Fibre Network

​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]

​Norwich (/ˈnɒrɪdʒ, -ɪtʃ/ (About this soundlisten)) is a city in Norfolk, England, situated on the River Wensum in East Anglia, about 100 miles (160 km) north-east of London. A city since 1094, Norwich is the county town of Norfolk and unofficially seen as East Anglia's capital. From the late Middle Ages until the Industrial Revolution, Norwich was the largest city in England after London and one of the most important.[3] The present-day population of the city is about 142,000.
