Right or wrong, the 10 Gb/s and 40 Gb/s fiber links already existed for SONET, so their application to Ethernet was logical. Beyond 40 Gb/s is new territory.
I would expect that when the 100 Gb/s serial Ethernet link is developed, any idea of 50 Gb/s will become obsolete. Seems to me that the only reason to consider serial 50 Gb/s is that it should be easier and quicker to develop than the serial 100, and that's about it. Otherwise, what's the point?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
