Fiber optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Light forms an electromagnetic carrier wave that is modulated to carry information. Fiber is preferred over electrical wiring when a large bandwidth, long distance or immunity to electromagnetic interference is required. Fiber optic is used by many telecommunications companies to transmit telephone signals, Internet communications and cable television signals. Researchers at Bell Laboratories achieved internet speeds of more than 100 petabytes × kilometers per second using fiber optic communications.
Fiber optic is used by many telecommunications companies to transmit telephone signals Internet communications and cable television signals. Due to much lower attenuation and interference, fiber optic has great advantages over existing copper cable in long distance and high demand applications. However, infrastructure development within cities was relatively difficult and slow, and fiber optic systems were complex and expensive to install and operate. Due to these difficulties, fiber optic communication systems have been installed mainly in long distance applications, where they can be used with all their transmission capacity, which compensates for the increased cost. Since 2000, the prices of fiber optic communications have decreased considerably.
The price for deploying fiber in the home has now become more profitable than deploying a copper-based network. Prices have dropped to $ 850 per subscriber in the US UU And lower in countries such as the Netherlands, where excavation costs are low and housing density is high.
Since 1990 when optical amplification systems were commercialized, the telecommunications industry has established an extensive network of inter-oceanic and transoceanic fiber communication lines. For 2002, an intercontinental network of 250,000 km of submarine communications cable with a capacity of 2.56 Tb / s was completed, and although the specific network capabilities are privileged information, investment reports in telecommunications indicate that the capacity of the network has increased dramatically since 2004.
