摘要
在光网络层面上,利用4个OADM节点互连构成环网的实验条件,在每两个节点间主光通道和保护通道均采用80 km标准G.652光纤连接进行保护倒换实验,从光纤断裂与节点失效两个方面进行实验,光网络层面的50 ms保护倒换是可行的。实验得出的结论对于WDM光网络组网规划有一定的参考意义。
In the light of the network level,the paper presnts to use 4OADM nodes interconnected to form rings experimental conditions.Every pair of two nodes in the main optical channel and every protection channel all adopt 80 kilometres of standard G.652 optical fiber connection and protection switching experiments are made.The fiber fracture and failure of nodes with two aspects are carried out in the experiment,and the optical network level 50ms protection switching is feasible.Conesequently,the WDM optical network planning has certain reference significance.
