The JBX05574 4-meter HPE Q9S72A-4M compatible 100GBASE-CR4 QSFP28 to 4x SFP28 direct attach copper (DAC) breakout cable represents an enterprise-grade solution for high-speed data center networking. Engineered to replace HPE OEM part numbers Q9S72A-4M and 845416-B21-4M, this passive breakout DAC cable delivers exceptional performance without active signal regeneration, resulting in lower power consumption and reduced latency compared to active alternatives. Technical Excellence: Built with precision 26AWG twinax copper conductors and durable plastic jacketing, this cable achieves 100GB data transmission speeds across 4 meters. The QSFP28 male connector interfaces with standard QSFP28 ports, while four integrated SFP28 connectors enable direct connection to SFP28-equipped network interface cards or switch ports. The design adheres to IEEE 802.3bj specifications and QSFP28 MSA standards, ensuring seamless interoperability with HPE infrastructure. Compliance & Safety: This cable maintains full RoHS and ELV compliance under EU Directive 2002/95/EC, with additional TUV and UL safety certifications. These credentials guarantee reliability, environmental responsibility, and adherence to international safety standards. Practical Applications: Ideal for enterprise data centers, cloud infrastructure, and high-performance computing environments where cost-effective 100GB connectivity is essential. The breakout configuration eliminates the need for multiple single cables, streamlining cable management and reducing deployment complexity. Reliability & Support: Operating reliably across 0-70°C temperature ranges, backed by a 90-day limited warranty and U.S.-based shipping from Danville, CA and Beaufort, SC. Custom brand programming available for white-label requirements. Free standard shipping on orders exceeding $99 makes this solution budget-friendly for infrastructure upgrades and expansions.
