The authors of the article examine the problem of electrothermal degradation of fiber optical communication lines arranged on the high-voltage power lines pylons. The possible methods of reduction of high-voltage line electric field influence on fiber optical communication lines were studied. There is also the method of possible calculation and choice of optimal suspension place for fiber optical cable on a high-voltage line pylon. This method can be applied for one of the high-voltage line masses disposition cases.

In this article authors give information about problem of fiber-optical communication lines thermal-electric degradation and its consequences and study main reasons and factors which have an influence upon the degree of thermal-electric degradation. Possible and the most promising research ways are examined in this subject area; they let not only study this subject of fiber-optical communication lines thermal-electric degradation in detail but to solve this problem in whole.
