OTN网络中光交叉设备的选择

Selection of Optical Cross Equipment in OTN Network

随着5G、大数据、云业务的蓬勃发展,Mesh化组网成为趋势,这就要求OTN网络具备更灵活便捷的光交换技术。在OTN网络光层引入ROADM(可重构光分插复用器)、OXC(光交叉连接)等技术实现灵活调度,已成为全光网2.0的重要技术创新,文章以某主流厂家主流光交叉设备的相关参数为例,结合运营商实际运维建设环境,从三个方面进行论述分析,针对不同的网络层级应用场景提出光交叉设备选择的建议。

With the vigorous development of 5G,big data,and cloud services,Mesh networking has become a trend,which requires OTN networks to have more flexible and convenient optical switching technology.The introduction of ROADM (Reconfigurable Optical Add-Drop Multiplexer),OXC (Optical Cross-Connect) and other technologies at the optical layer of the OTN network to achieve flexible scheduling has become an important technological innovation of all-optical network 2.0.This paper takes the relevant parameters of a mainstream manufacturer’s mainstream optical cross equipment as an example,combined with the actual operation and maintenance construction environment of the operator,discusses and analyzes from three aspects,and proposes suggestions for the selection of optical cross equipment aiming at different network-level application scenarios.
