Fiber Optics Wire
665 wordsHistory E-Tek Dynamics was founded in 1983. The company started out as a research and development firm for the Department of Defense and NASA. E-Tek started with only a few typewriters and a few hundred dollars; little did they know that the company was on its way to being one of the leaders in communication. The first task of this new company was to set up high-speed communications cables for NASA. (web) Problem There are many problems that we must overcome. The cables can only be one inch in d...
Limits The Bandwidth Of Multi Mode Fiber
2,293 wordsBoth corporations and individuals today are demanding high bit rates for various applications. Corporations demand this large bit rate for supercomputer interconnection, remote site backup for large computer centers, digital video production and distribution, and many other various tasks. This bit rate demand is seen most prominently in the home users need for large amounts of bandwidth to support the multimedia rich web sites found today on the Internet. These individuals want to be able to poi...
Use For Fiber Optics
361 wordsFiber optics is a kind of optics dealing with the movement of light through fibers or thin rods of glass. If light is put at one end of a fiber, it can move through the fiber with very low loss of intensity, even if the fiber is curved. The simplest use of optical fibers is the moving of light to places hard to reach, for example, inside a dentists drill. Also, bunches of several thousand very thin fibers put together, can be used to view images. Each point of the image made on one side of the b...

1,014 wordsTHE LATEST TRENDS IN TELECOMMUNICATIONS - Week 5 NTC/360 - Network and Telecommunication Concepts May 14, 2005 FIBER OPTICS IN OUR SCHOOLS Fiber optic refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber, about the thickness of a human hair. Fiber optic wire carries much more information than conventional copper wire, and is far less subject to electromagnetic interference. A single glass fiber can carry ...
Future Of Fiber Optics Light
1,154 wordsFiber Optics Fiber Optic Cable Facts'A relatively new technology with vast potential importance, fiber optics is the channeled transmission of light through hair-thin glass fibers. ' [ Less expensive than copper cables [ Raw material is silica sand [ Less expensive to maintain If damaged, restoration time is faster (although more users are affected) [ Backbone to the Information Superhighway Information (data and voice) is transmitted through the fiber digitally by the use of high speed LASERs (...
Advantage Of Fiber Optics
308 wordsThere are many advantages of using fiber over coax systems and free space. One major advantage is eliminating the problem of bandwidth allocation. Frequency assignments are allocated by the FCC for all communication ranges and the FCC will regulate everything from modulation techniques and EMI limits. With fiber optics these problem are eliminated. Another advantage of fiber optics is the high bandwidth available with low attenuation. From the time fiber optic networks were developed, attenuatio...
Fiber Optics Use
1,398 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 that wo...
Long Distance Fiber Optic Communication Systems
928 wordsFiber optics technology is among fastest - growing communications technologies in the world. It is increasingly being used for communications signaling, and electrical control instead of older -technology hardwired system. Fiber optic cable uses light to transmit signals. The core of Fiber optic cable is composed of one or more thin strands of either very pure glass or plastic, millions of which can be bundled together in a sheathing. In 1860, Alexander Graham Bell demonstrated that light reflec...
