The JBX05700 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents the pinnacle of high-speed data center networking solutions. Specifically engineered for Extreme Networks compatibility, this 5-meter interconnect cable delivers consistent 100GB Ethernet performance, making it an indispensable component for enterprise infrastructure deployments. **Technical Excellence:** This passive direct attach copper (DAC) cable adheres to strict IEEE 802.3bj specifications and QSFP28 Multi-Source Agreement standards. The 26AWG twinax construction ensures optimal signal integrity, while the robust plastic jacketing provides durability in high-density cabling environments. Operating across temperatures from 0 to 70°C (32 to 158°F), it maintains peak performance in diverse data center conditions. **Key Advantages:** Passive DAC technology offers significant benefits over active alternatives: zero power consumption, reduced heat generation, and lower total cost of ownership. The cable eliminates compatibility issues with universal implementation across standard QSFP28 ports, providing seamless integration with existing Extreme Networks equipment. **Compliance & Certification:** Fully RoHS and EU directive 2002/95/EC compliant, with TUV and UL safety certifications. These credentials ensure the cable meets stringent environmental and safety standards required by enterprise procurement departments and regulatory frameworks. **Applications:** Ideal for server-to-switch connections, switch-to-switch inter-connections, and storage area network (SAN) deployments. The 5-meter length perfectly addresses typical rack-to-rack distances in data center environments without excessive cabling bulk. **OEM Compatibility:** Direct replacement for Extreme Networks part numbers including 100G-DACP-QSFP5M, 10414, 100G-QSFP-QSFP-P-0501, and AA1405032-E6, ensuring hassle-free upgrades and migrations. **Quality Assurance:** Backed by a 90-day limited warranty and available with custom brand programming options. Ships from strategically located U.S. warehouses in Danville, CA and Beaufort, SC, with free standard shipping on qualifying orders, ensuring rapid deployment and cost efficiency.
