The JBX05955 Direct Attach Copper (DAC) breakout cable represents a cost-effective, high-performance solution for modern data center connectivity. As a NVIDIA Mellanox-compatible 200GBASE-CR4 cable, it bridges single 200GB ports to four 50GB SFP56 connections, making it ideal for network virtualization, high-frequency trading platforms, cloud infrastructure, and research computing facilities requiring ultra-low latency and maximum throughput. **Key Technical Specifications:** This 1-meter passive breakout cable features 30AWG twinax copper conductors with protective plastic jacketing, engineered to the IEEE 802.3cd standard. The QSFP56 male connector interfaces with standard 200GB ports, while four integrated SFP56 connectors provide granular bandwidth distribution. With zero active components, the passive design eliminates power consumption concerns and potential points of failure. **Compliance & Certification:** Fully RoHS and ELV compliant per EU Directive 2002/95/EC, with TUV and UL safety certifications. The cable meets QSFP56 MSA and CMIS specifications, ensuring compatibility across NVIDIA Mellanox equipment generations and select third-party platforms. **Performance & Reliability:** Operating reliably within 0-70°C temperature ranges, this cable maintains signal integrity across the entire 200GB bandwidth without attenuation concerns typical of longer DAC solutions. The compact 1-meter length minimizes clutter in dense server environments while supporting high-speed, low-latency applications requiring sub-microsecond response times. **Direct OEM Replacement:** Designed as a direct substitute for NVIDIA Mellanox OEM part numbers 980-9IA3X-00V001 and MCP7H70-V001R30, ensuring straightforward procurement and deployment within existing Mellanox-based infrastructure without compatibility concerns. **Support & Shipping:** Backed by a 90-day limited warranty with dedicated technical support. Ships from multiple US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Custom brand programming available for volume purchases and enterprise deployments.
