Fios is Verizon’s fiber optic network, the latest in internet technology, that delivers the fastest and most stable internet. Fiber optic network is being laid out and is growing. At this point the network serves the North East and Mid Atlantic states of the US. Fiber-optic internet is connected via thin glass cables and transferred via light signals (hence the “optic”). This connection type provides for connections up to 1Gbps, making it lightning fast. For areas not served by Fios, Verizon offers high-speed DSL internet plans. DSL internet (which stands for digital subscriber line) is connected via telephone lines and delivers your internet by separating the data frequency from your calling frequency. Don’t’ expect Fios speeds on the DSL network.
