IEEE Approves IEEE 802.3bz Standard for 2.5 Gbps and 5 Gbps over Existing Cabling

On 10 November, IEEE officially published IEEE 802.3bz-2016 – Standard for Ethernet Amendment: Media Access Control Parameters, Physical Layers and Management Parameters for 2.5 Gbps and 5 Gbps Operation.

The standard revision demonstrates a quick response to meet growing capacity demands on more than the 70 billion meters of Category 5e and Category 6 cabling that is reportedly installed around the world.

Completed in 18 months, IEEE 802.3bz-2016 supports the growing need for Ethernet connectivity over structured twisted pair wiring beyond the 1 Gbps capability provided by the IEEE 802.3ab standard (1000BASE-T), which is considered by many to be the most successful Ethernet physical layer standard. The new standard defines Ethernet Media Access Control (MAC) parameters, physical layer specifications, and management objects for the transfer of Ethernet format frames at 2.5 Gbps and 5 Gbps, so that enterprise interconnect solutions over structured Category 5e or better twisted pair cabling can support modern wireless access points without compromise.

The development team for IEEE 802.3bz-2016 has responded quickly to a market demand that represents a huge cost savings for enterprises by allowing them to improve their network performance over existing cablingDavid Chalupsky, chair, IEEE 802.3bz 2.5G/5GBASE-T Task Force.
