OPTICAL SWITCHING

SEMINAR ON OPTICAL SWITCHING :Explosion of a request for information on the Internet world is creating enormous need for capacity expansion in the next generation telecommunications network. It is expected that the data-oriented network traffic is doubling every year. Optical networks have been widely regarded as the ultimate solution for He has a future of telecommunications bandwidth. Optical deployed fiber links between nodes are capable of carrying terabits information, but electronic switching nodes to limit bandwidth of the network. optical switch nodes to win this limitation. With their increased efficiency and reduced costs optical switches provide the key to both manage the new capacity Dense Wavelength Division Multiplexing (DWDM), and links competitive advantage for the supply of bandwidth, services. However, optically connected to the Internet challenge To overcome signal impairments and network-related parameters. Let discusses the current situation, the benefits and challenges and future trends in optical switches.
