WDM-the most needed Technology to Overcome Future Bandwidth Crisis in Data Communication

Abstract

This Paper discusses problems of bandwidth crisis for computer data communication as amount of flow of data in backbone network is increasing exponentially because of increasing use of text, audio, still and motion video data over long distance. The paper discusses about upcoming technique for economic solution to this problem to be adopted. Wavelength Division Multiplexing techniques is one of the economic solution to such bandwidth crisis problem. The paper also discusses about the problem of efficient implementation of such a technique. The problem is known as routing and wavelength assignment problem.
