Application |
Standards |
|
This cable can be used for LAN and WAN system backbones, telecommunications connection lines, FTTB (fiber to the business, fiber to the building) connection lines, same as for FTTH (fiber to the home) house connections. Fire-resistant, watertight and UV-resistant sheath makes it ideal for mixed indoor and outdoor installations. Can be laid in cable canals and on trays. Can be installed in tubes by blow in-procedure. Glass fibers provide resistance to tensile strains (specially versions for 1,5 and 3,0 kN) and to a certain degree serve as anti-rodent protection. Versions for 1,5 and 3,0 kN can be laid directly in ground, with adequate sand bedding. |
