Abstract
A fault diagnosis method applied to an optical tunnel network system (OPTUNS) having multiple optical switches and multiple optical fibers connected to the multiple optical switches is disclosed and includes following steps: detecting whether the multiple tunnels of the OPTUNS include a faulty tunnel, where each tunnel respectively passes through multiple component parts; when the faulty tunnel is detected, querying the multiple component parts that are passed through by the tunnels within a certain range with the faulty tunnel; respectively calculating a faulty count of each component part queried, where the faulty count indicates the quantity that the component parts being passed through by the faulty tunnels; and outputting one or more of the component parts that have the faulty count of non-zero.
