【Abstract】 Optical label switching technology is one of realizations of optical packet switching network. In recent years, this technology is getting more concern because it is easy to implement. This paper introduces the principle of optical label switching. In the paper, analysis, comparison and experiment were done among several optical label switching technologies, such as orthogonal optical label, SCM, TDM, OCDM and WDM . We hope this article can provide a theoretical base for realization of the next generation of CATV.更多还原
