The JBX05350 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents an essential infrastructure component for modern high-speed networking environments. Engineered specifically for Brocade-compatible equipment, this 1.5-meter cable delivers enterprise-grade performance and reliability. **Technical Excellence** Built with premium 30AWG twinax copper construction, this passive DAC cable meets rigorous IEEE 802.3ba and SFF-8436 specifications. The cable's passive design—meaning no active electronic amplification—ensures zero power consumption while maintaining exceptional signal integrity over the 1.5-meter distance. This makes it ideal for rack-to-rack connectivity and server-to-switch applications where distance permits passive technology. **Compliance & Certification** Fully RoHS, TUV, and UL certified, this cable meets EU Directive 2002/95/EC requirements. It replaces Brocade OEM part number 40G-QSFP-C-0151, providing a cost-effective alternative without compromising quality or performance. The cable operates reliably across industrial temperature ranges from 0°C to 70°C (32°F to 158°F). **Key Advantages** • **Cost-Effective**: Passive technology eliminates active component expenses • **Power Efficient**: Zero power consumption reduces operational costs • **Reliable Connectivity**: Direct copper-to-copper connection ensures low latency • **Easy Installation**: QSFP+ connectors provide simple, tool-free deployment • **Vendor Compatibility**: Works seamlessly with Brocade networking equipment **Applications** Perfect for data center environments, server farms, and enterprise networks requiring high-speed, low-latency interconnects. Ideal for switch-to-server, server-to-server, and switch-to-switch connections within cabinet and adjacent rack configurations. **Warranty & Support** Backed by a 90-day limited warranty and available with custom brand programming options. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99.
