The JBX05519 represents a premium solution for modern data center infrastructure requirements. As a direct drop-in replacement for Arista's CAB-Q-2Q-100G-3M, this 100GBASE-CR2 QSFP28 breakout cable delivers uncompromised performance in high-density networking environments. **Technical Excellence:** Built to IEEE 802.3bj specifications and QSFP28 MSA standards, this cable supports full 100GB/s throughput without requiring active components or power supplies. The 26AWG twinax copper construction provides superior signal integrity while maintaining flexibility for installation in tight rack spaces. Dual QSFP28 connectors enable efficient breakout configurations, allowing single 100G ports to split into dual 50G connections when needed. **Quality Assurance & Compliance:** Manufactured to stringent international standards including RoHS/ELV directive 2002/95/EC compliance, TUV certification, and UL listing. These certifications ensure the cable meets environmental regulations while maintaining electromagnetic compatibility in diverse data center deployments. The 90-day limited warranty provides additional peace of mind for enterprise customers. **Installation & Performance:** The 3-meter length provides optimal distance for standard rack-to-rack connections without signal degradation. Operating across 0°C to 70°C temperature range ensures reliable performance in various facility conditions. As a passive solution, there's no latency, no power draw, and zero compatibility headaches—simply connect and operate. **Cost-Effective Networking:** Compared to active optical solutions, this DAC cable offers significant cost savings while delivering identical performance for distances under 10 meters. Ideal for ToR (top-of-rack) switching, storage area networks (SANs), and inter-switch connections where reliability meets budget consciousness. **Custom Branding Available:** Organizations seeking branded cables for standardized deployments can take advantage of custom brand programming options, ensuring consistency across infrastructure investments. Ships from two U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, making this enterprise-grade networking component accessible to organizations of all sizes.
