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. Watertight and UV-resistant sheath of LLDPE enables outdoor installation in not too hard conditions. 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 and to a certain degree serve as anti-rodent protection. Cable suitable for direct laying in ground, with adequate sand bedding. |
