The broadest broadband, of course, is optical fiber, the only medium capable of moving data at multigigabit-per-second speeds. It's fiber that will ferry us into a future of thousands of television channels, videoconference telephony, movies on demand, distance learning, telemedicine, and a digital record of every sight and sound around us.
We've known this for two decades. Yet only rarely is an existing residential connection being refurbished with fiber. That will soon change—in fact, the pace of fiber installation is expected to pick up dramatically in the next few years.
This past summer the three largest U.S. telecommunications providers, Verizon, SBC, and BellSouth, agreed on a common set of standards for residential fiber-optic networks. That congruity is expected to lower costs and unleash a tidal wave of spending—Verizon alone reportedly has plans to embark on a 10- to 15-year US $20 billion to $40 billion upgrade of its fiber-to-the-premises networks.
