The JBX04978 200GBASE-CR8 QSFP-DD to 2x QSFP28 breakout DAC cable represents the pinnacle of high-speed data center connectivity solutions. Specifically engineered for NVIDIA Mellanox infrastructure, this 1-meter passive copper cable enables seamless 200GB connections while maintaining the flexibility of dual 100GB QSFP28 interfaces. **Key Features & Specifications:** This passive breakout design leverages 30AWG twinax copper construction to deliver exceptional signal fidelity without active amplification. The QSFP-DD to dual QSFP28 configuration provides networking architects with intelligent breakout capabilities, allowing single 200GB ports to distribute traffic across dual 100GB connections. Operating across a wide temperature range (0-70°C / 32-158°F), it performs reliably in both standard and elevated thermal environments. **Performance & Compatibility:** Direct compatible with NVIDIA Mellanox MCP7H60-C001 specifications, this cable integrates seamlessly into existing infrastructure. The passive approach ensures zero latency overhead and minimal power draw—critical factors in power-constrained data centers. With 200GB data rates, it supports next-generation switch port density requirements. **Quality & Compliance:** Manufactured to strict international standards, the cable carries RoHS, TUV, and UL certifications, ensuring compliance with EU directive 2002/95/EC. Copper connectors provide superior conductivity while the plastic jacketing offers mechanical protection in active server environments. **Ideal Applications:** Perfect for hyperscale data centers, cloud infrastructure, high-performance computing clusters, and enterprise storage environments. This breakout cable excels in scenarios requiring flexible port configurations without sacrificing performance. **Purchase Benefits:** Backup inventory available from both Danville, CA and Beaufort, SC locations. Enjoy free standard shipping on orders exceeding $99. Custom brand programming is available for OEM integrations. The 90-day limited warranty provides peace of mind for mission-critical deployments. Direct replacement capability ensures minimal disruption during upgrades or maintenance.
