Unless otherwise approved in writing by Samtec, all parts and components are designed and built according to Samtec’s specifications which are subject to change without notice.
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.
