OTN(光传送网)作为一种新型组网技术已成为国内外运营商和行业系统新建和改造大容量宽带波分传输系统的主流技术,并将在专网的波分局干网和局内骨干网绽放出更强的生命力。通过对专网波分系统改造工程实践,从现状和需求分析、技术比选、组网方案、保护技术、设备选型、设备配置关键要素与SDH系统的联合组网思路等方面做了关于OTN技术在专网运用的方式探讨。
As a new type of networking technology, OTN (Optical Transport Network) has become the mainstream technology for newly established and renovated large-capacity broadband WDM systems at home and abroad by operators and industry systems. OTN (Optical Transport Network) Blooming a stronger vitality. Through the engineering practice of WDM system renovation project, this paper makes a detailed analysis on the OTN (Wireless Local Area Network) from aspects such as the status quo and requirements analysis, technology comparison and selection, networking scheme, protection technology, equipment selection, key elements of equipment configuration and SDH system networking, Discussion on the Way of Using Technology in Private Network.
