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.
Suffolk (/ˈsʌfək/) is an East Anglian county of historic origin in England. It has borders with Norfolk to the north, Cambridgeshire to the west and Essex to the south. The North Sea lies to the east. The county town is Ipswich; other important towns include Lowestoft, Bury St Edmunds, Newmarket, and Felixstowe, one of the largest container ports in Europe.
The county is low-lying but it has quite a few hills (especially more to the west), and has largely arable land with the wetlands of the Broads in the north. The Suffolk Coast and Heaths are an Area of Outstanding Natural Beauty.
