Premium Optical fiber Computer network
waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide. 3. FTTH: Short for fiber-to-the-home‚ the installation of optical fiber from a telephone switch directly into the subscribers home. Fiber optic cable is an alternative to coaxial cable. 4. Simplex: refers to one-way communications where one party is the transmitter and the other is the receiver. An example of simplex communications
Free Light Refraction Snell's law
History Alexander Gurwitsch around 1930 Around 1923 Alexander Gurwitsch discovers an "ultraweak" photon emission from living systems (onions‚ yeast‚...)‚ since he suggested connections between photon emission and cell division rate. He calls this photonemission "mitogenetic radiation". His experiments indicate that the wavelength is in the range around 260 nm (Bibliography under Gurwisch and also Ruth (1977‚ 1979)). Around 1950: Russian scientists rediscover "ultraweak photon emission"

LASER in 1958 and fabrication of low-loss optical fiber in 1970. When we hear of optical communications we all think of optical fibers‚ what I have for u today is AN OPTICAL COMMUNICATION SYSTEM WITHOUT FIBERS or in other words WIRE FREE OPTICS. Free space optics or FSO –Although it only recently and rather suddenly sprang in to public awareness‚ free space optics is not a new idea. It has roots that 90 back over 30 years-to the era before fiber optic cable became the preferred transport medium

along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH: : Fiber reaches the boundary of the living space‚ such as a box on the outside wall of a home. Passive optical networks and point-to-point Ethernet are architectures that deliver triple-play services over FTTH networks directly from an operator’s central office. 4. SIMPLEX: A link that can only carry a signal in one direction. A fiber-optic cable or cord carrying a single fiber. Simplex cordage is mainly

advancement of technology‚ metal/conductive textiles found extensive functional applications. These materials have high electrical conductivity and radar reflecting property‚ yet are lightweight and flexible. Various methods have been developed to coat fibers and textile materials by metals. » sputter coating » coating metal powder with binders » electro less coating » vacuum deposition Many technical applications demand properties which cannot be obtained by simply processing common textile material
