As non-metallic composites, Aramid Reinforcement Plastic (ARP) Rods are designed and used as strength members in fiber-optics. The entire concept of having cable-reinforcement-solutions hinges on providing optical fibers in the cables with protection against mechanical stresses, which is instrumental to have optimal performance from them. ARP Rods work as truly efficient cable-reinforcement-solutions, that are usually fitted at the centre or in the periphery of the cables.
