The JBX05499 5m Ruckus-compatible 40GBASE-CR4 QSFP+ Active Direct Attach Copper Cable represents a premium interconnect solution for modern data center and enterprise networking infrastructures. This industrial-grade cable combines proven active DAC technology with enterprise-class construction standards to deliver superior performance and reliability. Technical Excellence: Built to IEEE 802.3ba specifications, this cable achieves full 40 gigabit-per-second data rates with minimal signal degradation. The 30AWG twinax copper construction provides optimal impedance matching and reduced crosstalk, while the plastic jacketing protects against environmental stress and mechanical wear. The QSFP+ form factor ensures compatibility with current and legacy Ruckus networking equipment, serving as a direct replacement for OEM part number E40G-QSFP-QSFP-C-0501. Key Advantages: Active DAC technology extends transmission distance beyond passive alternatives while consuming significantly less power than optical transceivers, reducing total cost of ownership. The 5-meter length provides flexibility for typical data center rack configurations and inter-cabinet connections without requiring costly optical infrastructure. Superior reliability comes from RoHS and ELV compliance, plus UL and TUV safety certifications meeting EU directive 2002/95/EC requirements. Perfect For: Data center operators, system integrators, and IT professionals deploying Ruckus network switches and infrastructure. Ideal for bandwidth-intensive applications including high-frequency trading, large-scale data analytics, virtualization environments, and cloud computing deployments. Operational Specifications: Operates reliably across 0-70°C temperature range, accommodating diverse data center climates. Backed by 90-day limited warranty and supported by rapid shipping from US distribution centers in California and South Carolina. Custom brand programming available for enterprise customers requiring OEM integration.
