Optical cables external covers damage location - art. no. 62770G

The analysis of traditional ways application of measurement on a direct current for search damage location of optical fiber cables of communication has shown the following. Considered ways of measurements are intended for definition of a zone of damages, for the subsequent localization of damage by line-search devices. As consequence, from them is not required high accuracy of estimations. It allows recommending the simplified methods with a margin error up to 10%. Simple bridge and bilateral methods of measurements on a direct current allow receiving estimations with a required error. Approbation of recommended methods has yielded positive results.
