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.
Redditch is a town, and local government district in north-east Worcestershire, England, approximately 15 miles (24 km) south of Birmingham. The district has a population of 85,000 as of 2019. In the 19th century it became the international centre for the needle and fishing tackle industry. At one point 90% of the world's needles were manufactured in the town and its neighbourhoods. In the 1960s it became a model for modern new town planning.
