re: 100-GigE, 40-GigE Live in PeacePity that the IEEE 802 seems to be becoming more and more incapable of making hard decisions.
In all the working groups (.3, .11, .15, .16, .20, etc.) all we ever see is either "let's compromise and put in both as options" or "I have the numbers to block this and I don't care how long I will block it for".
With the first approach you have death by options and a whole new business model based on adding options in 802 and then creating fora to clean up the mess (look at 10GEA, RPRA, WiFiA and WiMAX forum). With the second approach you have the whole mess of 802.20 and the UWB work in 802.15.
Is it time we simply walked away and went to some other place that can actually make real compromise decisions?
re: 100-GigE, 40-GigE Live in PeaceActually I have read a few papers on MIMO over multimode that might just work at very high rates and longish distances. Not sure about 100 km at 100 Gbit/s but it could be fun! Cost effective is of course another issue since MIMO at 100 Gbit/s would be lots of processing, not to mention the 4 or 8 parallel sources and detectors along with the need to launch each source into a particular mode down the fibre. Time to move this thread over to Unstrung where the MIMO people read!

Real cost/problems is in not launching parallel sources into fiber (Not that difficult). I believe that for 100Gb to be a cost effective solution (For long distances), we need real good work in Photonic intergration where many Photonic devices can be intergrated.
