STANDARDS Cable construction: DGT standard Fibres: ITU-T G652 D. DESCRIPTION AND APPLICATION Loose tube single mode optical fibre cables with a double PE sheath and armoured with a corrugated steel tape for mechanical and rodent's protection. These cables can be installed in underground ducts or directly buried. CONSTRUCTION • Central reinforcing element: Dielectric fibreglass (FRP). • Loose tubes: PBT loose tubes filled with thixotropic compound and containing single mode optical fibres according to ITU-T G.652 D. 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: polyethylene. • Armouring: Corrugated copolymer coated steel tape longitudinally applied with overlap. • Outer jacket: Black UV resistant polyethylene. • Sheath marking : The cable sheath will be marked with white ink at regular intervals with the following information : o CABLESCOM / year / Number of fibres MN/ PSP / batch number +length markings 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. See our fibre product sheet for the characteristics of the fibre_ Optical transmission characteristics of cabled fibre: Attenuation coefficient: Average / maximum at 1310 nm: 0,36 / 0,38 dB/km Average / maximum at 1550 nm: 0,22 / 0,25 dB/km PMD < 0,20 ps/km1/2 PMD link < 0,10 ps/km1/2 Cut-off wavelength (Ac) < 1260nm All drawings, designs, specifications and particulars of weights, dimensions, etc. in this documentation are only indicative and must not be considered contractual.
