Turning the speed dial
6/28/2012   3 comments
With all the standards activity focused on making all sorts of electrical interfaces run faster and use less power, cost less and enable higher density, is it time to turn the speed dial up on the process?

It is a myth that the IEEE makes decisions regarding standards, and the importance of opportunities for the industry to gather and drive toward consensus cannot be overstated.

A quick run-down on a number of the activities in play in the Ethernet world.
Timing is everything…
12/1/2010   Post a comment
A couple of months ago, I blogged about a new 100GbE backplane project on the horizon that might also be leveraged for a narrower cable solution than the current 100GBASE-CR10 option that requires 10 differential pairs in each direction. At the November IEEE Plenary in Dallas, the first steps were taken as a study group was formed to start examining this problem.

It appears that the 100 Gigabit Ethernet family will continue to be a source of technological drama for the industry, with at least two efforts on the IEEE 802.3 horizon likely to provoke industry debate.
Cut down a tree with a herring?
