IEC 61196-6-2:2018

Overview

IEC 61196-6-2:2018 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies detailed requirements for 75-4 type CATV drop cables. These coaxial communication cables are essential components in modern communication networks, particularly for cable television (CATV), surveillance systems, satellite TV reception, and hybrid fibre coax (HFC) architectures. The standard covers cables operating within a frequency range of 5 MHz to 3,000 MHz and provides specifications for cable construction, performance, marking, and testing. It is a critical reference for manufacturers, installers, and system designers seeking high reliability and performance in coaxial cable installations.
