摘要

本文介绍了一种新型光交换器件PSD的硬件结构,该器件可在无源光网络(PON)配电网中对光纤故障进行保护和恢复。开发的PSD原型机在客户端使用,就在光网络单元(onu)之前,以确保在网络发生故障时数据流的连续性和即时修复操作。通过使用光交换机桥接光信号,并在不同路由的工作线和保护线或相邻线上双馈,可以防止光纤/设备故障。当检测到故障时,根据PON故障情况的类型和故障位置,启动保护机制,将光信号方向分流到保护线或相邻线。

Hardware Architecture of Protection Switching Device (PSD)
This paper presents the hardware architecture of a new optical switching device named Protection Switching Device (PSD) for providing protection and restoration against fiber failures/faults in the distribution region of passive optical network (PON). The developed PSD prototypes are employed at the customer end, just before the optical network units (ONUs) to ensure the data flow continuously due to breakdown occur in the network and instantly repair operation. The network is protected from fiber/equipment failures by using optical switches to bridge the optical signals and dual feed them on diversely routed working line and protection line or neighbor line. When the failure is detected, the protection mechanism will be activated and divert the optical signal direction to the protection line or neighbor line according to the types of failure condition and location of failures in PON.
