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
- Low skew (< 3.5 ps/meter) over extended lengths
ULTRA LOW SKEW CABLE TECHNOLOGY
Dynamic Testing
Ultra low skew twinax cable underwent Dynamic Insertion and Return Loss testing, proving the cable to be rugged with stable electrical performance after 250 flex/bend cycles.
Cable Management
Samtec works with system architects in the early stages to optimize architecture for cable management while keeping signal integrity and thermals in mind.

FLYOVER QSFP28 CABLE SYSTEMS
Samtec’s Flyover QSFP Systems provide improved signal integrity and architectural flexibility by flying critical high-speed signals over lossy PCB materials and directly to the panel via ultra low skew twinax cable. The ultra-high-density design includes sideband signaling via press-fit contacts to help increase airflow, and a multitude of “End 2” options allow for maximum design flexibility.
Flyover QSFP
- 4 channels (x4 bidirectional, 8 differential pairs)
- ~100 Gbps NRZ aggregate (~200 Gbps PAM4)
- Compatible with all QSFP assemblies
Double Density Flyover QSFP
- 8 channels (x8 bidirectional, 16 differential pairs)
- ~200 Gbps NRZ aggregate (~400 Gbps PAM4)
- Belly-to-Belly mating for maximum density
- Backward compatible with QSFP modules
- Localized press-fit control and power contacts eliminate the need for a secondary cable and connector
- Sideband signals are routed through press-fit contacts for increased airflow
DIRECT ATTACH
- One or two rows of contacts directly soldered to the cable
- Improved signal integrity by eliminating transition board and its variability
- Achieves tighter tolerances
ULTRA LOW SKEW TWINAX
- Ideal for 28-56+ Gbps applications
- Tight coupling between signal conductors
