摘要： Provided are a ranging method and a communication method for an optical network, an Optical Line Terminal (OLT), an Optical Network Unit (ONU), and an optical network system. The OLT sends a broadcast message to the ONU, the broadcast message being used to indicate an uplink bandwidth allocated to the ONU. The OLT opens a quiet window for the ONU in a predetermined region. The OLT receives an uplink signal sent by the ONU at the quiet window.

摘要： The disclosure relates to an OTDR path detection device and method, and the device includes an optical input interface, an optical output interface, a test light transmission unit, an optical assembly, a test light reception unit, a data processing unit, a micro control unit, a power supply unit and a communication interface unit. In the disclosure, a detection light transmission function, a scattered light and reflected light reception function, a detected data processing function and a unit control function are integrated. A fiber optic network to be detected can be detected in real time through fixing the integral optical transmission/reception device in a fiber optic network to be detected, and the normal transmission of serving light is not affected, thus a specialized OTDR meter for fiber optic detection and related testing devices are no longer needed, thereby simplifying steps for optical fiber failure detection and lowering complexity of optical network maintenance and corresponding cost.
摘要翻译：本发明涉及一种OTDR路径检测装置和方法，该装置包括光输入接口，光输出接口，测试光传输单元，光学组件，测试光接收单元，数据处理单元，微控制器单元，电源单元和通信接口单元。在本公开中，集成了检测光透射功能，散射光和反射光接收功能，检测到的数据处理功能和单元控制功能。通过将整体式光发送/接收装置固定在要检测的光纤网络中，可以实时检测待检测的光纤网络，并且不影响服务光的正常传输，因此，专门用于光纤的OTDR仪表检测和相关测试设备不再需要，从而简化了光纤故障检测的步骤，降低了光网络维护的复杂性和相应的成本。
