✦ Synopsis
into the future. At the same time, technology in both DWDM and optical networking were evolving at a very rapid rate. Alas, it was soon seen that, while customers had an insatiable need for bandwidth, the economics of providing their ever-escalating needs were not compelling. This led to a marked falloff in investment levels and the so-called bursting of the bubble. The most dramatic impact of the bubble burst was a very dramatic decline in investment in the core of the network.
So, where are we now? In the intervening years, the focus has shifted to metropolitan optical networks and the technology for getting optics ever closer to the end user. Bandwidth needs have continued to increase, albeit at a slower rate than during the bubble. The industry has also seen a stabilization of the market for equipment intended for the core, and even an uptick in new builds either to relieve exhaust on certain critical network segments or via the entry of a different breed of entrant/carrier doing nationwide
