Cable Application (Indoor cables)
Cable can be designated as Indoor (non-metallic) cable. Cable can be installed by pulling or air blown in indoor ducts or micro-ducts or on cable trays. Fiber Optic cables are cables are used for triple-play (Voice-video-data), FTTx applications in telecommunication projects, long-haul, backbone, metropolitan, broadband, utility and intelligent traffic control, supervisory control and data acquisition (SCADA), cable TV (CATV), military, etc.
Indoor cable – Jelly filled loose tube/filler elements are stranded around a dielectric central strength member (FRP) by reverse oscillation lay (SZ) method, cable core protected from water penetration inside the core by water blocking tape/yarns, glass yarns provided for extra tensile strength under (or) over water blocking tape and outer sheath of Halogen Free Flame Retardant (HFFR/LSZH).
