CHAPTER 7 All-Optical Networks Chapter 7 Let's take a critical look at the evolving optical technologies that may see carrier deployment in the next two to five years. They include all-optical networks without real-time user signaling control, which are often called Optical Transport Networks (OTNs), and all-optical networks equipped with real-time signaling control, which are often called Intelligent Optical Networks (IONs). Unsurprisingly, carriers lean toward OTNs, whereas tech- nology vendors favor IONs. In part, th
