How fiber optics communications system works
The process of communicating using fiber-optics involves the following basic steps: creating the optical signal involving the use of a transmitter, [8] usually from an electrical signal relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak receiving the optical signal Meer weergeven Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. … Meer weergeven First developed in the 1970s, fiber-optics have revolutionized the telecommunications industry and have played a … Meer weergeven In 1880 Alexander Graham Bell and his assistant Charles Sumner Tainter created a very early precursor to fiber-optic communications, the Photophone, at Bell's newly established Volta Laboratory in Washington, D.C. Bell considered it his most … Meer weergeven Bandwidth–distance product Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of MHz·km. This value is a product … Meer weergeven Optical fiber is used by telecommunications companies to transmit telephone signals, Internet communication and cable television signals. It is also used in other industries, including medical, defense, government, industrial and commercial. In addition to … Meer weergeven Modern fiber-optic communication systems generally include optical transmitters that convert electrical signals into optical signals, optical fiber cables to carry the … Meer weergeven The choice between optical fiber and electrical (or copper) transmission for a particular system is made based on a number of trade-offs. Optical fiber is generally … Meer weergeven WebThe optical communication system is based on laser diodes as transmitters and photodetector as receiver.
