Abstract(in English) | A sensing system as a way to gather information in real time from wide areas by reflective fiber-optic sensors and OTDR (Optical Time Domain Reflectometer) is paid great attention, because the system is simple and available at a low cost. Over the long distance, sensors are connected via optical couplers at multi-points, so that calculating the height of reflected light beforehand is important in each connecting point. However, as the reflected light height from sensors is restricted by the dynamic range which is influenced according to the conditions of setting sensors and OTDR, the relationship between the reflected light height from sensors and optical coupler ratio is not necessarily clear. In this paper, the author describes important information of the sensing system design that makes clear the relationship between reflected light height from sensors and optical coupler ratio. |
