The JBX05458 2m NVIDIA Mellanox Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents cutting-edge networking infrastructure technology designed for modern data centers and high-performance computing environments. **Technical Excellence** Built to IEEE 802.3ba specifications, this cable delivers reliable 40Gbps performance with QSFP+ connectors on both ends. The 30AWG twinax copper composition provides superior electrical characteristics, enabling consistent data transmission without signal degradation. At just 2 meters, it's perfectly suited for top-of-rack (ToR) and end-of-row (EoR) switching architectures. **Compatibility & Integration** Fully compatible with NVIDIA Mellanox networking equipment, this DAC cable seamlessly integrates into existing infrastructure. It replaces OEM part numbers MCP1700-B002E, MC2206130-002, and MC2210130-002, making it an excellent upgrade option for legacy systems. The passive design eliminates power consumption, reducing operating costs and heat generation. **Quality & Reliability** Manufactured to the highest standards with RoHS and ELV compliance, this cable meets stringent EU Directive 2002/95/EC requirements. Comprehensive safety certifications (RoHS, TUV, UL) ensure safe operation in professional environments. The 90-day limited warranty provides confidence in your investment. **Performance Characteristics** Operating across the full temperature range (0-70°C), this cable performs reliably in any data center environment. The plastic jacketing protects against physical damage while maintaining flexibility for installation in tight spaces. Dimensions of 12x12x2 ensure proper fit in standard cable management systems. **Enterprise Features** Custom brand programming is available for enterprise deployments, allowing organizations to standardize on branded infrastructure. Free standard shipping on orders over $99 makes bulk purchasing convenient, with strategic shipping locations in California and South Carolina ensuring rapid delivery. **Ideal Applications** Perfect for data center switch fabric connectivity, storage area networks (SANs), high-performance computing clusters, and enterprise networking environments where reliability and performance are paramount.
