Graded index multimode optical fibre shall be used which meets therequirements of EN 188200 in conjunction with EN 188201 and EN 188202.



EN 187200:2001- 8 -4.2 Attenuation4.2.1 Attenuation coefficientThe typical maximum attenuation coefficient of a single mode optical fibre cable at 1 310 nm is0,45 dB/km and/or at 1 550 nm it is 0,30 dB/km. The typical attenuation coefficient of a category A1a(A1b) multimode optical fibre cable at 850 nm is 2,6 dB/km to 2,9 dB/km (3,0
dB/km to 3,7 dB/km)and/or at 1 300 nm it is 0,7 dB/km to 1,1 dB/km (0,8 dB/km to 1,6 dB/km). Particular values shall beagreed between the purchaser and the manufacturer.The attenuation coefficient shall be measured in accordance with EN 188000, method 301, 302 or 303.4.2.2 Attenuation uniformity4.2.2.1Attenuation discontinuitiesThe local attenuation shall not have point discontinuities in excess of 0,10 dB.The test method best suited to provide the functional requirements is under consideration.4.2.2.2Attenuation linearityThe attenuation linearity measurement is under consideration (may be EN 188000, method 303).4.3 Cut-off wavelength of cabled fibreFor single mode optical fibre cables, the cabled fibre cut-off wavelength λcc shall be less than theoperational wavelength.4.4 Fibre identificationIf the primary coated fibres are coloured for identification, the coloured coating shall be readilyidentifiable throughout the lifetime of the cable and shall be a reasonable match to IEC 60304. Ifrequired, the colouring shall permit sufficient light to be transmitted through the primary coating to allowlocal light injection and detection. Alternatively, the colour may be removable.5 Optical unitsGenerally optical cables comprise several elements or individual constituents, depending on the cabledesign, which take into account the cable application, operating environment and manufacturingprocesses, and the need to protect the fibre during handling and cabling.The material(s) used for a cable element shall be selected to be compatible with the other elements incontact with it. An appropriate compatibility test method shall be defined in the family or detailspecification.Optical elements (cable elements containing optical fibres) and each fibre within a cable element shallbe uniquely identified, for example by colours, by a positional scheme, by markings or as specified inthe detailed specification.Different types of optical elements are described below.



- 9 - EN 187200:20015.1 Slotted coreThe slotted core is either a metallic (for example aluminium alloy) or non-metallic material (for examplepolyethylene or polypropylene) with a defined number of slots, with longitudinal, helical or SZconfiguration along the core. One or more primary coated fibres or optical element is located in eachslot which may be filled with a suitable water blocking compound.If metallic, it must be electrically bonded with the other metallic elements of the cable. If non metallic,the slotted core usually contains a central element which shall be non-metallic. In this case, there shallbe adequate adhesion between the central element and the extruded core in order to obtain the requiredtemperature stability and tensile behaviour for the slotted core element.The profile of the slot shall be uniform and shall ensure the optical and mechanical performancerequired for the optical cable.5.2 Plastic tubeOne or more primary coated fibres are packaged, loosely or not, in a tube construction which may befilled with a suitable water blocking compound. The plastic tube may be reinforced with a compositewall.One aspect of the suitability of the tube shall be determined by an evaluation of its kink resistance inaccordance with EN 187000, method 512, if applicable.5.3 RibbonOptical fibre ribbons are optical fibres assembled in accordance with EN 60794-3, item 5.5.5.4Metallic tube5.4.1Metallic tube on the optical coreA metallic tube (for example aluminium tube) may be applied on the optical core (slotted core, plastictubes).5.4.2Fibres directly located in a metallic tubeOne or more primary coated and coloured fibres are packaged in a metallic hermetically sealed tubewhich may be filled with a suitable compound to avoid water penetration.The surface of the tube should be smooth without any defects.For corrosion protective purposes the metallic tube may be covered by an additional layer which allowselectrical connection.6 Optical fibre cable construction6.1 GeneralThe cable shall be designed and manufactured for a predicted operating lifetime depending on the typeof cable. In this context, the attenuation of the installed cable at the operation wavelength(s) shall notexceed values agreed between the purchaser and the manufacturer. The materials in the cable shallensure that the increase in attenuation shall not exceed the specified value. This specified value mayinclude, for example, the effect of hydrogen.



EN 187200:2001- 10 -There shall be no fibre splice in a delivery length unless otherwise agreed by the purchaser and themanufacturer.It shall be possible to identify each individual fibre throughout the length of the cable.To avoid excess fibre strain induced by the environmental conditions, such as wind or ice loading, thecable construction and particularly the strength members shall be selected to avoid any longitudinalstrain on fibres up to the specified MAT.The optical fibre unit shall house the optical fibres and protect them from damage due to environmental,mechanical forces such as longitudinal compression, crushing, bending, twisting, tensile stress, long andshort term heat effects.The aerial cable types can be divided into the groups :• Optical ground wire or optical phase conductor (OPGW or OPPC),• All dielectric self supporting cable (ADSS),• Optical attached cables (OPAC),• Metallic Aerial Self Supported cables (MASS).These aerial cables have different constructions, environmental and electrical operating conditions forthe use on high voltage lines.6.2 Lay-up of the cable elementsOptical unit elements as described in clause 5 may be laid up as follows:a)single optical unit in the cable centre ;b)a number of homogeneous optical elements using helical or SZ stranding configurations(ribbon elements may be laid up by stacking two or more elements) ;c)a number of hybrid configurations in slotted core such as ribbon or plastic tube .If required, insulated copper conductors in single, pair or quad construction may be laid up with theoptical elements.6.3 Cable core fillingIf specified, the element(s), and in addition the cable core, shall include water blocking compound, orwater swelling element.The bleeding performance of the filling compound from the tube shall comply with EN 187000,method 608.6.4 Strength membersThe kind and materials of strength elements shall fulfil the mechanical and thermal requirements of theoverhead lines. The materials may be metallic or non-metallic.



- 11 - EN 187200:20016.4.1OPGW, OPPC and MASSThe stranded wires used for armouring should be round as per EN 50182 or other cross-sectionalshapes, i.e. trapezoidal, tube, Z-form and can be of the following materials :-aluminium alloyEN 50183-galvanized steelEN 50189-aluminiumEN 60889-aluminium-clad steelEN 61232These specifications give requirements on wire before stranding.After stranding, the wires shall meet the requirements of EN 50182 or requirements shall be mutuallyagreed between the purchaser and the manufacturer.Materials other than those specified can be used if mutually agreed between the purchaser and themanufacturer.In order to reduce the risk of corrosion, it may be necessary for the armouring to be greased. The typeof grease to be applied shall be in accordance with EN 50326.6.4.2ADSS and OPACThe strength member elements may consist of aramid yarns, glass reinforced materials or equivalentdielectric strength members.6.5 Inner sheathA cable inner sheath may be applied by agreement between the purchaser and the manufacturer.6.6 Outer sheathIf the aerial cable has an outer sheath, this shall be made of UV-stabilized weather resistant material inaccordance with clause 22 of IEC 60708-1, unless otherwise agreed between the purchaser and themanufacturer.6.7Sheath markingFor non-metallic aerial cable, the sheath may be marked by a method agreed between the purchaserand the manufacturer.If there is a risk due to the high voltage tracking effects, then sheath marking may be omitted.Metallic aerial cables may also be marked by special agreement between the purchaser and themanufacturer.



EN 187200:2001- 12 -7 Main requirements for installation and operating conditions7.1 GeneralInstallation and operating conditions shall be agreed between the purchaser and the manufacturer.Operating conditions are particularly important for aerial cables. In that respect, the range of conditionscommonly experienced in Europe are given in the relevant Family specification.7.2 Characterization of optical units for splicing purposeIn accordance with EN 187100, sub-clause 7.2, the tests are intended to characterize the different typesof cable elements for splicing purpose.8Design characteristicsTable 1 is a summary of important OCEPL characteristics which may be of relevance to both thepurchaser and the manufacturer.
