Design And Implementation Of Second Class Backbone Transport Network Of SHANDONG CMCC

With the fast development of telecommunications industry and improvement of infrastructure network, it becomes more and more important to construct a high security, flexible, expandable and efficient second class backbone transport network in SHANDONG CMCC. This paper compares several transmission technique from the view of network long term evolution, and proposes the principles of implying IP OVER WDM(Wave Division Multiplexing). Then Dual side-dual node program project is demonstrated. Based on this idea, this paper gives a set of analysis, including network existing condition and circuit demand, delivering solutions for typical problems met in a network plan project of SHANDONG CMCC.
