池化OTN技术在县乡层面的应用探究OA

The rapid development of various emerging services in recent years has imposed new requirements on optical transport network(OTN)architectures.Focusing on the challenges encountered by operators in the construction of county and township wavelength division multiplexing(WDM)networks,this study explores the application of advanced WDM technologies at the county and township lev-els,using the deployment of pooled OTN in Sichuan Province as a case study.The paper introduces pooled OTN technology and conducts a comparative analysis with traditional WDM in terms of advantages,disadvantages,and applicable scenarios.Based on an examination of the current challenges and demands in county and township application scenarios,the deployment scheme and testing process of the pooled OTN system are comprehensively described.Finally,the practical value and economic benefits of the technology are objectively evaluated.
