摘要
PTN与OTN网络在城域内单独发展的模式,已无法满足LTE、2/3G业务、家集客等各类业务接入产生的"大连接"需求。融合PTN和OTN的POTN部署顺应了多业务发展的趋势,能够解决现有承载网络面临的问题。分别研究技术方案对网络现状的演进和构建大城域光网络带来的性能、效益分析,认为POTN的搭建可显著降低CAPEX和OPEX,简化网络架构,提前布局5G时代的传输承载网。
In the metropolitan networks, the development style of PTN and OTN networks can not meet the requirment of large connections, generated by the traffic flows of LTE, 2/3G,home broadband and other services. POTN, combined with PTN and OTN is proposed and deployed with the development of multi-service, and can solve the problems of bearer network.The technical scheme on the evolution and construction of large optical metropolitan networks is discussed, and the performance and benefit brought by the technical scheme analyzed. Experiment indicates that the construction of PTON could remarkably reduce CAPX and OPEX, simplify the network architecture, and make an in-advance deployment of 5G transmission bearer network.
