The JBX05670 4m Dell Compatible 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents a cost-effective, high-performance solution for modern data center networking infrastructure. As passive DAC technology continues to dominate enterprise connectivity solutions, this cable delivers exceptional value and reliability. Technical Specifications: This QSFP28 DAC cable features 26AWG twinax copper conductors with plastic jacketing, providing optimal performance for 100GB Ethernet applications. The passive design eliminates the need for active electronics, reducing power consumption, heat dissipation, and potential points of failure. Operating temperature specifications of 0-70°C (32-158°F) ensure compatibility with standard data center environmental conditions. Compliance & Standards: Fully qualified to IEEE 802.3bj specifications and QSFP28 Multi-Source Agreement (MSA) standards, this cable meets or exceeds industry requirements. RoHS/ELV and EU Directive 2002/95/EC compliance ensures environmental responsibility and regulatory adherence. TUV and UL safety certifications provide additional assurance of product quality and reliability. Performance Advantages: Passive DAC technology delivers superior performance compared to active optical alternatives for short-distance interconnects (under 5 meters). The twinax copper construction minimizes signal degradation and latency, making it ideal for latency-sensitive applications. The 4-meter length provides flexibility in rack and switch placement while maintaining signal integrity. Applications: Ideal for: • Data center switch-to-server connections • High-performance computing cluster interconnects • Virtualized infrastructure deployments • Storage area network (SAN) implementations • Cloud computing environments Compatibility: Direct compatibility with Dell networking equipment supporting QSFP28 100GBASE-CR4 connections.
