Wavelength Division Multiplexing (WDM)

Introduction
In a WDM system, each of the wavelengths is launched into the fiber, and the signals are demultiplexed at the receiving end. Like TDM, the resulting capacity is an aggregate of the input signals, but WDM carries each input signal independently of the others. This means that each channel has its own dedicated bandwidth; all signals arrive at the same time, rather than being broken up and carried in time slots. The difference between WDM and dense wavelength division multiplexing (DWDM) is f ....etc

This paper deals with the twin concepts of optical networking and dense wavelength division multiplexing. The paper talks about the various optical network architectures and the various components of an all-optical network like Optical Amplifiers, Optical Add/Drop Multiplexors, Optical Splitters etc. Important optical networking concepts like wavelength routing and wavelength conversion are explained in detail. Finally this paper deals with industry related issues like the gap between research and the industry, current and projected market for ....etc

An optical network consists of wavelength routers and end nodes that are connected by links in pairs. The wavelength-routing switches or routing nodes are interconnected by optical fibers. Although each page link can support many signals, it is required that the signals be of distinct wavelengths. Routers transmit signals on the same wavelength on which they are received. An All-Optical wavelength routed network is that wavelength-routed network that carries data across from one access station to another without any O/E (Optical/Electronic) co ....etc

The technology of combining a number of optical wavelengths and then transmitting the same through a single fibre is called wavelength division multiplexing (WDM). Conceptually, the technology is similar to that of frequency division multiplexing (FDM) used in analogue transmission. Dense wavelength division multiplexing (DWDM) is anew born multiplexing technology in the fibre optic transmission, bringing about a revolution in the bit rate carrying capacity over a single fibre. The emergent of DWDM system is one of the important phenomena in de ....etc

Aim:
To provide easily accessible and appropriately structured information about: pioneering European ATM networking platforms (also called testbeds); important research and development activities closely related to these platforms; and significant trial results, being the outcome of such research activities.
To provide a facility for on-line remote monitoring and, to a more limited extent, control of the said ATM networking platforms.
To use the monitoring facility, so as to allow to an enlarged audience to witness selected importan ....etc
