currently, the component standards of category 6 systems are not the test standards) and have not yet been finalized for approval. Most of the performance indicators of the six types of systems that have been installed on site have been set up. Performance parameter indicators of some important links, such as attenuation, near-end crosstalk, and remote crosstalk, have been relatively stable. However, some parameter indicators of link performance may be modified, such as return loss. Indicators for Category 6 components are still under study, and many of the different proposals are still under consideration. However, it may take a long time to form the final industrial standard. Results of the dedicated system the current six types of systems are dedicated, which means that each manufacturer's product components have their own unique design and performance indicators. These components are specially designed and defined as the six-Class components. After they are connected together to form the final link, the proposed draft of the high-class Transmission Performance indicators can be achieved; components from different vendors are unlikely to interact with each other, especially connectors. Category 6 products of different vendors are not directly available, but cannot be physically connected. When A Vendor A's six-Class 8-core plug is used to insert the Six-class socket of Vendor B, this connection can not meet the Six-class transmission performance indicators. Using the Six-class Key Path that complies with the major component standards and is correctly installed, its performance parameters can achieve all the performance indicators of the link.
The user wiring Patch cables that are connected to the tested link in the basic link and the shaking head connected to the tester have a great impact on the transmission performance. Ideally, the impact of the user connection lines of these testers can be ignored, that is, their impact on the tested link transmission performance during testing is negligible. In fact, this kind of ideal situation is impossible, just to achieve this goal. Measure the performance of the near-end string with the same key path. One is to use the correct user wiring, and the other is to use a poor user wiring. The previous result passed the national test standard of the Key Path, and the other one failed to meet the lowest performance requirements. The measured value of the near-end crosstalk between the upper and lower ends of the test pole cast curve indicates that the change of the near-end crosstalk is very small. The only difference is that the user connection lines used for the two measurements are different. The first dark curve uses matching user wiring, and all connectors use products of the same manufacturer. The link passes the minimum requirements of the six types of links at all frequencies. Although the margin between the participating results and the limit value is relatively small, the proposed test criteria are still passed. Near-end crosstalk and ripple loss are two parameters most affected by the user's connection quality and link terminal connection. These two parameters are almost the most important parameters for meeting the performance standards of the six types of links. Dedicated interface hardware in order to test the performance of the six types of systems installed, the field Tester must use an 8-core modular connector that matches the electrical performance of the link to be tested, it is connected to the tested link. The basic Link interface adapter provides a fixed 2-meter user terminal to connect to the tester. To test the cat6 kV system of different manufacturers, different. KV interface adapters are required. The requirements for such applications may be temporary until the rules on the six-Class component standards are finally formulated and implemented effectively, there may be no need for different adapters to adapt to the links composed of six types of products from different vendors.
