The JBX05506 Direct Attach Copper (DAC) Cable represents a premium networking solution for organizations requiring high-speed, reliable 10GB connectivity in data center environments. This 4-meter QSFP+ to SFP+ cable delivers excellent performance while maintaining cost-effectiveness compared to active optical alternatives. Key Features & Specifications: This passive DAC cable employs 28AWG twinax copper conductors with protective plastic jacketing, engineered to transmit low-voltage network signals with minimal signal degradation. The QSFP+ to SFP+ connector architecture provides flexible connectivity options for mixed-speed networking environments. Operating across a wide temperature range (0-70°C), the cable maintains consistent performance in various deployment scenarios. Compatibility & Standards: Fully compatible with NVIDIA Mellanox switching and networking infrastructure, this cable directly replaces OEM part MC2309124-004. The 10GBASE-CR standard enables seamless integration into existing enterprise networks. RoHS and ELV directive compliance ensures environmental responsibility and regulatory adherence across global markets. Technical Advantages: As a passive DAC solution, this cable eliminates the need for active electronics, reducing power consumption and operational complexity. The short 4-meter length makes it ideal for top-of-rack (TOR) switching, intra-cabinet connections, and short-distance data center deployments. The copper construction provides superior conductivity and durability compared to inferior alternatives. Use Cases: Ideal for data centers, enterprise networking, high-performance computing clusters, and storage area networks (SANs) requiring cost-effective 10GB interconnectivity. Perfect for organizations standardizing on NVIDIA Mellanox infrastructure seeking OEM-compatible replacement cables. Warranty & Support: Backed by a comprehensive 90-day limited warranty, with shipping from strategically located US warehouses (Danville, CA and Beaufort, SC) ensuring rapid delivery. Free standard shipping on qualifying orders provides exceptional value for bulk purchases and deployment projects.
