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
They will have full control of their programming both in the times they choose to watch it and in how much they watch at a time or how many segments they choose to view more than once or to skip over utilizing fast forward, rewind and pause controls which serve the same functions as VCRs. Previously limited to sound only, telephones can now be linked with live video images of each speaker. Each fiber is composed of two parts, the core and the cladding. The cladding around each fiber serves to reflect the light traveling through the fiber back inward into the core of the fiber and to prevent the escape of the light out the walls of the fiber. Movies can be "piped" into our homes at will at any specific time the customer desires. Because they are not subject to electrical interference and have the capability of transmitting huge amounts of data, fiber optic technology is far superior to traditional systems of information transfer using copper cables. With new advances in technology even the remaining copper wire systems can be used to receive large amounts of information over short distances while simultaneously allowing, for example, traditional voice transmissions. The core is composed of the glass or plastic and does the actual transmission of data. The union of the two technologies would expedite fiber optic connection and capability substantially. Fiber optics is not only the wave of the future, it is now. 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. When several single mode fibers are connected each connection must also be very precise and exact. The core is typically covered in a sheath referred to as cladding.
