24、rd operate in transverse electromagnetic mode(TEM)and are suitable for use in a wide range of digital and analogue applicationsincluding CATV, radio frequency systems,instrumentation, broadcasting,telecommunications and data network systems. Various constructions and materialsprovide for indoor and

25、outdoor applications, including underground and overheadinstallations, and other environmental protection characteristics.Generally,cables are designed for use in 50 Ohm and 75 Ohm characteristic impedancesystems, although other types (e.g. 93/95 Ohm) are also covered.Coaxial cables defined by this

26、standard maybe incorporated into hybrid cableconstructions with optical fibre or multi-element cable components.All cables covered by this standard may be subjected to voltages greater than 50 V a.c.or 75 V d.c. However,these cables are not intended for direct connection to the mainselectricity supp

27、ly or other low impedance sources.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions fromother publications. These normative references are cited at the appropriate places in thetext and the publications are listed hereafter. For dated references, sub
