<p>A method for identifying and positioning the origin of at least one fault in a meshed optical network (1) comprising nodes(2-9), connected to each other through optical line sections (13), a channel being created along an optical path (10) comprising the following successive steps:
- determine the state of maintenance or extinction of said channel at at least one measurement point, by measuring the optical power of said channel at said measurement point (21,31,34-36) of nodes (2-9) on said optical path (10)
- determine at least one defective node or component by comparison of said states, with a predetermined state. A state change between two measurement points (21,31,34-36) not corresponding to a predicted state change is indicative of a defective node or component between these two measurement points. A method for identifying and positioning the origin of at least one fault actively uses a controlled extinction of a defective optical channel.</p> |
