thank you Janine, makes sense...I presume 25G links use FECso the real number is higher than 25G, right?

That's exactly right @Krisi, 4x25

Not sure...why 25 Gb/s?...such a strange number...I haven't followed this for years but I would think 40 Gb/s was more natural...or is it 4x25=100?

Re: 25G Ethernet on Tap at IEEE

It seems like many flavours of datacenter ethernet are settling down! Couple of years ago, there was 10Gbps x 4 and 10Gbps x 10 for 40Gig and 100Gig ethernet, some what influenced by the legacy InfiniBand camp. I am glad to see 25Gbps getting the approval of the majority.

We did have healthy discussions around 25/28gig SerDes couple of years ago after OIF / CEI standard for 25G class designs was approved:


Here is another link to a presentation on signal integrity challenges for 100Gig ethernet that considers the 25/28Gig lanes as one of the options (focus mostly on the backplane).

There are certainly specific issues, complexities, and challenges of moving to 25G or higher, and I'm glad to see this decision by IEEE. For futher reading/info: Steve Tarnovich at EDN posted an article on 100GbE recently, and this is a major topic that we deal with at DesignCon.

Overview: Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
