IEEE 802.3bz, the 2.5/5GBase-T standard, available for free download
As part of the IEEE Get program, the institute grants public access to view and download standards at no charge. The 802.3bz 2.5/5GBase-T standard is among those available.
Through the IEEE Get program, the Institute of Electrical and Electronics Engineers has made IEEE 802.3bq, the standard for 2.5GBase-T and 5GBase-T, available for free download. The standard’s official title is IEEE 802.3bz – 2016: IEEE Standard for Ethernet Amendment 7: Media Access Control Parameters, Physical Layers, and Management Parameters for 2.5 Gb/s and 5 Gb/s Operation, Types 2.5GBASE-T and 5GBASE-T.
Superseded and withdrawn standards or in printed book and CD-ROM format can also be purchased from IEEE along with drafts of standards, the institute also notes.
The 2.5/5GBase-T standard is one of several 802.3 standards now available for free download. Others include 802.3bq (25/40GBase-T), 802.3bp (1-Gbit over a single twisted pair), and 802.3by (optical 25-Gbit/sec).
