IEEE P802.3ba, 40Gb/s and 100b/s

 

This subcommittee has developed baseline proposals accepted by the IEEE 802.3ba Task Force for increased performance levels for data center and long-haul networking applications. The project includes backplanes, short-reach copper cabling, medium reach multi-strand fiber, and long-reach single-mode fiber physical layers.

While the first generation of devices supporting 100 Gigabit per second (Gb/s) will utilize a 10 lane by 10 Gb/s signaling rate, future power and size reduction requirements will drive the need for a faster, narrower interface. Noting these future needs, the Optical Internetworking Forum has initiated development of standards for the next generation of electrical signaling for long reach and short reach applications.

This paper provides an overview of the CEI-28G project, which defines electrical specifications for 28 Gbaud/s signaling for next generation chip-to-chip and chip-to-module applications that support transmission of 100 Gb/s data rates, such as 100 Gigabit Ethernet and OTU4.

This paper will address the challenges of scaling packet networks from the current state-of-the-art, 10 Gbps limited packet-aware, to next generation 100 Gbps all packet-aware, any-to-any networks. The areas covered will include optical/electrical interfaces, interface adaptation, data plane processing, control plane processing, as well as switching, system power and printed circuit board requirements. These challenges apply to platforms that aggregate lower speed interfaces, up to 100 Gbps, as well as platforms with pure 100 Gbps interfaces.

 

The IEEE P802.3ba 40 Gb/s and 100 Gb/s Ethernet Task Force has been working on the development of 40 Gigabit Ethernet and 100 Gigabit Ethernet. In October 2008, the Task Force took a major step forward, as it generated Draft 1.0 of the amendment to the IEEE Std 802.3TM- 2008 Ethernet standard. The Task Force has developed a single architecture capable of supporting both 40 Gigabit Ethernet and 100 Gigabit Ethernet, while producing physical layer specifications for communication across backplanes, copper cabling, multi-mode gigabit per second, and single-mode gigabit per second. This white paper provides an overview of the 40 Gigabit Ethernet and 100 Gigabit Ethernet project and the underlying technologies.

Service providers have become increasingly challenged to accommodate customer requests for services; 100GbE is the indentified solution for providing the next generation of internet connectivity to continue to fuel the delivery of new services and content to the consumer and business customers.
