Direct buried steel tape armoured cable is available in fiber optic, loose tube, Flextube, unitube, and spiral space product families. Uses steel tape armoring for maximum crush resistance.
Good insulativity and shielding effectiveness to reduce attenuation, complying with RoHS standard.
The fiber ribbons, single-mode type, are positioned in the slotted core made of HDPE.
A steel wire or steel rope locates in the center of core as a metallic strength member. The slotted core is wrapped with waterproof tape helical.
Over the waterproof tape, an APL (Aluminium Polyethylene Laminate) is applied longitudinally. Then the cable is completed with a polyethylene (PE) sheath. A rip cord is placed between the APL and the waterproof tape in order to rip the cable easily.
