Road to 100Gb/sec…Innovation Required! (Part 3 of 3)

Physical Layer Innovation: Silicon Photonics So in two previous posts, I discussed the innovations required at the transport, network, and link layer of the communications protocol stack to take advantage of 100Gb/s networks . Let’s now talk about the physical layer. A 100Gb/sec signaling rate implies a 10ps symbol period. Frankly, this is just not […]

Silicon Photonics: Using the Right Technology for Data Center Applications

At DesignCon last week, I followed a speaker who ended his presentation with a quote from Mark Twain, “the reports of my death have been greatly exaggerated!”  The speaker was talking about copper cabling on a panel entitled, “Optical Systems Technologies and Integration.”  He showed some nice charts on high speed signaling over copper, making […]
