Samtec’s Flyover® QSFP Systems provide improved signal integrity and architectural flexibility by routing critical high-speed signals through low-loss, ultra low skew twinax cable, instead of through expensive, lossy PCBs. 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.
These direct attach Flyover® QSFP cable assemblies route critical high-speed signals through ultra low skew twinax for improved and extended signal integrity.

- Up to 800 Gbps aggregate (112 Gbps PAM4)
- Belly-to-Belly mating for maximum density
- Backward compatible with QSFP & QSFP-DD modules
- PCIe® 6.0 capable
- 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
- One or two rows of contacts directly soldered to the cable
- Improved signal integrity by eliminating transition board and its variability
- Achieves tighter tolerances
Samtec’s proprietary co-extruded, low loss, twinax cable technology eliminates the performance limitations and inconsistencies of individually extruded dielectric twinax cabling, improving signal integrity, bandwidth and reach.
- Ideal for 28–56+ Gbps applications
- Tight coupling between signal conductors
- Ultra low skew twinax < 3.5 ps/meter
