Improving Fibre Optics Transmission with Wave Length Division Multiplex through Routed-Switching Network

Abstract

The Optics Fiber link is implemented to satisfy various types of networks, with a wide range of transmission capabilities and improved speed in signal delivery. The link carries multiple signals and for adequate transmission, multiplexing of signals, each signal component, is aggregated and transmitted over a common link which is regarded as multiplexing. The wavelength-routed network bridges the gap of the timeshare, which has retardation on speed and efficiency. The wavelength division multiplex (WDM) is a multiplexing technique designed to suit fiber optics and achieves speed demands, as against time-division multiplexing(TDM) for analog continuous signals (CT) and frequency division multiplexing(FDM) for discrete-time signals(DT). The synchronous optical network (SONNET) and synchronous digital hierarchy (SDH) and the Asynchronous transfer mode (ATM) create an inter-switching system using various matrix dimensions, of 2 X 2, 8 X 8 and other multiples to achieve a versatile routing switching technique. Wavelength division Multiplex and it’s a dense modification (DWDM); have greatly improved the quality and speed of signal transmission over all other techniques.
