Home / DC Resistance Standard for Composite Optical Cables
DC resistance, per conductor, measured in accordance with ASTM d 4566 (ref B1. IEC 60794-1-1:2023 applies to optical fibre cables for use with communication equipment and devices employing similar techniques. Electrical properties are specified for optical ground wire (OPGW) and optical phase conductor (OPPC) cables. The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes International Standards for all electrical, electronic and related technologies. The technical content of IEC publications is kept under constant review by the IEC. Prysmian has a built-in multi-step quality assurance programme, which covers the entire production process from cable design and raw materials purchasing, to final inspecti tion for any single project.
