The JBX05443 2m Fortinet-Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents a cost-effective, high-performance networking solution for modern data center infrastructure. This specialized cable is engineered to deliver reliable 40 Gigabit Ethernet connectivity using proven passive direct attach copper (DAC) technology. **Technical Specifications & Design** This cable features genuine QSFP+ to QSFP+ connectors with 30AWG twinax copper conductors, delivering the signal integrity required for demanding enterprise applications. The 2-meter length provides flexibility in equipment rack configurations without introducing excessive signal degradation. Its compact 12x12x2 dimension profile ensures easy routing in congested server environments. **Fortinet Compatibility & Certification** Specifically engineered for Fortinet equipment, this DAC cable replaces original equipment manufacturer part numbers FN-CABLE-QSFP+2 and SP-CABLE-FS-QSFP+2. It fully complies with IEEE 802.3ba and SFF-8436 specifications, ensuring seamless integration with existing infrastructure. RoHS, TUV, and UL certifications confirm compliance with international safety and environmental standards. **Performance & Reliability** Passive DAC cables eliminate the power consumption and latency issues associated with active alternatives. Operating across a 0-70°C temperature range, this cable maintains performance in both standard and elevated-temperature data center environments. The robust plastic jacketing protects copper conductors while maintaining flexibility for installation in tight spaces. **Business Advantages** Unlike active optical cables, passive solutions offer significant cost savings without sacrificing performance. The 90-day limited warranty provides peace of mind, while availability from multiple U.S. fulfillment centers (Danville, CA and Beaufort, SC) ensures rapid deployment. Free standard shipping on orders over $99 adds further value for budget-conscious enterprises. **Applications** Ideal for server-to-switch connections, network upgrades, and high-speed data center interconnects. Perfect for organizations standardizing on Fortinet security appliances or expanding existing 40GB infrastructure. **Custom Branding Option** Custom brand programming is available for enterprise customers seeking vendor-specific labeling or bulk deployments.
