Amount Of Light Fiber Optics
1,073 wordsEverything You Ever Wanted to Know About dB But Were Afraid to Ask Telecommunications systems used electrical signals and copper wire to transmit voice messages long before lasers, lightwave's and fiber optic cable. To describe and measure power levels in electrical systems, telecommunication engineers used the standard unit of decibels to express gain or loss and relative power levels. Meanwhile, scientists working with fiber optic signals were using units of milli watts (mW) to determine the a...

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...

An Introduction To Fiber Optics Technology
1,471 wordsThroughout time, speed and efficiency in the telecommunications industry has progressed at a rapid pace due to fiber optic 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 invention was only the beginning of a great addition to telecommunications, one t...

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...

5,102 wordsIs There Any Medical Potential for Marijuana? Marijuana is one of the oldest cultivated plants (Nahas 8). Since it became illegal in 1967, there have been questions of whether or not it is good for purposes, such as medicine, other than being a leisure drug. Debates between pro and con groups for the use of marijuana in the medical profession, have been heated and in recent months, referendums have been pasted in a least three states to make it accessible for medical treatment. Personally, I fee...

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....

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...
