FLYOVER QSFP CABLE ASSEMBLIES FEATURES & BENEFITS QSFP28, QSFP-DD and QSFP-D8 systems utilize Samtec Flyover technology to route data above lossy PCB, simplifying board layout and extending signal reach. The modular design enables optimized systems that improve heat management, increase signal integrity performance, build in scalability for future upgrades and reduces costs by creating a multifunction board.
