Fiber optic communication ABSTRACT FIBRE-OPTICS COMMUNICATION Most reference materials that discuss the historical perspective mention about Indian smoke signals. None of these primitive systems was secure due to the spreading of the unguided light. Ideally‚ a communication system should be secure and should not require installation of a cumbersome physical media. Fiber optics satisfied these desires‚ and as early as 1958‚ fiber-optic equipment was being focused for use in the factory. The fiber-optic

FIBER TO THE HOME: THE NEW EMPOWERMENT abstract: In order to offer future higher bandwidth applications‚ the choice for a fiber to the home (FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from

important‚ this being carbon. There are many interesting things about carbon including‚ facts about it‚ its history‚ and what it is used for. Carbon is a very important element‚ in fact‚ life could not exist without it. Carbon (C on the periodic table) is a chemical element and is the sixth most abundant element in the world. Carbon is the 6th element on the periodic table in group 14‚ period 6‚ it has six protons‚ six electrons‚ and six neutrons‚ with an atomic mass of 12.01u. Carbon has a boiling point

May 2‚ 2013 Kristin Ellsworth Face the Facts What are bad fats? Bad fats are saturated fat and trans- fat. Saturated fat have chemical makeup in which the carbon atoms are saturated with hydrogen atoms. Saturated fats occur naturally in many foods. The majority come mainly from animal sources‚ including meat and dairy products. Examples are fatty beef‚ lamb‚ pork‚ poultry with skin‚ beef fat (tallow)‚ lard

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

Particularly‚ optical fiber communication plays a vital role in the development of high quality and high-speed telecommunication systems. Today‚ optical fibers are not only used in telecommunication links but also used in the Internet and Local area networks (LAN) to achieve high signaling rates. What is fiber optic communication? Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic

The Carbon Cycle The element Carbon is the principle block for the organic compounds that make up life. This is because the study of the Carbon Cycle draws upon theories from biology‚ chemistry‚ geology and oceanography in order to understand the movement of carbon throughout the atmosphere‚ hydrosphere‚ and geosphere. Carbon is made up of four electrons that are able to form with each other; this causes the many different forms of carbon. The most popular form of carbon is carbon dioxide; this

Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

destructive nature. I will start by describing the carbon cycle and how elements of my lifestyle impact the cycle. Photosynthesis converts the Carbon dioxide gas that exists in the atmosphere and in dissolved water to organic carbon. Organic carbon is brought back into carbon dioxide gas by a process called respiration. There are sources of organic carbon underground in the form of fossil fuels‚ human emissions and volcanic activity brings the stored carbon back into the cycle. As a human being who feed
