Samtec's Flyover® cable technology can help increase signal reach and density to achieve next-generation speeds by routing signals over ultra-low offset twinax cable rather than a lossy PCB.
As bandwidth requirements rapidly increase, Flyover® systems break through the limitations of traditional signaling substrates and hardware offerings, resulting in a cost-effective, high-performance and thermally efficient answer to the challenges of 224 Gbps bandwidths and beyond.
Samtec's flyover design provides the flexibility to develop an application-specific high-speed solution for the next generation of speeds.
