Fiber optics
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 applications include interactive distant 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 application in terms of education and business is currently being utilized in remote learning programs and company training programs around the nation. One technology has maintained a position close to the lead in terms of staying in the running to win the coveted spot of the world's most progressive and sought after communications application. This application is that of fiber optics. To understand fiber optics in its application to communications, one must first have an understanding of the technology itself. The transmission of light through thin f
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 special and precise connections both at the light source and to the detector. When several single mode fibers are connected each connection must also be very precise and exact. All of these requirements of course result in greater costs associated with the use of single mode fibers than would be incurred with the use of multi mode fibers but that cost is a necessity of long distance transmission. As businesses move from "Main Street" to a global presence, they experience more and more needs in terms of technology. Often times the various fractions of a business are spread across wide geographic areas and coordination between the various offices is easily disjointed. Technological advancements such as the telephone, e-mail, fax, and videoconferencing become the lifelines which connect one unit with the others. These same technological advances come to the rescue of schools and other organizations which could benefit from a networked approach to their activities. Videoconferencing is particularly useful in that it allows the transmission of visual clues which replicate those of traditional "face-to-face" interactions (Lantz). Videoconferencing is an asset to communication and provides a service that no other technology can currently match in terms of the clear transmission of information. This includes both visual images of others in the conference and of data such as charts and spreadsheets which are being presented. Home entertainment and communication is another area being heavily impacted by fiber optics. Movies can be "piped" into our homes at will at
