4X - 4X InfiniBand assemblies with ejectors provide secure, serviceable connections for high performance cluster and storage interconnects. Configurations include shielded copper and optical cable assemblies with integrated ejector mechanisms for positive mating and easy removal. Cable options support DDR and higher data rates, and are specified for minimal crosstalk and consistent signal integrity across short and medium distances. These assemblies are intended for rack and chassis deployments where reliable connectors and fast serviceability are required.
