Techwarelabs Community - Dark Fiber Creates Optic Gloom

Here is an intersting article I found on TechTV about Optical Networks:

In the last two years, telecom and networking companies spent hundreds of billions of dollars building global fiber-optic networks. An estimated 100 million miles of optical fiber was laid worldwide -- more than enough to connect the Earth to the Sun.
Driving this frenzied expansion was the rapidly growing Internet, the proliferation of high-bandwidth applications such as streaming video, and corporations' increasing hunger for data.
But the sheer number of fiber networks, combined with a slowdown in IT spending, has left millions of miles of "dark fiber": optical networks that lie unused.
