An Introduction To Fiber Optics Technology Essay example -- Technology

An Introduction to Fiber Optics TechnologyThroughout time, speed and dexterity in the telecommunications industry has progressed at a rapid pace ascribable to fiber optical technology. In 1979, AT&T revolutionized the telecommunications industry by producing a medium for data transmission which used light, called fiber optic cable. This medium created a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits onto one fiber (Cole, 2000). However, this guile was only the beginning of a great addition to telecommunications, one that would commute the industry forever.Even though AT&T introduced fiber optic technology in 1979, they werent the first company to think of such a creative vagary. The concept of exchanging data by the use of light was model of by Alexander Graham doorbell in the late 1800s. chime always thought of possibilities that pulses of light could post voice signals, but Bell never had a dependable light source to test the idea (Cheo, 1990). In 1880, Bell patented a phone utilize optical transmission called the Photophone. Bells invention failed because it used air as the medium to transmit light, rather than the glass fibers that are used today. Copper wire was plainly more reliable than Bells invention at the time, leading to the failure of his Photophone (Hecht, 1999).Expanding on Bells idea, English scientist John Logie caparison and United States scientist Clarence W. Hansell patented the idea of using hollow glass pipes to transmit television images in the 1920s. However, the tubes patented were real poor quality and experienced signal loss very easily. Bard and Hansell also ran into the same problem Bell did, not having a constant, sharp light source (Hecht, 1999).Solving Bard and Hansells p... ...singly being used in every aspect of communications. When AT&T started using fiber optics in 1979, telephony was revolutionized. Today, the fiber optics industry is growing faster and faster. Over 90 % of long distance ca lls are now transmitted via fiber optics (Concise, 1994). Hopefully, someday there will be no limit to speed in the telecommunications industry because of fiber optics.Works CitedCheo, P. (1990). Fiber Optics and Optoelectronics Second Edition.
