【Abstract】 The techniques of monitoring optical cables are discussed. An event analysis algorthm based on Gabor transform is given and its performances are analyzed as well. The algorithm theoretically requires a certain SNR value, that is ,r_s,n must be more than 20 dB with the accuracy of judgement greater than 90%, but this range can be reached in real appliction, which means the algorithm is much more applicable.更多还原
