Summary:Aspects of the present disclosure aim at configuring an optical time domain reflectometry (OTDR) in a central office such that the OTDR is configured to be operatively coupled with and also configured to periodically poll each fiber at defined intervals and compute/store a reflection signature that can be used to compare with future signatures received from subsequent polls of the fiber to determine a fault (e.g., a fiber cut or breakage) between the central office (CO) and one or more optical network unit (ONU) over GIS. 本公开的方面旨在中心局中配置光时域反射计(OTDR)，使得OTDR被配置为与每根光纤可操作地联接并且也被配置为以限定的间隔周期性地轮询每根光纤，并且计算/存储可用于与从光纤的后续轮询接收的未来特征进行比较的反射特征，以通过GIS确定中心局(CO)与个或更多个光网络单元(ONU)之间的故障(例如，光纤切断或破损)。
