IEEE P802.3bj Task Force targets 100 Gigabit Ethernet for copper, backplanes

The IEEE has announced that the IEEE P802.3bj Task Force will work to develop specifications for 100-Gigabit Ethernet transmission over backplanes and short-reach copper assemblies. The new specifications will extend those already created for IEEE Std 802.3ba-2010.

“From the challenges of ever-increasing front-panel capacities to continuing advances in processors, high-performance computing, and server virtualization technologies, the ability of systems to meet spiraling bandwidth demands remains challenging,” said John D’Ambrosia, chair, IEEE P802.3bj Task Force and chief Ethernet evangelist, CTO Office, Dell. “By expanding on the solid foundational standards work already completed, IEEE P802.3bj will provide better options for system designers to minimize or eliminate the bandwidth bottlenecks facing end-users.”

The P802.3bj Task Force will focus on four-lane, 25-Gbps electrical signaling architectures that will support 100-Gbps Ethernet operation across backplanes up to 1 meter in length and copper cable operations up to at least 5 meters. The IEEE P802.3bj Task force also will seek maximum compliance and compatibility with other IEEE 802.3 installations.

The copper applications likely will include intra- and inter-rack connections via twinaxial copper cables. The new specifications are expected to benefit blade servers and data centers.

“The industry and users alike are looking for creative, forward-looking solutions that will allow them to leverage today’s technology innovations, such as 100-Gbps Ethernet,” said David Law, chair, IEEE 802.3 Working Group and distinguished engineer, HP Networking. “As the capabilities of 100-Gbps Ethernet are enhanced with IEEE P802.3bj, the resources, expertise and leadership that are the hallmarks of IEEE will support the continuing evolution of Ethernet to higher speeds and capabilities.”
