Fibre
Fibre-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light[1] through an optical fibre. The light is a form of carrier wave that is modulated to carry information.[2] Fibre is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required.[3] This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.[4]
Optical fibre is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth–distance product of over 100 petabit × kilometers per second using fibre-optic communication.[5]
Staffordshire (/ˈstæfərdˌʃɪər, -ʃər/;[2] postal abbreviation Staffs.) is a landlocked county in the West Midlands of England. It borders Cheshire to the northwest, Derbyshire and Leicestershire to the east, Warwickshire to the southeast, West Midlands and Worcestershire to the south, and Shropshire to the west.
The largest settlement in Staffordshire is Stoke-on-Trent, which is administered as an independent unitary authority, separately from the rest of the county. Lichfield, a smaller settlement, is a cathedral city. Other major settlements include Stafford, Burton upon Trent, Cannock, Newcastle-under-Lyme, Rugeley, Leek, and Tamworth.
Smaller towns include Stone, Cheadle, Uttoxeter, Burntwood/Chasetown, Eccleshall, Biddulph, Penkridge and the large villages of Wombourne, Kinver, Tutbury, Alrewas, Barton-under-Needwood, Stretton and Abbots Bromley. Cannock Chase AONB is within the county as well as parts of the National Forest and the Peak District national park.
Wolverhampton, Walsall, West Bromwich and Smethwick are within the historic county boundaries of Staffordshire, but since 1974 have been part of the West Midlands county.
Apart from Stoke-on-Trent, Staffordshire is divided into the districts of Cannock Chase, East Staffordshire, Lichfield, Newcastle-under-Lyme, South Staffordshire, Stafford, Staffordshire Moorlands, and Tamworth.
