MULTITUBE OPTICAL FIBRE CABLES - TKEST TYPE i\i Impact resistant STANDARDS Construction: ADIF 03.366.780.9 -5th Edition. Fibre: ITU-T G652D DESCRIPTION AND APPLICATION "Loose tube" singlemode optical fibre cables from 16 to 128 fibres for installation in tunnels or indoors with double, fire resistant, halogen-free TKEST armoured sheath. Protected against rodents. CONSTRUCTION • Central reinforcing element: Dielectric fibreglass (FRP). • Loose tubes: 4, 8 or 12 singlemode optical fibres in PBT loose tubes filled with thixotropic compound. Colour coding of tubes and fibres according to tables 1 and 2. • Core formation: Loose tubes stranded in SZ. Sweallable yarns and tapes to avoid water penetration and make the cable waterproof. • Inner sheath: Fire retardant thermoplastic, low smoke emission and halogen free. • Reinforcement: Aramid yarns as reinforcing element. • Armour: Longitudinal copolymer steel armour, corrugated and rodent resistant. • Outer sheath: Black fire retardant thermoplastic, low smoke emission and halogen free. • Sheath marking : The cable sheath will be marked with white ink at regular intervals with the following information : o CABLESCOM/year/No.fibres/Batch number/singlemode fibre MN/sheath type /length markings/ADIF o Other sheath marks available upon request OPTICAL FIBRE CHARACTERISTICS The parameters of the optical fibres are compliant with the ITU-T G.652D recommendation.
