METHOD FOR TRACING THE UNUSUAL SPOT OF OPTICAL CABLE

摘要

PURPOSE: The abnormality point method of measurement of the optical cable. The accuracy of the abnormality point measurement of the optical cable is maximized. The sensing time can be minimized. CONSTITUTION: The abnormality point method of measurement of the optical cable is as follows. The state of the optical cable is measured every time at the sampling measurement. The measured value which measure in the time of peace when for the state of the optical cable, ideal has no is to the standard value.
