The JBX06056 4-meter SFP+ passive direct attach copper cable represents a superior connectivity solution for organizations requiring high-speed, low-latency network infrastructure. Specifically engineered for Intel-compatible systems, this cable delivers robust 10GBASE-CR performance at a fraction of the cost of active alternatives. Key Technical Features: This passive DAC cable utilizes 24AWG twinax copper conductors with professional-grade plastic jacketing, providing optimal signal integrity for 10GB data transmission. At 4 meters in length, it accommodates typical data center rack-to-rack connectivity requirements while maintaining performance standards. The cable achieves full compliance with IEEE 802.3ae specifications and SFF-8431/SFF-8472 standards, ensuring compatibility across enterprise networking equipment. Performance & Reliability: As a passive design, the JBX06056 requires no external power, reducing energy consumption and eliminating potential points of failure associated with active electronics. The dual SFP+ connectors feature precision-engineered copper contacts, delivering secure connections resistant to oxidation and corrosion. Operating across a 0-70°C temperature range accommodates both standard and warm data center environments. Compliance & Certifications: Fully RoHS/ELV compliant and certified to TUV and UL standards, this cable meets stringent regulatory requirements for enterprise deployments. The EU directive 2002/95/EC compliance ensures environmental responsibility without compromising performance. Intel Compatibility & Replacement: Designed as a direct replacement for Intel OEM part number XDACBL4M, the JBX06056 provides guaranteed compatibility with Intel networking equipment while offering superior value. Custom brand programming is available for organizations requiring white-label solutions. Practical Applications: Ideal for server-to-switch connectivity, storage area networks (SANs), switch stacking, and high-speed interconnects within data center environments. The 4-meter length bridges typical aisle distances without requiring longer, more expensive cabling solutions. Value & Support: With a 90-day limited warranty and expedited shipping from US locations (Danville, CA and Beaufort, SC), the JBX06056 delivers professional reliability backed by responsive support. Free standard shipping on orders exceeding $99 further enhances overall value.
