Fibre-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fibre. The light is a form of carrier wave that is modulated to carry information. Fibre is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.
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.
Nottinghamshire (pronounced /ˈnɒtɪŋəmʃər, -ʃɪər/; abbreviated Notts.) is a county in the East Midlands region of England, bordering South Yorkshire to the north-west, Lincolnshire to the east, Leicestershire to the south, and Derbyshire to the west. The traditional county town is Nottingham, though the county council is based at County Hall in West Bridgford in the borough of Rushcliffe, at a site facing Nottingham over the River Trent.
The districts of Nottinghamshire are Ashfield, Bassetlaw, Broxtowe, Gedling, Mansfield, Newark and Sherwood, and Rushcliffe. The City of Nottingham was administratively part of Nottinghamshire between 1974 and 1998, but is now a unitary authority, remaining part of Nottinghamshire for ceremonial purposes.
In 2017, the county was estimated to have a population of 785,800. Over half of the population of the county live in the Greater Nottingham conurbation (which continues into Derbyshire). The conurbation has a population of about 650,000, though less than half live within the city boundaries.
