Do you know that 10-Gigabit Ethernet was introduced back in 2006, and was created mainly for file servers of small companies, and even after a decade and a half, it still remains a curiosity for many consumers in the small business environment. The reason is simple to the point of banality: there were no speeds for which you can invest in 10-Gigabit switches and expensive cable infrastructure. The concept of using personal laptops, wireless MFPs, smartphones and monoblocks required the development of wireless networks, and Gigabit wire, as a rule, was enough for everyone.
Progress did not stand still, and in order to somehow move things from the dead end, in 2015, network equipment manufacturers proposed intermediate standards Nbase-T (802.3 bz) with speeds of 2.5 Gbit/s and 5 Gbit/s. They solved the main problem that hindered the spread of 10-Gigabit networks in small businesses: they allowed the use of CAT-5 cable, that is, a conventional twisted pair with the same connectors as for 1-Gigabit networks. In fact, manufacturers offered to use existing cables for new fast networks, and from about 2015-2017, there were also available network controllers on Aquantia and Broadcom chips with support for 10GBase-T and NBase-T, which were used in top-end computers for enthusiasts and in NAS-s. But, again, these decisions did not cause any excitement.
|Standard||Number of bits per 1 cycle||Requirements for the type of cable to connect to a distance of up to 50 meters||Cable type requirements for connecting up to 100 meters||Bandwidth, MHz|
The thing is that by the time the Nbase-T equipment went on sale, those users who were interested in high LAN speed had long since switched to 10 Gbit/s using optical or copper cable, and to include 2500BASE-X networks in projects, a driver was needed, and it appeared only at the beginning of 2020.
This driver is the wireless access points of the 802.11 ac and 802.11 ax standards, whose total bandwidth has long exceeded 1 Gbit / s and is limited to the possibility of a wired connection. Today, the availability of fast modern wireless access to the network has already become mandatory not only for commercial, but also for government facilities: in offices, hospitals, trains, MFC, conference rooms and pleasure boats, where yesterday they put access points 802.11 ac, today they are changing to 802.11 ax. And here the 2500BASE-X standard acts as an ideal cure for low speed: you do not need to move the cable and crimp chips: just change the access point and switch - and get an interconnect speed of 2.5 Gbit/s under the same conditions. A good competitive advantage, isn’t it?
