25GBASE-T call for interest


The following request for agenda time for a 25GBASE-T call for interest has been received from David Chalupsky. It will be discussed at the IEEE 802 LMSC November 2014 Plenary meeting in San Antonio, TX, USA.

If you have any questions please get in touch with either or directly.


The rapid progress of the 25 Gb/s Ethernet Study Group highlighted the broad market potential for 25 Gb/s Ethernet switch-to-server interconnect in a range of data center wiring architectures including within-rack, adjacent rack, middle-of-row, and end-of-row switching topologies. At the 10 Gb/s rate, the use of BASE-T for these applications is growing as an augment to fiber and direct-attach twinax copper. The IEEE P802.3bq 40GBASE-T Task Force has been addressing switch-to-server interconnect for these topologies at a 40 Gb/s rate. At this time, there is no path for data centers to utilize cost-effective and backwards compatible BASE-T technology for 25 Gb/s Ethernet. This Call For Interest is a request for the formation of a study group to explore 25 Gb/s BASE-T Ethernet and potentially extending the work of the IEEE P802.3bq Task Force to include it.


The call for interest will take place during the IEEE 802.3 Opening Plenary on the afternoon of Monday 3rd November. A call for interest consensus building meeting has been scheduled to occur from 19:30 to 21:00 on the evening of Tuesday 4th November. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 6th November.
