Thin Wall Aluminum Layered FIMT

An OPPC and OPGW Fiber Optic Cable

The Thin Wall Aluminum Layered FIMT (ACT) performs even in harsh climate conditions, including the Oil & Gas Industry. An outer aluminum sheath protects the configuration from potentially threatening external influences, such as wind, ice, and rain. The aluminum layer is between 0.25 mm and 0.3 mm, making the cable simultaneously durable and lightweight, ideal for power lines.

The stainless-steel tube protects the optical fibers from mechanical stress. In addition, the aluminum layer protects against hydrogen and prevents galvanic corrosion within the cable, which is a common cause of OPGW failure. We produce the fiber optic cable with up to 92 optical fibers at an OD of 250μm, and the durable OPPC & OPGW fiber optic cable still weighs as little as 20 kg/km.

We manufacture our products according to the highest industry standards. By approaching every challenge uniquely, we find the best solution for each project. Contact us today and speak to one of our experts if you feel like the Thin Wall Aluminum Layered FIMT could be the solution for you.
