Centurylink services broadband Internet, TV, and phone service to consumers over two main network types: DSL and fiber-to-the-home (FTTH).
DSL "piggybacks" on Centurylink’s existing telephone lines to provide Internet.
DSL networks are usually more cost-effective compared to alternatives since they can use the same wires that carry calls.
If considering DSL plans, make sure to check speed tiers available in your area, as they can vary based on the distance between your house and the ISP’s local office.
Fiber, on the other hand, is widely considered the best consumer internet access.
Using a Fiber-to-the-Home implementation, Centurylink connects a fiber-optic line the full distance to your address, which leads to higher bandwidth.
That said, installing fiber optic is expensive for providers, with the result that fiber is not expanding quickly and usually comes with a higher monthly cost than DSL, cable, or fixed wireless.
