Matches 6 types of cabling systems

Since the proposal of cat6 cabling systems, discussions on their interconnectivity have always existed. What is interconnectivity? Simply put, it is the ability to mix components of different manufacturers in a structured cabling system.
Structured Cabling has been around for quite a long time before the introduction of cat6 cables. Currently, structured cabling must be over five categories. This is the lowest configuration for Gigabit Ethernet, because four pairs of two-way simultaneous transmission performance tests are performed based on the measurement and installation system. Although the maximum operating frequency is less than m, the performance in this band has been improved. Transient crosstalk NEXT) is more restrictive than that of Category 5 systems, which requires less transient crosstalk than Category 5 systems ). Over five categories are 6 categories and our discussion on Interconnectivity is ready. Interconnectivity is a mechanism to ensure that all the plug-ins of relevant manufacturers can work together with the plug-ins of other manufacturers. Although Interconnectivity is a topic of more than five categories of systems, it was also one of five categories of systems. It is necessary to further explain the significance of meeting the requirements of six categories of systems.
Independent tests show that, as long as the components meet the requirements of TIA and ensure intercommunication, on-site testing of the 6-class cable system, with different 3-level testers, the results may not be much different.
Category 6 Cabling systems were proposed by ISO in September 1997, followed by TIA. There are many differences between Category 6 and Category 5 and Category 5 standards:
· Maximum bandwidth of 200 MHz
· Design Based on MHz Detection
· UTP and STP Solutions
· Includes all tests of over 5 categories and new parameters
· ISO defines the permanent link and channel of Class 6 lines as Class E
In the early stage, the development of category 6 was similar to Category 5 and Category 5. Six Types of connection hardware, such as plug and socket, are being developed simultaneously. These two components are connected together or developed as paired devices. Developing an 8-pin module plug or socket does not have to participate in the corresponding part. Therefore, this practice is acceptable.
However, unlike category 5 and Category 5, Category 6 includes many significant improvements to the 8-pin module plug or socket, which leads to the following situation: when the paired plug-and-outlet meets the requirements of six types of standards, the open system nature of various types of cables in the past has been damaged. The entire topic of interoperability involves the improvement of the separation of 8-pin module plug and sockets, which requires a method called de-embedding, which can give six types of cabling systems an open nature.

The comparison of the near-end crosstalk loss of the six types of sockets in four different manufacturers in Single Channel Configuration shows the rationality of the interoperability estimation.
On-site testing by different manufacturers
Various manufacturers develop their own test plug and sockets. If their systems work smoothly, it seems that everything is going well. Most connection equipment vendors work with field tester vendors to develop a basic link adapter that includes an 8-pin module plug that can meet their requirements, as a result, field testing of 6 basic links is not a problem.
In the first six types of development, the plug-in line of plant A matches the outlet of plant A, and the plug-in line of plant B matches the outlet of plant B, however, it is seldom considered whether the plug-in line of plant A matches the socket of plant B. In fact, in the early stages of development of 6 categories, components of hybrid A and B manufacturers may only meet the standards of 5 or even 5 categories in terms of performance.
Recent 6 categories of development have affected the installation of permanent links) on-site testing and the configuration of 6 categories of active devices in the future. No one is worried about the matching of any category-5 cabling system with any source hardware such as hubs, switches, routers, and NICs. However, when these devices need to run at MHz bandwidth, that is, they need six types of wiring systems. Without interconnectivity, it means that the connection hardware of some manufacturers can only match with some specific active products.
Soon, people realized that only the broad market for intercommunication was the development direction of six types of connected hardware and connectors. To achieve this goal, people have made a lot of effort to design a specific protocol to achieve independent development of plug-in wires that can match other plug-in sockets) and sockets, the premise is that others also meet the performance requirements.
De-embedding Protocol
The standard plug and outlet introduced with the de-embedding protocol can help manufacturers develop and test their own connection products to ensure that they can match the standard plug outlet. If the connection hardware of all manufacturers can match the standard plug-in, you can be sure that they can match each other. A tia team is responsible for developing detailed issues about the de-embedding protocol. However, the de-embedding formulation takes a long time from the structure to the structure, from the experiment point to the experiment point, or even from the test to the test. This agreement has also become one of the final disputes over the adoption of six types of standards.
Both the real-part measurement and the virtual-part phase must determine the compatibility between the plug and the socket. After the plug and outlet performance values include Vector Measurement and phase) are determined, the connectivity is just around the corner. The standard plug helps the manufacturer to develop a socket that complies with the six types of standards. Standard sockets help manufacturers develop interconnected connection wires that comply with 6 categories of standards.
Once again, in the comparison of the consumption of the six types of connectors in four different manufacturers, the similar curves show the rationality of the interoperability estimation.
Permanent link test
The qualification and installation of all 6 types of systems requires a level 3 Tester for permanent link testing. This test, in theory, is a real test of the mounted cabling device after deducting the impact of the test device cable and connector as a permanent link adapter. The link adapter contains smart functions using microchips), which can automatically calculate the impact of the adapter on the test and remove it from the results. Since these adapters need to be widely adapted to different systems of various vendors, interoperability issues become crucial.
Once again, in the comparison of the consumption of the six types of connectors in four different manufacturers, the similar curves show the rationality of the interoperability estimation.
Although a considerable effort has been made to limit the 8-pin module plug of different manufacturers to a tightly controlled range, not all manufacturers' hardware can match all the link adapters. The result is that any link adapter may be able to adapt to a certain number of structured cabling systems, but not all. The user has the following question: "Which tester should be used to test a specific cabling system ?" And "Will the same result be obtained with another tester ?"
Initially, the field tester manufacturer provided the Tester Based on Different connection hardware manufacturers-specific link adapters. This means that each cabling system must have its specific link adapter to complete the required permanent link test. This poses a problem to everyone: Tester manufacturers, hardware manufacturers, vendors, and installers. The tester manufacturer realized that there must be a better way to perform permanent link testing for Category 6 systems. Most testers provide standard or general permanent link adapters they support. This means that the six types of connection devices must be able to connect with all these different link adapters-each with a terminal plug from different manufacturers.
Benefits of compatibility
These data indicate that it is possible to achieve interoperability between 6 well-designed connection devices. At the same time, as long as the components comply with the TIA standards and meet the communication requirements, the field tests of 6 types of systems with different 3-level testers may have little difference. The six types of systems need to be as open as Category 5 and Category 5, so that the industry can fully accept this technology.
In the Comparison of Three 6 categories of permanent link testers, similar curves show both interoperability and differences between testers.
