New IEEE 802.3™ group to study standardizing single-lane 25 Gb/s
Ethernet interconnect technologies to provide greater server bandwidth
to cloud-scale data centers
PISCATAWAY, N.J.--(BUSINESS WIRE)--
IEEE, the world’s largest professional organization dedicated to
advancing technology for humanity, today announced the formation of the
IEEE 802.3™ 25 Gb/s Ethernet Study Group to explore the market
opportunities and needs for a single-lane 25 Gb/s speed for server
interconnects for Ethernet.
Companies building data centers desire IEEE 802.3 standards-based
interoperable solutions that will enable and extend a multi-vendor
eco-system providing a cost optimized solution. The reuse of serial lane
25 Gb/s signaling technology—developed to support 100 Gb/s
Ethernet—enables cost optimized deployments in newly constructed data
centers. This is especially true for the companies that will need server
interconnects that support 10 Gb/s Ethernet and beyond.
“The application of single-lane 25 Gb/s signaling technologies provides
Ethernet with a solution set that can be reused by those companies
building the data centers of tomorrow. The new study group expects to
lay the groundwork for a new Media Access Control (MAC) rate that will
enable cost-optimized single-lane solutions that will increase network
deployment efficiency,” said Mark Nowell, chair of the IEEE 802.3 25
Gb/s Ethernet Study Group and senior director, Cisco Systems. “The heavy
lifting in developing and standardizing 25 Gb/s signaling technologies
has been done as part of the development of 100 Gb/s Ethernet. These
technologies can be reused to enable a single-lane 25 Gb/s Ethernet
solution set for server interconnects for these future data centers.”
The ratification of IEEE 802.3ba™-2010 “Standard for Information
Technology—Local and Metropolitan Networks for 40 Gb/s and 100 Gb/s
Operation” introduced 4 x 25 Gb/s signaling as a fundamental building
block for 100 Gb/s Ethernet. Since then, the IEEE 802.3 Ethernet Working
Group has expanded the use of this basic rate of signaling technology.
IEEE 802.3bj™-2014 “Standard for Physical Layer Specifications and
Management Parameters for 100 Gb/s Operation Over Backplanes and Copper
Cables”, based on 4 x 25 Gb/s electrical signaling, defines 100 Gb/s
Ethernet Operation over backplanes and copper twin-axial cables. While
currently in progress, the IEEE P802.3bm™ 40 Gb/s and 100 Gb/s Fiber
Optic Task Force is drafting a standard that will define 4 x 25 Gb/s
operation for signal traces for chip-to-chip and chip-to-module
applications, as well as for 25 Gb/s operation over four parallel
“Manufacturers and suppliers require standards-based networking to
enable and extend the industry’s multi-vendor eco-system,” said David
Law, chair of the IEEE 802.3 Ethernet Working Group and distinguished
engineer with HP Networking. “This study group will provide the
opportunity to explore the possible development of a single-lane 25 Gb/s
Ethernet standard supporting those application spaces needing
cost-optimized performance beyond 10 Gb/s Ethernet for large scale
