Frontier Fiber

Frontier Fiber (formerly known as Frontier FiOS or FiOS from Frontier) is a bundled Internet access, telephone, and (until 2021) television service that operates over a fiber-optic communications network. Service is offered in some areas of the United States by Frontier Communications in areas built out and formerly served by Verizon, using the same infrastructure as its Fios service. Other service providers often use fiber optics in the network backbone and existing copper or coax infrastructure for residential users. Frontier's service began in 2009 with the acquisition of portions of Verizon's network, and networked areas expanded through 2015 through similar acquisitions, although some areas do not have service or cannot receive TV and phone service because of franchise agreements.
