| 摘 要： | 提出一种适用于以太网无源光网络的双环冗余结构，为光线路终端、光网络单元及光纤链路提供保护，并给出接口设计、故障容错及恢复机理。与其他保护机制的对比结果表明，该双环冗余结构对于主干光纤故障，恢复时间仅为TU-T结构的45.01%、SRA结构的14.67%。 |
| 关 键 词： | 光纤保护 自愈 环状结构 故障检测 以太网无源光网络 |

| Abstract: | A double-ring optical protection architecture is constructed for Ethernet Passive Optical Networks(EPON) architecture,the Optical Line Terminal(OLT),the Optical Network Unit(ONU) and all fiber links are protected by this architecture,the node-architecture,the fault-tolerant and the restoring mechanism are explained.The compared results show that,when the backbone fiber are failed,the resume time of this architecture is only 45.01 percent of ITU-T and 14.67 percent of SRA. |
| Keywords: | optical fiber protection self-healing ring architecture fault detection Ethernet Passive Optical Network(EPON) |
