Download file to see previous pages The phenomenon of guiding light through bent glass has been early given by Leonardo DaVinci in one of his notebooks. But, he has not been able to verify this assertion. What is known for certain is that total internal reflection of light in a beam of water, basically guided light, and was given by the physicist John Tyndall in either 1854 or 1870, depending upon which reference you consult. Tyndall showed that light could be bent around a corner while it traveled through a jet of pouring water. Using light for communications came after this. . In 1934 the first patent on guided optical communications over glass was obtained by AT &T. unfortunately, no materials were available at that time to fabricate a glass (or other type of transparent material) fiber optic cable with sufficiently low attenuation to make guided optical communications possible.
Between 1968 and 1970, experts who were working at a number of different academic, industrial and government laboratories dropped the attenuation of glass fiber optic cable from over 1000 dB/km to less than 20 dB/km. Corning patented its fabrication process for the cable. In the late 1980's and 1990's this progress increased with the even lower cost plastic fiber optic cable and Plastic Clad Silica (PCS). In last few years a number of oceanic fiber optic cables have been fabricated. One cable was fabricated in 1990. That was relatively non-controversial. However, as additional cables were introduced, the coastal fishing industry became increasingly concerned about the loss of fishing ground resulting from cable placement, and their liability should they come into contact with a cable. Another cable was fabricated in 1998. To represent their interests a number of coastal fishers formed a committee. After discussion on numerous issues, the fishers and the cable owner reached on a conclusion that has served as the basis for later agreements' between these two groups in Oregon.
Two concentric layers termed the core and the cladding are the basic composition of a fiber optic cable. These layers are shown in the following figure.

Fiber Optic Cable, 3 dimensional view and its basic cross section
Both core and cladding have different refraction indexes with the core having R1 and the cladding R2. Light is piped through the core. In Fiber optic cable an additional coating termed as jacket is also provided around the cladding. Core, cladding and jacket are all shown in the three dimensional view on the left side of above Figure. The jacket is usually made up of one or more layers of polymer. This jacket protects the core and cladding from shocks that might affect their optical or physical properties. It acts like a shock absorber. The jacket also provides protection from abrasions, solvents, Small oil ...Download file to see next pagesRead More

...?Fiber What is the function of fiber in the body? “Dietary fiber from whole grains … helps reduce blood cholesterol levels and may lower risk of heart disease. Fiber-containing foods such as whole grains help provide a feeling of fullness with fewer calories and so help with weight management” (Whole Grains and Fiber, 2010, para. 5). What are some examples of food sources of dietary fiber? Some examples of food sources of dietary fiber are foods made from grain products such as rice, oats, corn or other cereals. Whole-wheat flour, bread, pasta, oatmeal and grit are all grain products and therefore contain...

Optic lenses

...?Optic Lenses The optical lens is a device capable of concentrating (converging) or diverging light. It is formed from a transparent material, most commonly curved (concave or convex) glass. According to the historical facts pertaining to lens gleaned from the Science Fair Project Encyclopedia, the earliest mention of a lens is found in the 424 B.C. play, “Clouds” by Aristophanes, in Ancient Greece which makes a reference to a ‘burning glass’ that is, a convex lens used to produce fire by focusing the sun’s rays. Burning-glasses were known to the Roman Empire (1st Century A.D.) as well. The Roman emperor Nero in the 1st Century A.D. possibly used a lens in the form of a concave-shaped emerald to correct his myopia while watching... the...

Fiber Optic Cables

...Fiber Optic Cables Digital communication in the current modern era has played a significant role in every sector including the social and economical sector. The creation of advanced technologies in terms of communication has considerably augmented the scope for the range of services that are travelled within the computer networks. This is the stage for declaring advantages related to fiber optics, as it is a carrier for providing limitless bandwidth that is not comparable with any other carrier or medium currently existed. Without fiber optics, applications or systems requiring high bandwidth would not be achievable....

Fiber Optic Cable use in the European Market

...Findarticles (2004), Fiber optic cable use reached $24 billion in 2006. Found at: This article emphasizes on the fact that the world is undergoing a sea change in communication infrastructure and Europe is no exception to this truth. In fact, an increased use of optic fiber based communication has been encouraged by the reliance of many sectors of the industry for efficient and proper communication. In order to assess the trends, Electronicast had conducted a research and has come to a conclusion that optical fiber based communication will grow to become a major part of Europe's communication mechanisms. One of the profound reasons for this has been the fact that the rise... in the...

Computer cables

...Unshielded Twisted Pair Network Cable al Affiliation) Some of the environmental conditions that can cause interference toUTP cable include radar signals that disrupt the movement of the cable. External noise or electrical "noise" also interferes with the capacity of a cable to go far (Faber & Rybinski, 2015). Other environmental conditions that disrupt a UTP cable are extreme weather conditions where low temperatures make cables rigid and brittle while high temperatures degrade the material that constructs a cable. The UV radiation in sunlight also causes UTP cable interference. Notably, some of tell-tale...

Fiber optics

... Fiber optics Fiber optics is referred to as the transmission of light through some long rods of fiber which are either glass or plastic. This light travels by internal reflection. The reason is that the medium of the core reflects more than the material surrounding it. As a result, light is continually reflected back into the core as it continues travelling down this fiber. This enables the fiber optic cables to transmit voice, images and even other forms of data in a very high speed that is almost the speed of light. Thus, a fiber optic cable is made up of thin strands of glass or even plastic. Each of the strands is a tenth less as thick as the strand of a human hair and it is capable of carrying approximated ten million calls... . The...
