Outdoor Double Jacket Steel Armoured Figure 8 Aerial Fiber Optic Cable

The fiber, either single mode or multimode type, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A fibre-reinforced plastic (FRP), sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core, enclosed by an inner polyethylene (PE) jacket. The cable core is filled with filling compound to protect it from water. A corrugated steel tape armour(CST) is longitudinally applied over the inner jacket. The cable is completed with a Polyethylene (PE) sheath.

Double armoured version can be achieved by adding a layer of aluminium tape armour before the inner jacket.
