Abstract

The longitudinal lightning surge appearing on the telecom cable between the pair of conductors and ground is changed into the transverse lightning surge between the conductors due to conversion characteristics of the system. the transverse lightning surge overlaps the signal voltage and causes bit errors. In this paper, the longitudinal and transverse lightning surges are deter mined. Using these lightning surges, a new method of estimating bit‐error rate oy simulation (numerical calculation) is proposed. Time domain and frequency domain parameters obtained by actual measurement of lightning surge are used in the simulation. Using this method, bit‐ error rate due to lightning surge can be evaluated easily. Moreover, it can cope with the changes in the telecom system and is superior to the conventional method of evaluating the bit‐error rate using actual lightning surges.
