Optical fibre cables - Indoor cables. Detail specification for simplex and duplex cables for use in cords for controlled environment Ingestion-build-47553 BS ISO/IEC 18028-3:2005 provides an1 Scope This part of IEC 60794 is a detail specification. It gives detailed requirements for cables to be used in cords which are intended for use in a category C environment, according to IEC 617531. They are characterized with temperature range between 10 C and +60 C. The fibre requirements for this specification are defined in IEC 60793210 for multimode fibres and IEC 60793250 for single mode fibres. Some deviation to family specification IEC
