41、eral application Section Four: Tests at low temperatures. 3 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
42、15 years. In this context, the attenuation of the installed 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
43、length unless otherwise agreed by the customer and the supplier. 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
44、 None. 3.4 Ruggedized fibre None. 3.5 Slotted core None. 3.6 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 withi
45、n the units shall remain parallel and not cross over. An example 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
46、 helically applied, and/or may be embedded in the overall sheath. BS EN 60794-2-30:2008 8 60794-2-30 IEC:2008(E) 3.10 Ripcord None. 3.11 Sheath The optical fibre ribbon shall be uniformly covered with a protective sheath generally as shown in Figure A.1. 3.12 Sheath marking If required, the cable sh
47、all be marked as agreed between the customer and the supplier. 3.13 Identification The coated fibre shall be distinguishable by means of colour coding and positioning. For example (see Figure 1): a) a fibre ribbon has an identification coloured fibre on one side and a sub-identification coloured one
48、 on the other side; b) the identification and the sub-identification coloured fibres are the first and the last in the fibre ribbon, respectively; c) any colour of the identification colours group is different from that of the sub-identification colours group; d) the colour types and the order used
49、for identification and sub-identification should be agreed between the customer and the supplier. The colours of the other fibres shall be agreed by the customer and/or the supplier; e) the colour range used is similar to the first 12 colours described in Table 1 of IEC 60794-2, i.e. blue, yellow, red, white, green, violet, orange, grey, turquoise, black, brown and pink. 2 3 n-1.n1 Optical fibre Identific
