FQSFP-D8 SI Evaluation Kits

REF-228441-X.XX-XX

Company: Samtec

As data rates increase, trace length on PCBs decrease. Samtec's high-speed, Flyover® cable assemblies simplify PCB design and limit signal degradation in high data rate applications. The FQSFP-D8 SI Evaluation Kits provide system designers and SI engineers an easy-to-use solution for testing FQSFP-D8 Product 800G Flyover® QSFP Double Density Cable System with various End 2 options. The FQSFP-D8 to NovaRay® Flyover® SI Evaluation Kit (REF-228441-X.XX-XX) routes sixteen high-speed differential pairs through high-precision RF connectors, the FQSFP-D8 to NovaRay® cable assembly and PCB-mount connectors. The FQSFP-D8 to Si-Fly® Flyover® SI Evaluation Kit (REF-226551-X.XX-XX) routes sixteen high-speed differential pairs through high-precision RF connectors, the FQSFP-D8 to Si-Fly® Low-Profile, High-Density Interconnect System. The FQSFP-D8 SI Evaluation Kits deliver high-quality systems with robust mechanical design. Please contact Samtec's technical experts at [email protected] for additional information.

Country of Origin (“COO”) Information
Probable COO: UNITED STATES. For quantity-specific COO data, please use our pricing & delivery lookup tool. Probable Country of Origin is our best effort to predict the COO. However, due to our Sudden Service and order flexibility, the Country of Origin is subject to change. If the COO at shipment changes from the latest Order Acknowledgement, Samtec will pass along the lesser of the two tariff surcharge rates.
