摘要： The present invention relates to an adjustable optical signal delay module, particularly to a module, which adjusts power of an amplified spontaneous emission generated by a semiconductor optical amplifier and reversely feeds the adjusted amplified spontaneous emission back to the semiconductor optical amplifier to vary a group refractive index of the semiconductor optical amplifier and delay the timing of an optical signal, whereby the present invention can replace the pump laser conventionally required by a CPO mechanism. In the present invention, the feedback optical loop comprises a variable optical attenuator, an optical filter, and optical circulators. An user can control the delay timing of optical signals via adjusting optical power in the feedback optical loop. The present invention can decrease the fabrication cost of an optical signal delay module and reduce the volume thereof.

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.
