Frontier offers DSL and fiber optic services but does not provide coaxial cable internet. The company's primary focus lies in expanding its fiber optic network across its extensive coverage areas. DSL serves as an alternative where fiber optic infrastructure is not yet available. Fiber optic technology stands out as the superior choice for speed and reliability, albeit requiring a more complex infrastructure compared to DSL. While DSL operates on existing telephone lines, fiber optic installation necessitates the laying of new cables containing glass tubing underground. Challenges arise particularly in rugged terrains such as mountains or rocky areas, where burying fiber optic cables becomes more difficult. The cost of deploying fiber optic infrastructure is carefully considered, taking into account factors such as population density in the area. Providers weigh this investment against the potential for acquiring a significant amount of new business to recoup their expenses.
