IEEE 802.3bz: data transfer standard on 2.5 and 5 Gb / s cables Cat 5e and Cat 6

Most home wired network data transfer rate of 1 Gbit / s, Gigabit Ethernet infrastructure reliably does its job. As for the cable, the most popular are Cat 5e or Cat 6. Alliance NBASE-T approved the new standard IEEE 802.3bz, providing significantly faster transfer rates for similar cables than 1 Gbit / s.

IEEE 802.3bz: Features

In IEEE 802.3bz need arose for two reasons. Next, after the standard 1 Gb / s Ethernet – is the 10GBASE-T 10 Gigabit / s, but the Cat 6A cable is required for him or a higher category. In the case of IEEE 802.3bz can use the existing infrastructure network cables. Moreover, 10GBASE-T network equipment does not support power supply via Power over Ethernet (PoE) technology. When you deploy Wi-Fi networks with significant coverage, for example, a very popular access point for which power is supplied power from PoE. And in the case of 10GBASE-T this is not possible.

IEEE 802.3bz provides support for IEEE 802.3af-2003 PoE standard with a capacity of up to 15.4 W (12.95 W is guaranteed) and PoE + according to IEEE 802.3at-2009, to which the power supply power to 25.5 watts. Therefore NBASE-T standard IEEE 802.3bz equipment will be interesting to providers who will be able to connect wireless access points for a faster connection to the 2.5 or 5 Gb / s.

IEEE 802.3bz: Specifications

Specifications for the following: IEEE P802.3bz standard for all functions (Media Access Control Parameters, Physical Layers, Management Parameters) at a speed of 2.5 Gb / s requires a Cat 5e cable. The rate of 5Gb / s Cat 5e cable can not always required Cat cable 6. The cable length is 100 m per segment.

Of course, in addition to a compatible cable, you should use hardware that supports the new standard. The following year, the market should start to appear in large new devices that support the new standard. And Ethernet 2.5 or 5 Gbit / s will become an interesting alternative to the current standard of 1 Gbit / s. Of course, nothing prevents deploying 10GBASE-T equipment on 10 Gbit / s at home or in the corporate segment, but here the equipment and cables are much more expensive. Netgear has introduced the M4200 10MG PoE + Switch with Ethernet at speeds of 2.5 and 5 Gb / s.
