Fiber to the x (FTTX; also spelled "fibre") or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
FTTX is a generalization for several configurations of fiber deployment, arranged into two groups: FTTP/FTTH/FTTB (Fiber laid all the way to the premises/home/building) and FTTC/N (fiber laid to the cabinet/node, with copper wires completing the connection).
Residential areas already served by balanced pair distribution plant call for a trade-off between cost and capacity. The closer the fiber head, the higher the cost of construction and the higher the channel capacity. In places not served by metallic facilities, little cost is saved by not running fiber to the home.
Fiber to the x is the key method used to drive next-generation access (NGA), which describes a significant upgrade to the broadband available by making a step change in speed and quality of the service. This is typically thought of as asymmetrical with a download speed of 24 Mbit/s plus and a fast upload speed. Ofcom have defined super-fast broadband as "broadband products that provide a maximum download speed that is greater than 24 Mbit/s - this threshold is commonly considered to be the maximum speed that can be supported on current generation (copper-based) networks."
A similar network called a hybrid fiber-coaxial (HFC) network is used by cable television operators but is usually not synonymous with "fiber In the loop", although similar advanced services are provided by the HFC networks. Fixed wireless and mobile wireless technologies such as Wi-Fi, WiMAX and 3GPP Long Term Evolution (LTE) are an alternative for providing Internet access.
Burton upon Trent, also known as Burton-on-Trent or simply Burton, is a market town in Staffordshire, England, close to the border with Derbyshire. In 2011, it had a population of 72,299. The demonym for residents of the town is 'Burtonian'. Burton is 11 miles (18 km) southwest of Derby, 27 miles (43 km) northwest of Leicester, 28 miles (45 km) west-southwest of Nottingham and 20 miles (32 km) south of the southern entrance to the Peak District National Park.
Burton is known for brewing. The town originally grew up around Burton Abbey. Burton Bridge was also the site of two battles, in 1322 when Edward II defeated the rebel Earl of Lancaster and 1643 when royalists captured the town during the First English Civil War. William Lord Paget and his descendants were responsible for extending the manor house within the abbey grounds and facilitating the extension of the River Trent Navigation to Burton. Burton grew into a busy market town by the early modern period.
The town is served by Burton-on-Trent railway station. The town was also the start and terminus of the now defunct South Staffordshire Line which linked it to Lichfield, Walsall, Dudley and Stourbridge.
