Accepted to IEEE 802.3 bz — standardized Ethernet speed of 2.5 Gbps and 5 Gbps
The Ethernet Alliance organization, engaged in the development and promotion of Ethernet technology, announced the ratification of IEEE 802.3 bz. This specification supplements the standard Ethernet by adding to it the data transfer speed of 2.5 Gbps and 5 Gbps.
According to the developers of additions to the standard, a need was stimulated by the advent of wireless networking specification IEEE 802.11 ac, against which the speed of 1 Gbit/s, provide a wired connection 1000BASE-T became insufficient. At the same time, the developers realized that the capacity of approximately 70 billion meters of cabling Cat5e / Cat6, laid in the world, is not fully used. Specification IEEE 802.to elegantly bridge the gap between the existing infrastructure of Gigabit Ethernet and higher-speed solutions without extra costs.
