Thinking about the 6th category of data wiring is the mainstream wiring technology
Is Class 6 data wiring the mainstream technology of office and commercial building wiring systems in large and medium-sized cities? In my country's data wiring market, the sixth category products have only been launched for a few years, and "the sixth category is the mainstream technology of wiring systems" has been heard in the industry. On June 17, 2002, ANSI TIA/EIA officially passed the Class 6 cabling standard and was officially published as an appendix to TIA/EIA-568B on June 24, named 568B.2-1. At that time, there were rumors that the International Organization for Standardization (ISO) would also approve Class 6 cabling standards, with the standard number ISO 11801-2002. In this way, "Class 6 is the mainstream technology of wiring systems" is even more popular in the industry. In fact, this is much more "wind" than "raindrops". Until the beginning of this year, looking back at 2003, the sales volume of the six-category products of most manufacturers only accounted for about 30% of the total sales volume of integrated wiring products. What's more, this "30%" is mainly used in office and commercial buildings in large and medium-sized cities (this "30%" increases the revenue of manufacturers and cable manufacturers, but is only used for Class 5E and telephone lines. Who should this "30%" be?) A large number of residential buildings are rarely laid. Media surveys show that cabling has begun to move from commercial to residential. Despite this, when the main feeder segment of the access network is basically fiberized, the "last 100 meters" of the broadband network in the community are generally still used to use Class 5E and Class 5 twisted cable wiring. So, when the sales volume of Class 6 products exceeds 50% of the total sales volume of integrated wiring products, it is definitely the mainstream wiring technology for office and commercial buildings in large and medium-sized cities?
What is "mainstream technology"? Experts in the industry have long discussed: "Mainstream technology" refers to advanced, mature and practical technologies. Sales by manufacturers and adopted by users. Does "adoption" equal "practical"? uncertain.
Class 6 cabling products are used to transmit data information of 1000Base-Tx or more. However, so far, it is obvious to all: whether on the main line or to the desktop, Class 6 cabling products are rarely used to transmit data information of 1000Base-Tx or more than gigabit. After reading a variety of newspapers and magazines that publish comprehensive wiring technology, I can't find a practical example of applying six types of wiring technology. Reality tells us that "Class 6 wiring technology is the mainstream technology of wiring systems" and has not been truly verified "practical". If Class 6 wiring products are commonly used to transmit data information of 100Base-Tx and 1000Base-T (all 4 pairs of core wires) or are used to transmit voice information, then it should be said that Class 6 products have not received the appropriate application. There are no Class 6 cabling technologies and products that have been truly "practical" verified, and of course it should not be said to be mature. At present, the reason why Class 6 wiring products have a considerable share in the market (about 30%, and recently reported 50%) is not because of the application, but mainly because of hype, blindly following the trend, and chasing the trend.
A certain design plan says that when Class 6 wiring is applied downward in Class 5 links, the performance parameters have more margin than Class 5 wiring. After Class 6 wiring is used, the transmission distance can reach about 150m at 10Mbps to 100Mbps, which can solve some difficulties in the project. As such an application, Class 6 cabling is not the main intention of developing Class 6 cabling products.
