Cable consisting of singlemode optical fiber and/or multimode optical fiber with acrylate coating. The tubes containing optical fibers is filled with thixotropic loose tube filling compound to ensure the optical fiber protection. The stranded tubes can be dry (containing waterblocking elements) or jelly filled (jelly filling compound) in order to prevent water penetration. The stranded tubes are surrounded and sheathed with black polyethylene. Over the inner sheath it is applied longitudinally a corrugated steel armour covered, ensuring protection against rodents and termites, with an external jacket of black polyethylene.
