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.
