Luo Cong, an important technology of 10G Network
10 GBASE-T is an important technology for transmitting data from 10G networks, and has been widely used since its introduction in 2006.
10 GBASE-T (ten gigabit copper cable) is an Ethernet specification connected by copper cable twisted pair, corresponding to the IEEE 802.3an standard issued in 2006, which enables 10 Gbit / s transmission on unshielded or shielded twisted pair (super six or more), with a maximum transmission distance up to 100m. Overall, the network using 10 GBASE-T technology has two remarkable features:
1. When we deploy 10 GBASE-T technology in the network, the traditional infrastructure (such as network cable, wiring frame, etc.) can still be used;
2. Megabit copper cable (10 GB ASE-T) can be connected to a high-density giggigabit switch, providing an economical and efficient 10G interconnection scheme.
Why is the 10 GBASE-T so widely used? That’s because it has several advantages:
Backward compatibility: The 10 GBASE-T standard acts as an interoperable technology that is compatible with existing Gigabit Ethernet switches (usually used with Cat6a or Cat7 network jumpers), easily upgrading to 10G networks while reducing cabling costs.
Low latency: It is well known that the delay of 1000 BASE-T is generally submicroseconds to 12 microseconds, while 10 GBASE-T is more than three times lower than 1000 BASE-T(about 2 microseconds to 4 microseconds) due to large data throughput,
Easy to use: Ten gigabit copper cable (10 GBASE-T) link has a maximum transmission distance of 100m, enough to support almost all data center topology. You can also use the patch panels to manage copper cables flexibly, effectively improving the utilization of rack / cabinet space.
Low cost: when used for system wiring, super six network cable is usually cheaper than the same length of fiber cable . For example, the price of fast (FS) 1m PVC super six network cable is 13 yuan, while 1m PVC multi-mode OM1 fiber cable price is 16 yuan. In addition, copper cables do not consume power, have good heat dissipation effect, and maintenance costs are relatively low, so the use of 10 GBASE-T can greatly save the operating cost of the data center.
As can be seen from the above, the transmission of network data is quite important for our real life. So ,with the development of The Times, network transmission is also in rapid development, and Shenzhen HDV Phoelectron Technology co.,LTD. a company specializing in the sale of network equipment. In order to have good network equipment manufacturing qualification, company equipped with professional research and development team and quality team. This not only can guarantee the advanced nature of the product but also can guarantee the quality of the products. At present, our company mainly sells communication optical module, communication ONU, ONU optical cat, OLT equipment and Ethernet switch.Welcomed to know more from company.
