FireFly™ Low-Profile Micro Flyover® Assemblies

Samtec ECUE FireFly™ Low-Profile Micro Flyover® Assemblies are a copper solution based on Samtec’s 100Ω 34AWG and 36AWG Twinax ribbon cable. These assemblies are interchangeable with a FireFly optical assembly using the same connector system. Samtec ECUE FireFly Low-Profile Micro Flyover Assemblies feature 28Gbps performance, a 3.18mm (0.125") bend radius, and a wide variety of End 2 options. The Eye Speed® cables are offered in 36AWG Twinax, 34AWG Twinax, and 34AWG ultra-low skew Twinax in lengths ranging from 150mm to 1000mm. These ECUE components are designed for onboard or on-package placement.
