摘要
提出了一种EPON网络中共享支路光纤的V型保护结构。在定量分析的基础上,对V型保护结构结构和光纤全保护倒换方式进行生存性比较。通过MATLAB仿真分析证明,V型保护结构具有与光纤全保护倒换方式相同的平均生存性,但支路光纤成本却是后者的1/2。
A novel protection architecture that shares branch fiber is proposed in this paper. Based on the quantitative analysis to V-protection structure, this paper makes comparison between V-protection structure and full duplex system. Trough simulation in MATLAB, it is proved that the survivability of EPON with V-protection structure equals to that of EPON with full duplex system, what＇s more, the branch fiber cost of EPON with V-protection structure is half of EPON with full duplex system＇s.
