Centurylink services Internet, TV, and telephone service to customers using two main network types: DSL and fiber.
DSL leverages Centurylink’s already-installed telephone infrastructure to deliver Internet services.
DSL networks are widely available and usually more cost-effective than alternatives since they can use the same wires that carry calls.
When you are evaluating DSL plans, verify speed tiers available locally, as they can change depending on the distance to the provider’s local office.
Fiber-to-the-home, on the contrary, is described as the best internet service.
In a FTTH setup, CenturyLink connects a fiber connection the full distance to customer residences, leading to better overall performance.
However, fiber is expensive — such that this type of service is not widely available.
