The JBX05201 NVIDIA Mellanox compatible 40GBASE-CR4 QSFP+ breakout cable represents a cost-effective, high-performance solution for modern data center networking infrastructure. This 1-meter passive direct attach copper (DAC) cable connects QSFP+ interfaces to four SFP+ ports, enabling flexible network configurations without active electronic components. Designed to OEM specification MC2609130-001, this breakout cable delivers consistent 40GB data rates while maintaining exceptional signal integrity. The 30AWG twinax copper construction provides optimal electrical characteristics, while the protective plastic jacketing ensures durability in demanding server room environments. Qualified to IEEE 802.3ba specifications, the cable guarantees compatibility with NVIDIA Mellanox switching and networking infrastructure. Key technical features include RoHS and ELV compliance, meeting EU Directive 2002/95/EC environmental standards. Safety certifications from TUV and UL validate its reliability for enterprise deployments. The cable operates reliably across 0-70°C temperature ranges, supporting both standard and high-ambient server rooms. Ideal applications include: data center interconnects, server-to-switch connections, storage area networking (SAN), and high-performance computing (HPC) cluster deployments. The 1-meter length suits typical rack configurations and eliminates cable management complexity. This passive breakout DAC cable offers significant advantages over active solutions: lower power consumption, zero latency addition, and reduced total cost of ownership. Ships from two U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Custom brand programming is available for enterprise deployments. Backed by a 90-day limited warranty and manufactured in Vietnam and China, the JBX05201 provides the reliability and performance required for mission-critical networking environments. Compatible with NVIDIA Mellanox platforms and other industry-standard 40GBASE-CR4 implementations.
