The JBX05467 3-meter Cisco-compatible 40GBASE-CR4 QSFP+ active direct attach copper cable represents a cost-effective solution for building high-speed, reliable network infrastructures in modern data centers and enterprise environments. **Superior Design and Construction** This active DAC cable utilizes premium 30AWG twinax copper conductors engineered to maintain signal integrity over its 3-meter length. The robust plastic jacketing provides mechanical protection while maintaining flexibility for installation in tight spaces. The active electronics embedded within the cable enable extended reach compared to passive alternatives, making it ideal for complex network topologies. **Technical Specifications** Fully qualified to IEEE 802.3ba standards, this cable supports 40 gigabit per second data rates with minimal latency. Operating across a temperature range of 0-70°C (32-158°F), it performs reliably in various environmental conditions. The QSFP+ to QSFP+ connector configuration ensures seamless compatibility with Cisco switching equipment and supported third-party infrastructure. **Compliance and Certification** Manufactured to stringent RoHS and EU directive 2002/95/EC standards, this cable meets international environmental regulations. TUV and UL certifications confirm adherence to safety and performance standards, providing confidence for mission-critical deployments. **Ideal Applications** Perfect for server-to-switch connectivity, storage area networks (SANs), data center backbone infrastructure, and high-frequency trading environments. The 3-meter length accommodates standard rack-to-rack configurations without excessive cable runs. **Value and Support** Includes a 90-day limited warranty and ships from strategic US locations (Danville, CA and Beaufort, SC) for rapid delivery. Custom brand programming is available for enterprise customers requiring OEM labeling. Ships free with orders over $99. **Cost-Effective Alternative** Offers substantial savings compared to optical solutions while maintaining comparable performance for shorter distances, making it the preferred choice for cost-conscious network administrators deploying 40GB infrastructure.
