Lo, soul! seest thou now not God's goal from the 1st? The earth to be spann'd, hooked up through net-work From Passage to India! Walt Whitman, "Leaves of Grass", 1900. the net is growing to be at a major fee this day. New providers, comparable to telephony and multimedia, are being further to the natural data-delivery framework of the day prior to this. Such excessive calls for on means could lead on to a "bandwidth-crunch" on the center wide-area community leading to degra­ dation of provider caliber. thankfully, technological thoughts have emerged that can offer aid to the end-user to beat the In­ ternet's famous hold up and bandwidth obstacles. on the actual layer, an enormous overhaul of latest networks has been envisaged from digital media (such as twisted-pair and cable) to optical fibers - within the broad sector, within the metropolitan quarter, or even within the neighborhood quarter set­ tings. with the intention to take advantage of the gigantic bandwidth power of the optical fiber, fascinating multiplexing suggestions were built through the years. Wavelength department multiplexing (WDM) is this kind of promising tech­ nique within which a number of channels are operated alongside a unmarried fiber si­ multaneously, each one on a distinct wavelength. those channels should be independently modulated to deal with distinct bit charges and information codecs, if that is so wanted. therefore, WDM carves up the large bandwidth of an optical fiber into channels whose bandwidths (1-10 Gbps) are compati­ ble with top digital processing speed.
