These direct attach Flyover® SFP/QSFP/OSFP cable assemblies route critical high-speed signals through Eye Speed® ultra low skew twinax for improved and extended signal integrity.
Family Overview
Samtec’s Flyover® SFP/QSFP/OSFP 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.
Features
Samtec’s proprietary co-extruded, low loss Eye Speed® cable technology eliminates the performance limitations and inconsistencies of individually extruded dielectric twinax cabling, improving signal integrity, bandwidth and reach.
Samtec’s Flyover® designs provide end option flexibility to create a high-speed application specific solution to meet next gen speeds. Flyover® SFP/QSFP/OSFP systems have many End 2 options, including:
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 SI Evaluation Kits provide system designers and SI engineers an easy-to-use solution for testing FQSFP Product Flyover® QSFP28 Cable System with various End 2 options. The FQSFP to AcceleRate® Flyover® SI Evaluation Kit (REF-205303-X.XX-XX) routes eight high-speed differential pairs through high-precision RF connectors, the FQSFP to AcceleRate® cable assembly and PCB-mount connectors. The FQSFP Evaluation Kits deliver high-quality systems with robust mechanical design. Please contact Samtec’s technical experts at KitsAndBoards@samtec.com for additional information.
