The JBX06254 10GBASE-CR SFP+ passive Direct Attach Copper cable represents an excellent choice for organizations requiring cost-effective, high-speed network connectivity without sacrificing performance. This 2.5-meter cable bridges the gap between network switches, servers, and storage devices in data center environments, offering a practical alternative to fiber optic solutions for short-distance applications. **Technical Specifications & Construction** Built to SFF-8431 specifications, this passive DAC cable features SFP+ connectors on both ends and utilizes 30AWG twinax copper conductors wrapped in protective plastic jacketing. The dual copper design ensures minimal signal loss, electromagnetic interference protection, and consistent performance over the full 2.5-meter length. Unlike active DAC cables, the passive design eliminates powered components, reducing potential points of failure. **Performance & Compatibility** Qualified for 10GBASE-CR standard transmission, this cable delivers reliable 10GB Ethernet speeds ideal for demanding network architectures. Full Intel compatibility ensures seamless integration with Intel-based switching infrastructure and network interface cards. The cable meets or exceeds IEEE standards SFF-8431 and SFF-8472, guaranteeing interoperability across certified network equipment. **Environmental Compliance & Safety** Fully RoHS and ELV compliant per EU directive 2002/95/EC, this cable meets stringent environmental standards. It carries TUV and UL safety certifications, assuring quality and reliability for enterprise deployments. Operating temperature range of 0-70°C (32-158°F) accommodates diverse data center environments. **Practical Applications** Ideal for server-to-switch connections, storage area networks (SANs), and inter-switch links, this cable delivers the performance needed for today's bandwidth-intensive applications. Organizations can reduce infrastructure costs by utilizing passive DAC cables for predetermined, short-run connections while reserving fiber solutions for longer distances. **Warranty & Support** Each cable includes a 90-day limited warranty and ships from strategically located US distribution centers. Free standard shipping applies to orders exceeding $99, making this solution cost-effective for both individual purchases and bulk deployments.
