Abstract
Optical fiber cable suffers from some fault such as bending, crack and break which deteriorate the performance of the cable. The level of the signals transmitted in the cable attenuated very highly according to the faults. An experimental test has been carried on normal single mode cable. Different types of defects have been created on the same cable such as bending, crack and break. The results of the tests of the faulty and un faulty cables are compared. It is found that the spectral properties of the faulty cable are changed according to the type of the defect. The frequency spectrum of the exited cable has been changed due to the changes of the faults. The type of the fault is detected and identified according to the changes of the natural frequencies of the excited cable. The natural frequency of cable with different crack is evaluated by using experimental work and are compared with the results by using analytical solution and Artificial Neural Network (ANN) data. The results showed that the natural frequency is changed by changing the depth or position of crack, then, the crack position or its size can be determined by evaluating the natural frequency of the cable. The comparisons of the results of both techniques are showed a good agreement. The experimental and ANN data showed a maximum error <1% and the comparison of the experimental with analytical solution is showed an error <11.26%.
