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

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.

- 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.

- 13 - EN 187200:20019 Optical fibre cable testsThe parameters specified in this standard may be affected by measurement uncertainty arising eitherfrom measurement errors or calibration errors due to the lack of suitable standards. Acceptance criteriashall be interpreted with respect to this consideration. The total uncertainty of measurement for thisstandard shall be less than or equal to 0,05 dB for attenuation.The expression of no change in attenuation means that any change in measurement value, eitherpositive or negative, within the uncertainty of measurement shall be ignored.The number of fibres tested shall be representative of the cable design and shall be agreed between thepurchaser and the manufacturer.The tests applicable for aerial cables are listed below. The minimum acceptance criteria for the differenttypes of cables are given in the relevant family specifications.9.1Classification of tests9.1.1Type testsTests required to be made before supplying a type of cable covered by this standard on a generalcommercial basis in order to demonstrate satisfactory performance characteristics to meet the intendedapplication. These tests are of such a nature that, after they have been made, they need not to berepeated unless significant changes are made in the cable material, design or type of manufacturingprocess which might change the performance characteristics.The tests to be repeated shall be agreed between the purchaser and the manufacturer.9.1.2Sample testsTests made on samples of completed cable, or components taken from a completed cable adequate toverify that the finished product meets the design specifications. Scope and incidence of sample testsshall be agreed between the purchaser and the manufacturer.9.1.3Routine testsTests made on all production cable lengths to demonstrate their integrity.9.2Tensile performanceThe cable shall be tested in accordance with EN 187000, method 501.This test shall be performed to determine the behaviour of the optical unit under tensile load with regardto the following :1.Optical performance (attenuation change)2.Fibre strain3.Strain margin (where applicable)Loading conditions are as per sub-clause 6.3.6.4 of EN 50182 for OPGW, OPPC and MASS. The lengthof the cable test specimen under strain shall be a minimum of 50 m between the mouth of the deadends(other sample lengths may be used if mutually agreed between the purchaser and the manufacturer)and the optical fibre test specimen shall be a minimum of 100 m. The test sample shall be terminatedwith system fittings and in such a manner that prior to strain, no components of the optical unit canmove relative to the cable.
