spreading of a light pulse as it travels down a fiber when light pulses launched close together(high data rates) spread too much and result in errors and a loss of information. The spectral width determines the number of different wavelengths that are emitted from LED or laser. One way to reduce chromatic dispersion is to narrow the spectral width of the transmitter. Chromatic dispersion can be compensated for with the use of dispersion-shifted fiber (DSF). Laser has a more narrow spectral width

The carbon cycle is the exchange of carbon among three reservoirs or storage places: the land‚ the oceans‚ and the atmosphere The atmosphere has the least amount of carbon‚ followed by the land with it plants and animals‚ also

Chemistry Pg. 1 Carbon Dating Carbon dating is the most reliable‚ commonly used‚ and useful dating method‚ for what it can date. It is used to date late Pleistocene and Holocene artifacts and geologic events up to 50‚000 years decayed. Carbon dating has been very beneficial to the scientific world‚ because it is used in so many different fields of science‚ including archaeology‚ geology‚ oceanography‚ hydrology‚ atmospheric science‚ and paleoclimatology. The radiocarbon dating method was developed

Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more popular to the scientists. Initially‚ it was the spectacularly

Fiber Optics is the Future Tech Talk Advisory: I saw this video and it got my inner tech geek all excited. by Rothalack 6 months ago http://www.gameskinny.com/d3nr8/fiber-optics-is-the-future FDDI stands for Fiber Distributed Data Interface. FDDI uses optical fiber to distribute its data. Standard FDDI will run at 100Mb/s. FDDI is not regularly used because of how expensive it is‚ but offers many advantages that might make you think otherwise. The first and I think most important is the

Carbon‚ an element discovered before history itself‚ is one of the most abundant elements in the universe. It can be found in the sun‚ the stars‚ comets‚ and the atmospheres of most planets. There are close to ten million known carbon compounds‚ many thousands of which are vital to the basis of life itself. Carbon occurs in many forms in nature. One of its purest forms is diamond. Diamond is the hardest substance known on earth. Although diamonds found in nature are colorless and

somewhere on time. Car emissions produce three types of carbon - Carbon Monoxide (CO) and Carbon Dioxide (CO2) and hydrocarbon (CH4) - which are traumatizing both our health and the environment. By itself‚ carbon isn’t a harmful element‚ but one of its characteristics is easily pairing up with majority the elements in the periodic table. Its ability to bond is infinite; it can create many different substances without any problems. Carbon Monoxide is a poisonous gas‚ that leads to severe poisonings
