Ahmed rated it it was amazing Oct 20, Sunil rated it really liked it Sep 05, Bafud,an English scientist, and C. W- Hansell, a scientist from the United States,were granted patents for scanning and transmitting television images through uncoated fiber cables.
A few years later, a German scientist named H. Lamm successfully transmitted images through a single glass fiber. At that time, most people considered fiber optics more of a toy or a laboratory stunt and, consequently, it was not until the early s that any substantial breakthrough was made in the freld of fiber optics. In , A. Hopkins and N.
Kapany of England experimented with light transmission through bundles of fibers. Their studies led to the development of the flexible fiberscopa which is used extensively in the medical field. It was Kapany who coined the term "fiber optics" in Townes, an American, and Arthur L. Schawlow, a Canadian, wrote a paperdescribinghow it was possibleto use stimulatedemission for amplifying light waves laser as well as microwaves maser.
Two years later, Theodore H. Maiman, a scientist with Hughes Aircraft Company, built the fust optical maser. The laser's relatively high output power, high frequency of operation, and capability of carrying an extremely wide bandwidth signal make it ideally suited for high-capacity communications systems. The invention of the laser greatly acceleratedresearchefforts in fiber-optic communications,although it was not until that K.
Kao and G. Bockham of the StandardTelecommunicationsLaboratory in England proposeda new communications medium using claddedfrber cables. That was the "big" breakthroughneededto permit practical fiber optics communications systems. Since , fiber optics technology has grown exponentially.
Recently,Bell Laboratories successfullytransmitted 1 billion bps through a fiber cable for miles without a regenerator. By the late s,lossesin optical fibers were reducedto as low as0. By the mid- s,optical voice and data networks were commonplace throughout the United Statesand much of the world.
Wider bandwidth and greater information capacity. Optical fibers have greaterinformation capacity than metallic cables becauseof the inherently wider bandwidths available with optical frequencies. Optical fibers are available with bandwidths up to several thousand gigahertz.
