The Use of Fiber Optics in Communications The field of communications is one in which the technologies are changing on an almost daily basis. Numerous different technologies have been pursued over the past few years; each designed to essentially accomplish several basic purposes in terms of community service. Three of the most actively pursued application include interactive distance learning, video conferencing, and entertainment. While it is the first two, video conferencing and interactive distance learning, which would serve to the best advantage in terms of education and business; it is the last, entertainment which has the most appeal to the largest number of people. The application of various communications applications in…show more content…
Light enters one end of the fiber from a light bulb, laser, or some other source, and travels essentially unimpeded all the way to the length of the fiber where it is intercepted by a photosensitive detector such as an electronic device or even the human eye. The distance of travel varies according to the use to anywhere from just a few inches to over one-hundred and fifty miles. Fiber optic cable can transmit large amounts of information over one-hundred and fifty miles almost instantaneously. “While it takes five hours to transmit the contents of an encyclopedia over copper wires, the entire work can be transmitted in less than a minute over fiber optics” (Yawn PG). Single Mode/Multi-Mode Fibers referred to as single mode are most often used for the longer distance transmissions. Multi mode fibers are used in applications requiring less distance. They are less expensive than single-mode fibers and accept light from a larger variety of sources and from different angles. Single-mode fibers are smaller in diameter than are multi-mode and are particular both about the type of light they will accept and the angle at which it can be introduced. They typically accept light only when it is directly input to the axis of the fiber. This ability requires special light sources such as lasers and
