This specification applies to outdoor drop cables foruse in cabled distribution systemsoperating at temperature between -40 C and +70 C 1) and at frequencies between
25、5 MHz and 3 000 MHz and complying with the requirements of EN 50083. The purpose of this European Standard is to specify the applicable test methods and requirements forthe electrical, mechanical, environmental and fire performance of the cables. 2 Normativereferences The following referenced docume
