The Steelnet OTDr D is a specialized optical cable designed for demanding industrial and infrastructure connections. It features a core of 12 fibers, providing the necessary capacity for high-speed data transmission across critical network links. To ensure reliability in harsh environments, the cable is built to withstand a tensile strength of 3.5 kN, which protects the internal fibers from stretching or breaking during installation or under physical stress. This makes it a dependable choice for technicians and engineers who need a robust communication line capable of enduring the rigors of industrial settings.
