36、or ribbon cables 1 Scope This part of IEC 60794 is a family specification which covers optical fibre ribbon cables for indoor use. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this standard. Clause B.2 contains requirements that supersede the normal

37、 requirements in case the cables are intended to be used in installations governed by the MICE table of ISO/IEC 24702. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated r

38、eferences, the latest edition of the referenced document (including any amendments) applies. These documents complete the normative references already listed in the generic specification (IEC 60794-1-1, Clause 2, and IEC 60794-1-2, Clause 2) or in the sectional specification (IEC 60794-2, Clause 2).

44、Construction 3.1 General In addition to the constructional requirements in IEC 60794-2, the following considerations apply to indoor ribbon cables. The cable shall be designed and manufactured for a predicted operating lifetime of at least 15 years. In this context, the attenuation of the installed

45、cable at the operational wavelength(s) shall not exceed values agreed between the customer and the supplier. The materials in the cable shall not present a health hazard within its intended use. There shall be no fibre splice in a delivery length unless otherwise agreed by the customer and the suppl

46、ier. It shall be possible to identify each individual fibre throughout the length of the cable. 3.2 Optical fibres and primary coating Multimode or single-mode optical fibres meeting the requirements of IEC 60793-2 shall be used. 3.3 Buffer None. 3.4 Ruggedized fibre None. 3.5 Slotted core None. 3.6

47、 Tube None. 3.7 Stranded loose tube None. 3.8 Ribbon structure The ribbon structure shall conform to 6.5 and 8.2.3 of IEC 60794-3. Fibres shall be formed into units of typically two, four, six, eight, or twelve fibres each. The fibres within the units shall remain parallel and not cross over. An exa

48、mple of a ribbon construction is shown in Figure A.1 3.9 Strength and anti-buckling members The optical fibre ribbon cable may incorporate a tensile strength member. The strength member can be a layer of suitable material, longitudinally or helically applied, and/or may be embedded in the overall sh
