High-temperature foaming making it happen
Data transmission rates reaching terabytes per second. Extremely low latency. High temperature-resistance. These are the key reasons Twinax cables are used in AI datacenters where they connect thousands of GPUs over short distances. To achieve the high performance needed for supercomputers, nothing can be left to chance in manufacturing. Otherwise, performance is already affected. These strict demands push conventional manufacturing methods to their limits.
Leading cable manufacturers worldwide rely on our high-temperature foam lines for Twinax cable insulation, setting the international standard for precision and performance in AI cable infrastructure.
Cables manufactured on ourequipment already achieve transmission speeds of terabytes per second between the “brain cells” of AI systems. And we’re not stopping there—our research and development teams are already working on solutions for even higher transmission rates.
Did you know that currently up to 30% of computer time (and energy) is lost due to signal latency of the cables?
Data transmission is only as fast as the cables and connections allow. That means that by upgrading to higher-performance cables, data centers can accelerate existing AI systems. Without the need to upgrade processors or other hardware.
3 critical production factors for Twinax cables
Excellent geometry
Precise conductor center positioning, ovality and diameter with very tight tolerances require the utmost process stability.
Conductor pitch
The distance between the two conductors must remain consistent. Any variation affects signal propagation.
Foam
quality
A uniform foam structure is essential for consistent capacitance and impedance. It reduces signal attenuation and improves the electrical properties of the cable.
