While the “backbone” of the internet (yes, the whole internet) is made up of fiber optics (microscopic glass strands that transmit data as pulses of light), most “last mile” connections that go directly to homes and businesses are still made up of old copper phone lines and coaxial TV cables.
Fiber-to-premises internet is an expensive but slowly growing infrastructure; currently, less than half of the US is covered by fiber. If your neighborhood isn’t hooked up yet, internet providers like Verizon Fios are probably planning fiber expansion in your area—but it won’t happen overnight.
These states currently have Verizon Fios fiber internet:
- New Jersey
- New York
- Rhode Island
- Washington, DC
