34、 2015 4 General requirements 4.1 Optical fibres The optical fibre shall conform to the requirements of IEC 60793-2. The fibre type shall be agreed between the customer and supplier. The cabled fibre shall conform to IEC 60794-3. 4.2 Cable element The cable elements shall conform to IEC 60794-3. 4.3
35、Optical fibre cable construction The cable construction shall conform to IEC 60794-3. 5 Details of family requirements and test conditions for optical fibre cable tests 5.1 General Tests on single-mode fibre cables are typically carried out at 1 550 nm. Multimode fibre cables are typically tested at
36、 1 300 nm. Measurement at other wavelengths or range of wavelengths may be agreed upon between the customer and supplier. 5.2 Tensile performance Family requirements 5.2.1For 1 % proof-tested fibres, the fibre strain under long-term tensile load (TL) shall not exceed 20 % of this fibre proof strain
37、(equal to absolute 0,2 % strain) and there shall be no change in attenuation during the test. Under short-term tensile load (TM) the fibre strain shall not exceed 60 % of the fibre proof strain and the attenuation change during test shall be measured and recorded. Other criteria may be agreed betwee
38、n the customer and the supplier. For fibres proof tested at higher levels the safe long-term load will not scale linearly with proof strain, so a lower percentage of the proof strain is applicable. For greater than 1 % up to 2 % proof-tested fibres, TLshall be limited to 17 % of the proof-test strai
39、n (equal to absolute 0,34 % strain for 2 % proof tested fibres).Under visual examination without magnification, there shall be no damage to the sheath or to the cable elements. Test conditions 5.2.2Method: IEC 60794-1-21, Method E1 Fibre length: Finished cable length Tensile load on cable: Long-term
40、 tensile load (TL) and short-term tensile load (TM), where: TM1 W (direct burial or blowing in duct); TM1,5 W (pulling in duct); Other loads may be applied in accordance with particular user conditions, e.g. 2 700 N TL= 0,3 TMFor aerial cables, the long-term tensile load may be greater than or equal
41、 to the short-term tensile load. Diameter of test pulleys: Typically 1 m but not less than the minimum loaded bending diameter specified for the cable.

42、at 1 550 nm during the test and under short-term load there shall be no change in attenuation at 1 550 nm after the test. The installation load shall not be less than the long-term load. Under visual examination there shall be no damage to the sheath or to the cable elements. The imprint of the plat
43、e or mandrel on the sheath is not considered mechanical damage. Test conditions 5.3.2Method: IEC 60794-1-21, Method E3A The default method is the plate/plate test, Method E3A. Optionally, the mandrel/plate test, Method E3B, may be conducted if requested by the detail specification. Short- and long-t
44、erm tests may be conducted separately. Load (short term): 1,5 kN (un-armoured); 2,2 kN (armoured) Load (long term): 0,75 kN (un-armoured); 1,1 kN (armoured) 5.4 Impact Family requirements 5.4.1Under visual examination without magnification there shall be no damage to the sheath or to the cable eleme
45、nts. The imprint of the striking surface on the sheath is not considered mechanical damage. There shall be no permanent change in attenuation after the test. Test conditions 5.4.2Method: IEC 60794-1-21, Method E4 Number of impacts: One in 3 different places spaced not less than 500 mm apart Impact e

49、the test. Test conditions 5.7.2Method: IEC 60794-1-21, Method E11 The default method is Method E11A. For large and/or stiff cables (e.g. where the mandrel diameter required is 20 d, IEC 60794-1-21, Method E11B may be used. Diameter of mandrel: 20 d For cable incorporating a non-metallic rod and/or metallic armouring, bending shall be limited to a value from 20 d to 80 d. Number of cycles: 3 Number of turns/helix: 4 Te
