20080291431 | APPARATUS FOR MONITORING OPTICAL OBSTRUCTIONS IN AN OPTICAL SPLIT NETWORK AND METHOD THEREOF - An apparatus and method for monitoring optical fiber obstructions in an optical split network is described. The monitoring apparatus comprises a broadband-monitoring light source module, an optical circulator, an optical spectral analyzer, a high-density multi-wavelength ODTR, a controlling computer, a wavelength division multiplexer, a specific wavelength optical filter, a monitoring-waveband reflector, and an optical channel selector. The monitoring apparatus utilizes the specific wavelength optical filter and the monitoring-waveband reflector to collectively construct an optical split network optical fiber obstruction monitoring apparatus for the passive optical network having multiple split routes by filtering, reflecting, and transmitting coming lights, so as to achieve the purposes of locating the obstructed split routes and obstruction locations at the same time. | 11-27-2008 |

20130170786 | REMOTE WATER SENSING SYSTEM WITH OPTICAL FIBER - A remote water sensing system and method with optical fiber, comprises a water sensor which is an optical element designed in accordance with the principle of optical path return loss and provided with reusable features to measure the state of having water or not. A monitoring equipment is provided which is an Optical Time Domain Reflectometer (OTDR), an Optical Frequency Modulated Continuous Wave (OFMCW), or a light source power meter, and used to emit monitoring light signals and accept optical signals returned from the water sensor. A signal processing control unit analyzes the optical signal returned from the water sensor to determine whether the monitoring position is touching the water or not. The method can be used in other fields, such as optical closure watering monitoring, telecommunications facilities flooding alarm, and monitoring and alarm for a low-lying area or river water level of a bridge. | 07-04-2013 |
