Family Overview


Samtec Flyover® systems can help extend signal reach and density to achieve next gen speeds by routing signals via ultra-low skew twinax cable versus through lossy PCB.

THE PROBLEM: PCB REACH AT NEXT GEN SPEEDS


As bandwidth requirements rapidly increase, effectively managing heat and routing signals through lossy PCBs, vias and other components have become complex challenges.

THE SOLUTION: SAMTEC FLYOVER® SYSTEMS


Samtec Flyover® design breaks the constraints of traditional signaling substrate and hardware offerings, resulting in a cost–effective, high-performance and heat efficient answer to the challenges of 56 Gbps bandwidths and beyond.

ULTRA LOW SKEW CABLE TECHNOLOGY


Samtec's proprietary co-extruded Eye Speed® twinax cable technology eliminates the performance limitations and inconsistencies of individually extruded dielectric twinax cabling; improving signal integrity, bandwidth and reach for high-performance system architectures. 

  • Ideal for 28-112+ Gbps applications
  • Tight coupling between signal conductors
  • Improved bandwidth and reach
  • Improved signal integrity and eye pattern opening
