Verizon FiOS Chapter 18 project 18-3

What Is Verizon FiOS? Verizon FiOS is a bundled Internet access, telephone, and television service which operates over a fiber-optic communications network. It is offered in some areas of the United States by Verizon Communications and Frontier Communications. Verizon was one of the first major U.S. carriers to offer fiber to the home, and received positive ratings from Consumer Reports among cable television and Internet service providers. 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. Internet access FiOS offers several service tiers that are available individually, but are offered at significant discounts when combined in a bundle. Although all current tiers are available nationwide, price varies between markets and some legacy tiers are available only in select markets. The tiers are distinguished by data transmission speed measured in Mbit/s downstream and upstream. Six different offerings are available. What downstream and upstream speeds can FiOS support? 1310 nm wavelength for upstream data at 155 Mbit/s (1.2 Gbit/s with GPON) 1490 nm wavelength for downstream data at 622 Mbit/s (2.4 Gbit/s with GPON) 1550 nm wavelength for QAM cable television with 870 MHz of bandwidth. When using FiOS, does your telephone voice communication share the fiber-optic cable with internet data? Verizon offers regular telephone service as well as voice over IP over FiOS. The common model optical network terminals have two or four phone jacks. What does Verizon say about FiOS cabling used for television? Verizon's broadcast video service is not IPTV (Internet Protocol television), unlike AT&T's U-verse product. However, video on demand content and interactive features, such as widgets and programing guide data, are delivered using IPTV-based technology. The majority of content is provided over a standard broadcast video signal that carries digital QAM content up to 870 MHz. This broadcast content originates from a Super Head-End, which sends the signal to a Video Hub Office for distribution to FiOS TV customers. From the Optical Network Terminal (ONT) at the subscriber premise, the RF video is delivered with a coaxial connection to typically a FiOS set-top box that handles both RF and IPTV video. Interactive services such as VOD and widgets are delivered by IP and are only accessible through use of a FiOS set-top box and a Verizon-supplied router. The router supports multimedia (MOCA) and provides the set-top boxes with programming guides and all SD channels, but high definition content (beyond local HD channels which are in clear QAM) requires HD equipment like a FiOS HD set-top box/DVR or a CableCARD-supporting device, such as TiVo. In 2008, Verizon ceased carrying analog television signals in parallel with digital channels, meaning televisions without a QAM tuner or a set-top digital adapter received no signal Is FiOS available in your area? Yes.
