Collection Of Mstp Based On Sdh Multi-rate Business In Cwdm System Application Research

With the development of the SDH (Synchronous Digital Hierarchy), the largemetro major operation is always made up by large-capability SDH ring networks. TheIP data transport networks is constructed independently. The gathering level of the largemetro networks and the backbone gathering level of the middle range metro networksalways use SDH or MSTP (Multi-Service Transport Platform) ring networks. Asextension of the technique, it is an ideal choice for metro networks joint level usingSDH/MSTP equipments.This article mainly introduces optical communication networks’ development，alloptical network and WDM system, and also discusses the relative technique of theMSTP stress. SDH/WDM/CWDM and the VC of SDH will be presented separately.Then it will expatiate on a suit of system that is constructed at Alcatel OND1692MSEplatform, which also realizes collecting, filing and gathering kinds of differentcommunication operations. The signal passes through CWDM system as a normativeSDH STM-16, and then runs de-operation in the opposite point to realize gathering andtransferring of different velocity operations, which share the bandwidth. The majorwork of this dissertation is analyzing, implementing applications of the SDH VC andLCAS in the system, and debugging the test board.Summarily, the value of this dissertation is that it proposes and designs a newboard frame, while it analyzes and discusses the key points of this frame. This board,which makes use of its highly integration and feasibility, will realizes theimplementation that the traditional optical systems realized by combining varieties ofmodules together. This design makes great progress in optical network’s usability, andis highly valued.
