The JBX05267 10-meter Ruckus compatible 40GBASE-CR4 QSFP+ Active Direct Attach Copper Cable represents a sophisticated solution for modern data center infrastructure. This high-performance cable combines cutting-edge active technology with proven copper connectivity to deliver exceptional value and reliability. **Technical Excellence** Designed to IEEE 802.3ba and SFF-8436 standards, this cable supports 40 Gigabit Ethernet transmission with zero compromise on signal integrity. The 28AWG twinax copper construction provides optimal impedance matching and minimal signal loss over the 10-meter span, making it ideal for short-to-medium distance interconnections within data centers and server rooms. **Active DAC Advantage** Unlike passive DAC cables, the active design incorporates signal conditioning circuitry that extends cable reach while maintaining superior performance characteristics. This eliminates the cost, power consumption, and heat generation associated with optical transceiver solutions, delivering a true total-cost-of-ownership advantage. **Enterprise-Grade Compliance** Fully RoHS and ELV compliant per EU Directive 2002/95/EC, with TUV and UL certifications, this cable meets the strictest environmental and safety standards. The robust plastic jacketing protects against physical damage while maintaining flexibility for installation in tight spaces. **Seamless Ruckus Integration** Precisely engineered for Ruckus switch compatibility, this cable replaces OEM part number E40G-QSFP-QSFP-C-1001, ensuring perfect fit and function within your existing infrastructure. QSFP+ to QSFP+ copper connectors guarantee secure, reliable connections every time. **Operational Reliability** With a wide operating temperature range of 0 to 70°C (32 to 158°F), this cable performs consistently in diverse data center environments. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 enhances accessibility. Ships from strategically located distribution centers in Danville, CA and Beaufort, SC for rapid delivery. **Perfect Applications** Ideal for connecting Ruckus switches to servers, storage arrays, and networking equipment in enterprise, cloud, and colocation data centers. The active DAC technology particularly benefits configurations requiring reliability without optical complexity.
