Rosendahl’s high-temperature foam lines for “Twinax” cables set the global benchmark for precision and performance in AI cable infrastructure. To achieve the high performance needed for supercomputers, nothing can be left to chance in cable manufacturing.

The product geometry must stay within extremely tight tolerance ranges. The two conductors in the “Twinax” cable must remain perfectly parallel; even slight deviations can impact performance.

Additionally, a uniform foam structure is crucial for maintaining consistent capacitance and impedance. This reduces signal attenuation and enhances the electrical properties of the cable.  All that requires utmost precision and process stability, pushing conventional manufacturing methods to their limits.

High-temperature foaming
Leading data cable manufacturers worldwide trust Rosendahl’s high-temperature foam lines to achieve exceptional “Twinax” cable insulation. This trust is built on years of expertise, where Rosendahl’s extrusion specialists have developed finely tuned equipment and advanced process know-how for cables with superior properties.

Today, this technology enables transmission speeds of terabytes per second, seamlessly connecting the "brain cells" of AI systems and driving the performance of modern data centers.

Looking ahead, Rosendahl continues to push the boundaries of what is possible in cable manufacturing. The company remains dedicated to innovation and collaborates closely with industry partners to meet the evolving demands of AI and next-generation supercomputers.
