Fiber Optic Cable Fiber Optics
1,581 wordsFiber optics is a cable that is quickly replacing out-dated copper wires. Fiber optics is based on a concept known as total internal reflection. It can transmit video, sound, or data in either analog or digital form. Compared to copper wires it can transmit thousands of times more data (slide 2). Some of its general uses are telecommunications, computing, and medicine. The very first fiber was made in 1870 by the British physicist John Tyndal. In this experiment that he showed to the Royal Socie...

Fibre Crystal Mid Infrared Lasers
1,998 wordsFibre crystal mid-infrared lasers As we know, a laser is an optical oscillator made out of a gas, liquid or solid with mirrors at both ends (see, e. g. , The Computer Language Company Inc. , 2007 b). To make the laser work, the material is pumped with light or electricity. This pumping has excited the electrons and has caused them to jump to more high orbits. Some electrons do spontaneously drop back to lower energy levels what releases photons (i. e. quantum's of light). The photons do then sti...

Warning Signs Radio Frequency
2,299 wordsBugging (Everybody's Favorite Subject) A Bug is a device which is placed in an area which then intercepts communications and transmits them out of that area to a listening post. There are five categories of Bugs: (Acoustic, Ultrasonic, RF, Optical, and Hybrid). Acoustic is the placing of a water glass, stethoscope, or rubber tube into an area and directly intercepting the communication with the naked ear. Ultrasonic is a technique to convert the sound into an audio signal above the range of huma...

Fiber Optic Cable Fiber Optics
4,355 wordsOur current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copper wire of a century ago to todays fiber optic cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. Todays low-loss glass fiber optic ...

Black And White Electrical Impulses
2,017 wordsOverview Digital cameras capture images electronically and convert them into digital data that can be stored and manipulated by a computer. Like conventional cameras, digital cameras have a lens, aperture, and shutter, but they dont use film. When light passes through the lens it is focused on a photo-sensitive electronic chip called a charged coupling device (CCD). The CCD converts light impulses into electrical impulses (also called analog signal forms). The signals are fed into a microprocess...

Radio Wave Service Providers
1,531 wordsBandwidth is the capacity for carrying digital information. In the past few years, bandwidth has been increasing at roughly twice the rate of computing power. Data traffic has been doubling every 100 days (according to the U. S. Department of Commerce) and it is predicted that that Internet traffic will reach 16 million terabytes by 2003. Fiber is the transport medium of choice. It out performs copper, coaxial cable, and high frequency radio in data-carrying ability. As service needs increase, f...

Fibre Optic Endoscopes Fibre Optic Endoscopy Fiber
4,917 wordsFiber optics produced by special methods from silica glass and quartz which replaced copper wire is very useful in telecommunications, long distance telephone lines and in examining internal parts of the body (endoscopy). Equipment for photography is available with all current fiber-optic endoscopes. Through a process known as total internal reflection, light rays beamed into the fiber can propagate within the core for great distances with remarkably little attenuation or reduction in intensity....

Fiber Optic Cable Fiber Optics
1,613 wordsThe world of fiber optic technology seems to be new. While in actuality it dates back to the 1800 s. It was primitive but it was a form of fiber optic. In this paper I will be telling you what a fiber optic cable is made of, how a fiber optic system works and a history of fiber optics from the 1800 s to today. Lets take a look at the optical fibers, what these fiber do is carry the light which is transmitted to the destination. Now we will look at what a cable is made of. A cable is made up of f...

Fiber Optics Mode Fiber
4,129 wordsSome of Fiber Optics Thesis: Some of the important features of the fiber optics that we are interested are discussed below. Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size. Fiber optics are used mainly to use effectively its high bandwidth. On a single fiber lots of information / data can...

1,254 wordsFire Optics Pag Preface Fibre optics is an emerging form of technology that uses minute fibres of glass or plastic to transmit light. The light source and method of delivery can be modified to transmit computer data, such as images and sound, or simply luminescent light. In recent years, the advancement of fibre optic technology has increased greatly. Many of these advancements, along with an explanation of the technology and societal implications will be discussed within this essay. Introductio...

Speed Of Light Degrees Celsius
1,124 wordsThe Properties of Light Applied to Fibre Optics One of the basic properties of light is that it travels in straight lines and can have it? s direction changed. This is the property which is applied to achieve the purpose of Fibre Optics which is to carry light from one place to another. The way this is done can be explained by the principle of refraction. This is the principle which governs the behaviour of light as it passes from one transparent substance to another. It states; if a ray of ligh...

1,891 wordsMy research paper is about the anatomy of an optical illusion. Optical Illusions are relevant to aviation in that the main guidance system of most aircraft on most flights is the pilots eyes. Everyone, including pilots, is susceptible to an optical illusion. The hazards of optical illusions are many considering that at any time during the flight they can cause a healthy and experienced pilot to become confused, delusional and generally disoriented with obvious possible consequences. This is why ...

Carbon Atom Molecular Formula
2,405 words3. 2 Lots of carbon compounds seem to be isomers. What is an isomer? In organic chemistry, there are many examples of different compounds which have the same molecular formula as each other, but different arrangements of the atoms in their molecules, (different structural formulae). These compounds are said to be isomers of one another. Isomerism also occurs in inorganic chemistry, but it is less common. There are two types of isomerism common in organic chemistry: structural isomerism and stere...

M P H Black Hole
3,742 wordsBlack holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einsteins general theory of relativity, we have to delve into some results of this theory to understand black ...
