Thursday, October 9, 2014 at 1:55PM The chairman of the Ethernet Alliance talks to Gazettabyte about the many ways Ethernet is evolving due to industry requirements.
"We are witnessing the evolution of Ethernet in ways that many of us never planned because there are markets that are demanding different things from it."
Wednesday, September 25, 2013 at 1:52PM Eleven companies have been participating in nine demonstrations at the European Conference and Exhibition on Optical Communication (ECOC2013) being held in London this week.
The Open Internetworking Forum (OIF) has demonstrated its specified 25 and 28 Gigabit-per-second (Gbps) electrical interfaces working across various vendors' 100 Gigabit modules and ICs.
"The infrastructure over the backplane is maturing to the point of 25 Gig; you don't need special optical backplanes" John Monson, Mosys
"The ecosystem is maturing," says John Monson, vice president of marketing at Mosys, one of the 11 firms participating in the demonstrations. "The demos are not just showing the electrical OIF interfaces but their functioning between multiple vendors, with optical standards running across them at 100 Gig."
The demonstrations - using the CFP2, QSFP and CPAK optical modules and the 28Gbps CEI-28G-VSR module-to-chip electrical interface - set the stage for higher density 400 and 800 Gigabit line cards, says Monson. The CEI-28G-VSR is specified for up to 10dB of signal loss, equating to some 4 to 6 inches of trace on a high-quality material printed circuit board.

Relative traffic increase normalised to 2010 Source: IEEE
Optical component and system vendors will be increasingly challenged to meet the expected growth in bandwidth demand.
According to a recent comprehensive study by the IEEE (The IEEE 802.3 Industry Connections Ethernet Bandwidth Assessment report), bandwidth requirements are set to grow 10x by 2015 compared to demand in 2010, and a further 10x between 2015 and 2020. Meanwhile, the technical challenges are growing for the vendors developing optical transmission equipment and short-reach high-speed optical interfaces.

The IEEE has begun work to develop the next-speed Ethernet standard beyond 100 Gigabit to address significant predicted growth in bandwidth demand.
The standards body has set up the IEEE 802.3 Industry Connections Higher Speed Ethernet Consensus group, chaired by John D’Ambrosia, who previously chaired the 40 and 100 Gigabit IEEE P802.3ba Ethernet standards ratified in June 2010. "I guess I’m a glutton for punishment,” quips D'Ambrosia.
The Higher Speed Ethernet standard could be completed by early 2017.
Wednesday, November 17, 2010 at 2:38PM Xilinx has detailed its latest 28nm CMOS Virtex-7 FPGA family that will support 400 Gigabit Ethernet on a single device. The Virtex-7HT completes the Virtex-7, joining the Virtex-7T and Virtex-7XT product families announced in June.
A single FPGA will support 400 Gigabit Ethernet duplex traffic. The FPGA can also support 4x100Gig MACs and 4x150Gbps Interlaken interfaces. Source: Xilinx
Why is it important?
Xilinx says its switch and router customers are more than doubling the traffic capacity of their platforms every three years. “They are looking for silicon that will support a doubling of capacity within the same form-factor and the same power budget,” says Giles Peckham, EMEA marketing director at Xilinx.
