Helping Supercomputers Think Faster

Rosendahl’s High-Temperature Foam Lines for Twinax Cables Set the Global Benchmark for Precision and Performance in AI Cable Infrastructure.

Data transmission rates reaching terabytes per second. Extremely low latency. High temperature resistance. These are the key reasons Twinax cables are used in AI data centres, where they connect thousands of GPUs over short distances.

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 of that requires utmost precision and process stability, pushing conventional manufacturing methods to their limits.

High-Temperature Foaming Making It Happen

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, during which 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 centres.

Looking ahead, Rosendahl continues to push the boundaries of what’s 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.
