The JBX05459 2-meter 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents the optimal connectivity solution for high-performance data center environments running Palo Alto Networks infrastructure. This professional-grade networking cable combines cost-effectiveness with enterprise-level reliability. Technical Specifications: This cable meets IEEE 802.3ba and SFF-8436 standards, ensuring compatibility with next-generation switching equipment. The 30AWG twinax copper construction provides excellent impedance control and signal fidelity across the full 40GB bandwidth. Copper connectors on both QSFP+ ends deliver secure, repeatable connections with minimal insertion loss. Performance & Compatibility: As a passive direct attach cable, the JBX05459 eliminates the complexity and cost associated with active optical alternatives. It directly replaces Palo Alto Networks OEM part number PAN-QSFP-CU-2M and integrates seamlessly into existing network architectures. The 2-meter length provides ideal spacing for modern data center rack configurations while maintaining signal integrity. Compliance & Safety: Fully RoHS and ELV compliant, this cable meets EU directive 2002/95/EC and carries TUV and UL certifications. It operates reliably across the industrial temperature range (0-70°C), suitable for both controlled data center environments and edge deployments. Use Cases: • Enterprise data center interconnection • High-speed server cluster networking • Storage area network (SAN) applications • Palo Alto Networks firewall deployments • Mission-critical network upgrades Value Proposition: Eliminate vendor lock-in while reducing total cost of ownership. This certified compatible cable delivers OEM-level performance at competitive pricing. Backed by a 90-day limited warranty, free domestic shipping from strategically located US warehouses, and responsive customer support. Maintenance & Longevity: The robust plastic jacketing protects against environmental contaminants while the precision twinax shielding maintains signal integrity. Ensure optimal performance by avoiding sharp bends (minimum 1-inch bend radius) and maintaining connections free from dust and debris.
