FIBEROPTIC

External Aerial Fiber Optic Armoured Cable GYTA 24B1.3

The 250μm fiber is positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The parallel steel wires are placed at the two sides tape. The cable is completed with a polyethylene (PE) sheath.
