10 Gigabit copper Ethernet, a symbol of excellent cabling systems

This article introduces 10 Gigabit copper Ethernet. 10 Gigabit copper Ethernet may be a standard for measuring the quality of an excellent wiring system. Many people may not understand it yet, after reading this article, you must have gained a lot. I hope this article will teach you more things.

The discussion of the upcoming 10 Gigabit copper Ethernet (10GBase-T) solution will have a significant impact on the development of current and future excellent cabling systems. Standardization of 10-Gigabit copper Ethernet 10GBase-T is in progress. Many users want the performance of their cabling systems to support future development. For them, it is of great significance to support Ethernet 10GBase-T standard for 10 Gigabit copper cables.

The main driving force behind the development of this technology is the cost, and the actual application needs to reduce the cost. 10 Gigabit copper Ethernet 10GBase-T technology is designed to achieve 10 times the performance at 3 times the cost, measured by the most advanced Ethernet technology currently in use (measured by Gigabit Ethernet technology, the cost is three times, and the performance is 10 times ). For a wide range of implementations of 10-ge Ethernet, the use of fiber-optic transmission solutions has proved to be too expensive, so copper solutions have been developed.

Someone may ask: Who needs it? What happened to a Gigabit Ethernet or 1.2 Gigabit ATM system running on a 6-class cabling system?

Indeed, only some organizations that need to use data centers (IDS) will consider 10 Gbps copper Ethernet 10GBase-T over the next 5 to 10 years, however, let's take a look at the situation of Gigabit Ethernet in over five types of cabling systems, and think about people's views on such applications two to three years ago. You will have a new understanding of the development of things.

According to the general market concept, if we install all the six types of wiring, the device manufacturer will develop a Gigabit Ethernet device (1000Base-Tx) that runs cheaply on the six types of wiring systems, because category-6 Cabling systems provide higher bandwidth than category-5 cabling systems, there is no need for expensive interference filtering devices (DSPs) on network devices ). Therefore, the development of Ethernet to 10 Gigabit 10GBase-T will surely become a reality. The reason is that we have found a larger device demand than 1000Base-Tx, which is cheaper.

In fact, more data transmission leads to a greater demand for bandwidth. Previously, this will happen in the future. Therefore, the cabling industry will be relocated to a higher target. According to the results of various information, the current six types of systems have limited support for new applications. Basically, the standard six types of systems can meet the needs of all applications with over five types of systems, the support for new applications requires 6 or 7 new systems.

In fact, if you have an understanding of the work of the 10GBase-T Standard Workgroup for 10 Gigabit copper Ethernet, you will find that their announced cabling system support goals are as follows:

1, 4 connector twisted pair copper cable system Channel

2. F-level (Class 7) cabling channels with a length of 100 meters

3. 55-meter length, Class E (Class 6), cabling Channel

4. 100 m length New Class E (Class 6) channel (not yet determined)

In short, seven types of cabling systems can support 10 gbase-t on 100-meter channels, while six non-shielded excellent cabling systems may support 10G Ethernet over 55-meter channels.

In any case, before we accept these standards, that is, we accept 10 Gbps copper Ethernet 10GBASE-T running on six types of systems that have been deployed within 55 meters, there are still some outstanding problems that will affect the existing unshielded 6 types of systems to support new applications. The main problem comes from two different areas. First, for any unshielded cabling system that has been installed, the Crosstalk between different cables (Alien Crosstalk) it is a major problem that hinders its support for 10 Gigabit copper Ethernet 10GBASE-T; The second problem is the need to reduce insertion loss (attenuation), which needs to increase the diameter of the conductor in each wire.

1. Because the crosstalk between different cables needs to be reduced, the current installation method of the unshielded system needs to be changed. This change will affect the cable channels (Cable slots, pipelines, bridges) the design and construction will have a significant impact, and this change will have a great impact on the cost of installation of unshielded systems;

2. By using the shielded information module, the distribution frame can better reduce the effect of crosstalk between different cables;

3. Currently, the ICD distribution frame (110XC fish bone distribution frame) is difficult to meet the performance requirements of 10g copper Ethernet, unless shielding is used between each hitting port to reduce crosstalk between different cables;

4. The use of special jumpers on the distribution frame is also required, because normal Jumpers are also affected by crosstalk between different cables;

5. The size of the conductor in the cable needs to be increased because 10G Ethernet applications need to reduce the impact of insertion loss (attenuation.

To solve the above problems, people are trying the following methods:

1. All 6 and 7 types of systems must redefine their transmission quality standards. The transmission bandwidth must reach MHz to reduce the effect of crosstalk between different wires, some new transmission parameters must also be defined;

2. The system needs to provide better insertion loss (attenuation) performance, so a thicker wire will appear;

3. More tests are required to determine whether the current system supports new applications;

4. design new cables to meet new performance requirements.

In addition, there is a very important issue worth noting, that is, there is no indication that the RJ45 connector will be abandoned, so whether you are installing a 6-class or 7-class system, RJ45 connector systems should be an excellent choice.

In fact, the final result of the debate on 6 categories of excellent cabling systems is expected to be resolved within 18-24 months. Based on the above discussions, we believe that all existing technical solutions, products, and possible problems should be taken into account to protect the investment of users who have installed the latest cabling system.
