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. |
