High-Density Computing Advantages

Impedance-Stable Bending

Our patented structure ensures that even under extreme 180° folds, the signal impedance remains stable for Gen.4 speeds.

Improved Airflow

The 1.25mm profile significantly reduces cable bulk, optimizing cooling paths in high-density AI server racks.

Zero-Latency Passive Path

By eliminating the need for EQ chips or repeaters, we provide a pure signal path with the lowest possible latency.

Enterprise Reliability

Rigorous signal integrity testing ensures no CRC errors even during continuous high-load data center workloads.
