The JBX04970 3-meter 200GBASE-CR8 QSFP-DD to 2x QSFP28 direct attach copper cable represents a critical component for modern high-performance data center networking. This passive breakout DAC is engineered specifically for NVIDIA Mellanox-based switching ecosystems, offering seamless compatibility with Mellanox's advanced fabric architecture. **Technical Specifications:** This cable features a robust 28AWG twinax copper conductor design encased in protective plastic jacketing, providing durability and consistent signal integrity across 3 meters. The QSFP-DD form factor on the transmit end breaks out to dual QSFP28 connectors, enabling flexible port density configurations and simplified network upgrades. Operating temperatures range from 0 to 70°C (32 to 158°F), making it suitable for varied data center environments. **Compliance & Certification:** Manufactured in compliance with RoHS and ELV directives, this cable adheres to EU directive 2002/95/EC and carries certifications from TUV and UL, ensuring safety and environmental responsibility. Custom brand programming is available for enterprise deployments requiring standardized branding across infrastructure components. **Key Benefits:** Passive technology eliminates power consumption and reduces operational heat output compared to active transceiver solutions. The direct attach design minimizes latency and maximizes throughput for latency-sensitive applications. At 3 meters, the cable balances reach capabilities with short-reach performance characteristics ideal for top-of-rack and spine-leaf topologies. **Applications & Use Cases:** Ideal for enterprise data centers, high-performance computing clusters, cloud infrastructure, and financial trading environments requiring ultra-low latency. Supports server-to-switch, switch-to-switch, and advanced networking configurations. The breakout design enables gradual network capacity expansion without complete infrastructure overhaul. **Shipping & Support:** Eligible for free standard shipping on orders over $99, available from multiple U.S. distribution points (Danville, CA and Beaufort, SC). Backed by a 90-day limited warranty for complete customer assurance.
