Other service providers often use fiber optics in the network backbone and existing copper or infrastructure for residential users. Service began in 2005, and coverage areas expanded through 2010, although some areas do not have service or cannot receive TV and phone service because of franchise agreements.

Technical details


As described in 2007, Verizon FiOS services are delivered over a fiber-to-the-premises network using passive optical network
Passive optical network
A passive optical network is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 16-128.
