Flyover QSFP28 Cable Systems

Direct attach flyover QSFP28 cable assemblies fly critical high-speed signals over the PCB for improved and extended signal integrity.


FAMILY OVERVIEW

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.

FEATURES

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
  • 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
  • Samtec's Flyover Systems

Samtec’s flyover designs provide end option flexibility to create a high-speed application specific solution to meet next gen speeds. Flyover QSFP28 has many End 2 options, including:
