摘要： The present invention discloses a fiber sensing system with self-detection mechanism which utilizes a central office to control secondary ring architecture formed by fiber sensor, remote node and optical coupler primarily. The secondary ring architecture is connected serially to form a primary ring architecture. The central office has a tunable laser light source that can deliver the light source to the fiber sensor. Since the fiber sensor has reflective ability, all light source signal sent by the tunable laser light source will be detected and measured by the fiber sensor. Thus central office can detect all signals reflected by the fiber sensor and produce a spectrum for analyzing fault point locations. The present invention can greatly enhance survivability and sensing capacity of all fiber sensors, so that when a fault point caused by environmental change within the fiber, it will not effect the overall operation of the sensing mechanism. The application of fiber sensor can also reduce cost and complexity of the overall fiber network topology.

摘要： A circuit for switching a signal path includes a path selection element, a detector, a switch, and a control circuit. A first end and a third end of the path selection element are coupled to the detector and the switch, respectively. The switch is normally in a conductive status for outputting an upload signal through the path selection element and the switch when the upload signal is input from a second end of the path selection element. When a download signal is transmitted to the detector, the detector transmits the download signal to the path selection element and enables a detection signal. The control circuit switches the switch status to an open-circuit status for outputting the download signal isolated by the switch from the second end of the path selection element. Until the download signal is transmitted completely, the control circuit switches the switch status to the conductive status.
