The JBX05310 5m HPE Aruba Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents an excellent solution for enterprise organizations seeking cost-effective, high-speed data center connectivity. This professional-grade networking cable is specifically engineered to deliver 40Gbps throughput while maintaining exceptional signal integrity over its 5-meter span. Technical Excellence and Compatibility: Built with 28AWG twinax copper conductors and protected by durable plastic jacketing, this cable meets rigorous industry standards. It is fully qualified to IEEE 802.3ba specifications and carries QSFP+ connectors on both ends, ensuring seamless integration with HPE Aruba switches, routers, and network equipment. The passive design eliminates active electronics, reducing power consumption and potential points of failure in mission-critical network infrastructure. Key Features and Benefits: This DAC cable offers several compelling advantages for data center and enterprise network environments. The passive architecture requires no external power, lowering operational costs and cooling requirements. At 5 meters, it provides flexibility for equipment placement without the signal degradation common in longer copper runs. The twinax construction delivers superior electromagnetic shielding, ensuring reliable performance in electrically noisy environments. Custom brand programming is available for organizations requiring OEM labeling. Compliance and Reliability: Fully RoHS and ELV compliant, this cable meets EU directive 2002/95/EC standards, making it suitable for regulated environments. TUV and UL certifications confirm adherence to strict safety protocols. A 90-day limited warranty provides additional peace of mind. Operating temperature range of 0 to 70°C (32 to 158°F) ensures performance across diverse data center climates. Ideal Applications: Perfect for direct server-to-switch connections, switch-to-switch trunking, and storage area network (SAN) implementations where 40Gbps speeds are required. The 5-meter length accommodates mid-range equipment spacing without introducing latency or signal loss. Organizations migrating from slower 10GbE or 25GbE infrastructure will appreciate the performance upgrade, while those standardizing on HPE Aruba platforms benefit from certified compatibility. Value Proposition: Compared to active optical cables or longer copper runs, passive DAC cables offer superior value through lower cost, reduced power consumption, and simplified deployment. Free standard shipping on orders exceeding $99, combined with rapid fulfillment from dual US locations, ensures quick project completion and minimal downtime.
