Cables are exposed to very high tensile forces during installation and often also during operation. If the tensile load capacity is just sufficient for the installation, the forces acting on the cable can increase the fibre elongation. This means greater stress and thus a shortened fibre service life. To counteract this, the Multimedia Solutions (MMS) BU of the Prysmian Group has extremely tensile and compact fibre optic central bundle cables in its portfolio.
The gel-filled non-metallic cable types E08a, E10a, E20, E22 and E25 have a tensile strength of 3,000 N. The non-metallic cable type E09a can even withstand loads of up to 4,000 N, the two cable models E14a and E16a 2,000 N. Thanks to improved production technologies, MMS has achieved that the central loose tube cables E08a, E10a, E20, E22 and E25 have the same tube diameter for 24 fibres as for 2 fibres. The cable diameter for 24-fibre cables has thus been greatly reduced. The cables are very compact. The high tensile strength with reduced diameters brings users double benefits.
The metal-reinforced cable versions E06a, E07a, E19 and E21 also have a tensile strength of 3,000 N.
Application range of the central loose tube cables
The universal fibre optic cables E07a, E10a, E14a, E19, E20, E21, E22 and E25 with central loose tube are used as house entry cables for duct laying, LAN communication and as indoor riser cables. The fibre optic outdoor cables E06a, E08 and E09a are used in the primary area (campus backbone) and in TC backbones. All cables meet the requirements of ISO 118011, EN 50173-1:2002, IEC 60794-1, TIA GR20, ICEA 640 and ICEA 696. The design of the central tube enables a cost-effective and thin cable construction. The cables are UV-resistant, waterproof, rodent-proof, halogen-free and flame-retardant, making them equally suitable for indoor and outdoor use. With the central loose tube cables, users receive excellent quality in a compact design at a reasonable price and thus the highest investment protection.
