The JBX06219 HPE ProCurve 10GBASE-CR SFP+ Passive Direct Attach Copper Cable represents a professional-grade networking solution designed specifically for high-speed data center environments and enterprise infrastructure deployments. This 1-meter twinax cable combines reliability, performance, and cost-effectiveness in a single integrated package. **Technical Specifications & Performance:** Constructed with 30AWG twinax copper conductors and protected by durable plastic jacketing, this passive DAC cable achieves full 10 gigabit-per-second data transmission rates without requiring external power. The cable meets rigorous IEEE 802.3ae, SFF-8431, and SFF-8472 standards, ensuring compatibility across diverse networking ecosystems. Operating temperature range of 0-70°C (32-158°F) provides flexibility for varied deployment scenarios from server rooms to outdoor telecommunications enclosures. **Compatibility & Integration:** Specifically engineered for HPE ProCurve infrastructure, this cable serves as a perfect replacement for OEM part numbers J9281B and J9281D. Its SFP+ duplex connectivity ensures seamless integration with existing switches, servers, and networking equipment featuring standard SFP+ ports. The passive design eliminates compatibility concerns associated with active optical cables while reducing total cost of ownership. **Quality Assurance & Compliance:** Fully compliant with EU RoHS (2002/95/EC) and ELV directives, this cable meets stringent environmental and safety requirements. TUV and UL certifications provide additional assurance of manufacturing quality and safety standards. Each cable includes a 90-day limited warranty protecting your infrastructure investment. **Applications & Use Cases:** Ideal for server-to-switch connectivity in data centers, this cable excels in high-density rack deployments where active cable limitations prove prohibitive. Perfect for virtualization environments, storage area networks (SANs), and enterprise backbone infrastructure. The compact 1-meter length accommodates typical top-of-rack (ToR) and end-of-row (EoR) switch architectures while maintaining cable management efficiency. **Practical Benefits:** Passive DAC technology eliminates power consumption and associated heat generation, reducing cooling requirements in dense deployments. The straightforward copper twinax construction provides superior EMI immunity compared to optical alternatives. Free standard shipping on orders over $99 makes this an economical choice for volume infrastructure upgrades. Whether upgrading legacy HPE ProCurve networks or deploying new high-speed infrastructure, the JBX06219 delivers reliable 10GB connectivity backed by established compatibility and comprehensive quality certifications.
