通过宽带IP城域网两种不同技术方案的比较分析,IP over fiber技术由于省去了中间层,可以与以太网接入网实现无缝连接,而且通过CWDM和万兆以太网进行带宽扩展,成本较低。在专线业务(尤其是透明以太网传输)、TDM业务需求高,市场容量大的城市,IP over MSPP则是一种快速产生收入的宽带IP城域网解决方案。此外,在传统电信网的升级中,MSPP也是一种较理想的过渡方案。
Through the comparative analysis of two different technical solutions of broadband IP MAN, IP over fiber technology can realize seamless connection with Ethernet access network by eliminating the middle layer, and bandwidth expansion through CWDM and 10 Gigabit Ethernet. Lower cost. In the private line business (especially transparent Ethernet transmission), TDM business needs high market capacity of large cities, IP over MSPP is a fast revenue-generating broadband IP MAN solution. In addition, MSPP is also an ideal transitional solution in the upgrade of traditional telecom networks.
