6 Types of data cabling is the mainstream wiring technology thinking

6 Type of data cabling is not large and medium-sized cities Office, commercial class building wiring system of the mainstream technology? In our country's data wiring market, 6 kinds of products launch only a few years, "6 kinds of wiring system is the mainstream technology" in the industry have heard. By June 17, 2002, ANSI Tia/eia formally passed the 6 wiring standards, and in June 24 as the appendix of TIA/EIA-568B officially published, named 568b.2-1. It was also rumored that the International Organization for Standardization (ISO) would also approve 6 cabling standards, with the standard number ISO 11801-2002. As a result, "6 types of wiring systems are the mainstream technology" in the industry also more wind. In fact, this is more "wind" than "raindrops" mostly, until the beginning of this year, the review of 2003 years, the vast majority of manufacturers of 6 categories of product sales are only the total distribution of products sales volume of about 30%. Moreover this "30%" mainly uses in the big and medium-sized cities office, the Commercial class building, (this "30%" increases the manufacturer, the wiring dealer's income, only is makes the 5E class and the telephone line use, this "30%" should belong to who? A large number of residential buildings are rarely laid. A media survey shows that wiring has begun to be pushed from the commercial sector to residential. Nevertheless, in the current access network of the main feed line to achieve the basic optical fiber, the community's broadband network construction, "The last 100 meters", is generally still using the 5E and 5 types of stranded cable wiring. So, is not when the sales of 6 categories of products than the overall distribution of products sales volume of 50%, it must be large and medium-sized cities Office, commercial and other buildings of the mainstream wiring technology?

What is "mainstream technology"? The industry has already been discussed by experts: "Mainstream technology" refers to advanced, mature, practical technology. The manufacturer sells, is adopted by the user. is "use" equal to "practical"? Not necessarily.

6-Class cabling is used to transmit 1000base-tx or gigabytes of data information, however, so far, it is obvious to all that the fact is: whether on the main line, or to the desktop, 6 types of cabling products are rarely used to transmit 1000BASE-TX or gigabit data information. Read a variety of published in the integrated wiring technology of the newspaper and magazine, can not find a practical application of 6 types of wiring technology examples. Reality tells us, "6 cabling technology is the mainstream technology of wiring system", has not really been "practical" verification. If the 6 type cabling products are commonly used for transmission of 100BASE-TX, 1000BASE-T (4 to the core line of the full use) of data information, or for the transmission of voice information, then should say: 6 kinds of products have not been due to the application. There is no real "practical" verification of the 6 types of wiring technology and products, of course, it should not be said that it is mature. At present, 6 kinds of wiring products in the market has a considerable amount of possession (about 30%, recently reported up to 50%), is not applied in the pull, but mainly hype, blindly follow, the results of the herd. (Computer science)

A design scheme says, 6 class cabling downward application in the 5 class link, the performance parameter is more than 5 kind of wiring has the more margin, uses 6 kind of wiring, after the 10mbps~100mbps transmission distance may reach 150m, may solve the project to appear some difficult points. 6 types of wiring as such applications, it should be said, is not the development of 6 types of wiring products, the main intention.
