  • Use Carbon Fibers
    1,452 words
    Carbon fiber Carbon fibers are produced by using heat to chemically change rayon or acrylic fibers. Carbonization occurs at temperatures of 1000^0 C to 2500^0 C in an inert atmosphere. Carbon fibers are converted to graphite at temperatures above 2500^0 C. Carbon and graphite fibers can also be made from pitch, a residual petroleum product. Products that use carbon fibers include heat-shielding materials, aircraft fuselages and wings, spacecraft structures, and sports equipment. You can golf, ri...
  • Limits The Bandwidth Of Multi Mode Fiber
    2,293 words
    Both 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...
  • Damp Heat Test For Couplers With Epoxy
    2,157 words
    Everything 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, light waves 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 milliwatts (mW) to determine the am...
  • Use For Fiber Optics
    361 words
    Fiber 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...
  • Future Of Fiber Optics Light
    1,154 words
    Fiber 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 (...
  • Asbestos Materials In Schools
    1,411 words
    What is asbestos you ask? Well asbestos is the name for a group of naturally occurring silicate minerals that can be separated into fibers. The fibers are strong, durable, and resistant to heat and fire. They are also long, thin, and flexible, so that they can even be woven into cloth. Because of these qualities, asbestos has been used in thousands if consumer, industrial, maritime, automotive, scientific and building products. During the twentieth century, some 30 million tons of asbestos were ...
  • Spinal Nerve Fiber Regeneration
    2,272 words
    Topic: New ways to aid in nerve regeneration. General Purpose: To inform Specific Purpose: To inform the audience about news techniques and mechanisms that aid in nerve regeneration. Central Idea Statement: The new techniques for nerve regeneration involving magnetic, electrical, and chemical mechanisms look very promising. INTRODUCTION I. The site is rather common: someone in a wheel chair unable to use their lower body, or worse, unable to function from their neck down because of an accident. ...
  • Use Of Manufactured Fibers
    1,879 words
    Today they " re many thousand different materials. Most of them are different types of clothing, or cloth. Good portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities, since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repea...
  • Fiber Optics Use
    1,398 words
    Throughout 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 words
    Fiber 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...
