New trends in telecommunication

Abstract

This is the new trend of different wires used in telecommunication like fiber optic and copper wire This study includes various parameters for comparison. For fabrication of any telecommunication, every wire play important role. A pair of Fiber can carry over eight thousand simultaneously voice channels. This paper gives us the idea of high immunity to electromagnetic interference for optical fiber and copper wire. According to this we will explain about Optical Fiber, type, features, theory and principles. Different specification and features of optical fiber cables are also studied. Optical Fiber’s linear features are wavelength window, bandwidth, attenuation and dispersion. Non-linear features are fiber manufacturing, geometry etc. Copper cable has different types such as: Coaxial cable and twisted cable.
