Who Has Fiber Internet? A Guide to Providers
Many of the fastest Internet plans come from fiber-optic networks.
Fiber-optic Internet, especially Fiber to the Home (FTTH), delivers consistent broadband access. It’s a technology many providers have turned to for the crux of their networks. Fiber provides network reliability and speed potential. Fiber-optic Internet introduced the first gigabit speeds for residential use.
Hair-thin, flexible glass strands make up a fiber-optic network. Cables of these strands make up a delivery method that can provide speeds faster than that of cable or DSL. Fiber's efficiency allows for more distance covered than cable or DSL without signal degradation.
At today’s speeds, most tasks, even the most data-rich,

Data moves at higher frequencies than it does in copper systems, which gives fiber more data capacity. At basic plans, users can stream movies or music as others game online or videoconference.
A resistance to electromagnetic interference gives fiber an edge over systems of metal cables. Fewer factors can interrupt or compromise service on a fiber-optic network than on one built on copper wires.
Does Comcast have fiber-optic Internet?
Yes, but it’s not FTTH. Comcasts advertises 2Gbps speeds on a network with fiber optics until the final mile. Comcast offers another gigabit Internet service over cable lines. Comcast, founded in 1963, upgraded its cable network to offer speeds of 1,000Mbps.
Comcast’s business FTTN network covers 39 states and the District of Columbia. Comcast business fiber Internet covers large cities, concentrated on the east coast. It offers a non-fiber product called Metro Ethernet to some of its fiber markets. It's also available in a few second-tier-population cities.
Customers must live within a third of a mile of the Comcast fiber network to get Gigabit Pro. Comcast's website spells out other conditions of
