The JBX06451 25GBASE-CR SFP28 Passive DAC Cable represents the ideal solution for demanding data center environments requiring cost-effective, high-speed connectivity. This 1-meter passive direct attach copper cable is specifically engineered to meet the rigorous demands of modern network infrastructure while maintaining exceptional value. **Technical Excellence** Built to IEEE 802.3by specifications, this cable delivers consistent 25GB/s performance with minimal latency. The 30AWG twinax copper construction ensures optimal signal integrity, while the durable plastic jacketing protects against environmental stress. Operating across a wide temperature range of 0°C to 70°C (32°F to 158°F), this cable performs reliably in diverse data center conditions. **Complete Compatibility** Designed as a drop-in replacement for NVIDIA Mellanox infrastructure, the JBX06451 is directly compatible with Mellanox switches, network adapters, and storage solutions. It replaces multiple OEM part numbers (MCP2M00-A001, 980-9I63J-00A001, MCP2M00-A001E30N, 980-9I63L-00A001), simplifying procurement and inventory management. **Passive Technology Advantage** Unlike active cables, this passive design eliminates power consumption requirements while delivering enterprise-grade performance. This translates to reduced operational costs and lower heat generation in densely populated switch environments. **Certified Quality** Comprehensive compliance certifications including RoHS, TUV, and UL ensure this cable meets international safety and environmental standards. Manufactured in Vietnam and China to strict quality specifications, each cable undergoes rigorous testing before shipment. **Practical Applications** Ideal for hyperscale data centers, cloud infrastructure providers, high-performance computing clusters, and enterprise network upgrades. The 1-meter length optimally accommodates standard rack configurations and inter-switch connections without excess cable management overhead. **Customer Support** Every purchase includes a 90-day limited warranty providing peace of mind. Free standard shipping on orders exceeding $99, with convenient fulfillment from Danville, CA and Beaufort, SC locations ensures rapid delivery. Custom brand programming is available for volume orders.
