Fiber+Optics+~+Breezy

Fiber optics is guiding light along the length of a plastic or glass tube. Light is kept in the core of the tube by total internal refraction. The light then shines out at the end of the tube. While these cords are used frequently in today's world, they have actually been around since the early 1840's, but practical application didn't come around until the early 1990's. Then they used this system of lighting for dentistry work. Then in the 1920's it was used in television and radio. In the 30's it was used in internal examinations of patients. In 1952, a physicist invented optic fiber. In the 19th and 20th century they used fiber optics for communications, but they became wildly popular in the 21st century as the demand for television went on the rise. In 1965, fiber optics were finally ready to be used for communication. When NASA went to the moon, they used fiber optics to video everything. Fiber optics are outstanding with long distance communication. Fiber optics can also have many different channels, because they can harbor different wavelengths. This is especially good for communication. Other uses of Fiber Optics include light guides, imaging tools, as lasers for surgery, used with SONAR, wiring aircraft, submarines, and other military vehicles, data storage, to connect servers in a network, HDTV, internet, DVR/TIVO, and in sensory devices that measure pressure, temperature, and many other measurements.
