How Fiber Optics Work
Thesis: In a fiber optic tube, the speed of light reflects from the cladding no matter what angle the fiber itself gets bent, even a full circle. Furthermore, because the cladding does not absorb any light from the core, the light waves can travel great distances.3. Where was Fiber Optics discoveredH. Transmitting Light through Fiber Optic CablesOur current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do i
At the receiving end, an optical sensor decodes the light pulses with a complex set of standard codes. The main disadvantages of fiber optics are the cables are expensive to install. The core is the thin glass center of the fiber where the light travels. The optical fiber conducts the light signals over a distance. Fibers are pulled from the blank at a rate of 33 to 66 ft/s (10 to 20 m/s) and the finished product is wound onto the spool. (Freudenri 4) Optical fibers come in two different types. Total internal reflection as light passes from a more optically dense medium to a less optically dense medium at an angle so great there is no refracted ray (Neff and Zitzewitz 356). The transmitter receives and direct the light signals, by turning them on or off in a sequence. The optical receiver takes the incoming light signals then sends the signal to the user. If the beam through m1 is greater than the critical angle, then the refracted beam will be reflected entirely back into m1 (total internal reflection), even though m2 may be transparent (Freudenri 6) !In fiber optics, the critical angle is described with respect to the parallel axis running down the middle of the fiber. Services will include television, data retrieval, video word processing, electronic mail, banking, and shopping. The silicon and germanium react with oxygen, forming silicon dioxide (SiO2) and germanium dioxide (GeO2). Once the fibers have passed the quality control, they are sold to telephone companies, cable companies and network providers.
