Twinax Cables, Samtec Flyover® Systems for Next Gen Speeds
Twinax Cables, Samtec Flyover® Systems for Next Gen Speeds
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.
OVERVIEW
(-5 dB Loss Target, Reach Estimate. For OIF VSR applications.)
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.
FEATURES
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.
Ultra Low Skew Twinax
- 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
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. Click here to learn more or contact HDR@samtec.com for higher cycle results.
Cable Management
Samtec works with system architects in the early stages of design to create solutions for cable management optimized for signal integrity and even distribution of thermal load. Contact HDR@samtec.com for more information.
