Yes, would be nice to know the name of this guy. Would his initials be "B.U."? Did this start-up name begin with "X" by any chance? I too live in Allen TX and have designed backplanes, but not for bit rates as high as you describe. Would be interesting to know the card connectors, and whether the diff pairs were edge or broadside coupled. Maybe this mystery guru could write an article...

Well, way back in the dim dark past (2000-2001, before the Great Telecom Meltdown of 2002), a start-up in Allen, TX that I worked for was building a really high-speed metro switch. The BP had a bunch of LVDS buses that were running @ 2.5Gb/s; however this was CO stuff, and had to be in-service upgradeable to 20 years! So our target was to be sure we could handle 10Gb/s error-free. The guy assigned to it was very conservative, and built us a BP with inner layers using exotic materials (GoreTex?). We didn't have any silicon to really test it with beyond the then-current 2.5 Gb/s, so we contacted a major semi manufacturer who we knew was working on some really far-out tech. We shipped them a BP along with some connectorized paddle boards. They checked it out for us with experimental semis @ 10Gb/s, NO ERRORS. Then for kicks they started running up the clock to the limit. Somewhere near 40Gb/s they started getting some errors! That BP turned out to be AWESOME, but overkill; as I recall we finally got it down to 14 layers, and a volume production cost (with connectors) over $3K! If anybody wants the name of the guy who did it, let me know....

Pretty awkward non-sequitur with the hope & change thing but I get your drift about predicting the future!

Good luck hearding those cats! It's amazing to think of 100G at the board level.
