The JBX05050 represents the gold standard in high-speed data center connectivity solutions. This 1.5-meter 400GBASE-CR8 QSFP-DD breakout DAC cable is specifically engineered to meet the demanding requirements of modern hyperscale data centers, cloud providers, and enterprise networks requiring ultra-high bandwidth capacity. **Technical Excellence** Featuring a passive copper-based architecture, this breakout cable eliminates active components that could introduce latency or power consumption concerns. The QSFP-DD primary connector interfaces with four QSFP56 secondary connectors, providing flexible breakout options for complex network topologies. With 30AWG twinax copper construction, the cable delivers optimal signal integrity for reliable 400GB transmission across all lanes. **Compatibility & Integration** Designed specifically for NVIDIA Mellanox infrastructure, this cable replaces OEM part number MCP7F60-W01AR30 and integrates seamlessly with compatible switches, NICs, and networking equipment. Compliance with 400GBASE-CR8, QSFP-DD MSA, and CMIS standards ensures broad ecosystem compatibility. **Quality Assurance** Every cable meets stringent quality benchmarks with RoHS 2002/95/EC compliance and UL/TUV certifications. The robust plastic jacket protects copper conductors from environmental stress, while the compact 1.5-meter length optimizes space utilization in dense rack environments. Operating across 0°C to 70°C temperature range ensures reliability in varied data center conditions. **Practical Applications** Perfect for connecting 400G line cards across multiple 100G ports, facilitating legacy system integration, or enabling flexible port aggregation strategies. Whether upgrading existing infrastructure or deploying new high-performance networks, this passive DAC cable provides immediate cost advantages compared to active solutions. **Warranty & Support** Backed by a 90-day limited warranty and available from strategically located U.S. warehouses with free standard shipping on orders exceeding $99, this cable delivers both performance and convenience.
