CABLES AND WIRES - Novkabel

TO SM 19 nxIIx0,4x3,5xCMAOptical cable with metal elementsStandard: ZJPTTCONSTRUCTIONCable core:Optical fibre with primary protection.Secondary fibre protection tubes.Tubes and cable core space filling compound.Central messenger, with or without PE layer.Layer insulation from bubbling dust tape.Peripheral messenger: aramid fibre layer over the core.Inner sheath: PE.Armour: galvanized steel tapes.Sheath: PE.APPLICATIONTECHNICAL DATAOptical cables can be used in local telephone network as joit cables, in interlocal telephone networks as inter local cables and for operation of incomingline transmission systems. The installation can be done directly into theground or by inserting into the telephone tubes.Optical characteristics:Mode area diameter/coating diameter/primary protection (μm) 9,2/125/250Attenuation:at 1300 nm (dB/km) 0,40at 1550 nm (dB/km) 0,25Dispersion:at 1300 nm (ps/(nmxkm)) 3,50at 1550 nm (ps/(nmxkm)) 18,00Tensile strength, max (N) 1500120ConstructionDiameterMass[mm][kg/km]TO SM 19 1x6xIIx0,4x3,5xCMAN 18,3 380,0TO SM 19 2x6xIIx0,4x3,5xCMAN 18,3 380,0TO SM 19 3x6xIIx0,4x3,5xCMAN 18,3 380,0TO SM 19 4x6xIIx0,4x3,5xCMAN 18,3 380,0TO SM 19 6x6xIIx0,4x3,5xCMAN 18,3 380,0TO SM 19 8x6xIIx0,4x3,5xCMAN 19,4 440,0TO SM 19 10x6xIIx0,4x3,5xCMAN 19,4 440,0TO SM 19 12x6xIIx0,4x3,5xCMAN 21,9 532,0Permissible temperatures:- before and after installation from -20 0 C to +50 0 C- at laying from 0 0 C to +40 0 CMarking the cable TO SM ab n x T x A x B x STO – basic label for telecommunication cable with optical fibresSM – additional label for cable with monomode fibresab – armour and insulation label (03 – PE sheath; 04 – PVC sheath)n – number of fibres in the cableT – specified optical window (I – 850 nm; II – 1300 nm; III – 1550 nm)A – cable attenuation in dB/kmB – coefficient dispersion in ps/(nmxkm)S – additional label of one of more lettersC – tube secondary protection; M – filled cable; A – aramid fibre cable; N – non metal cable
