The JBX05002 400GBASE-CR8 QSFP-DD to QSFP56 Direct Attach Copper cable represents the pinnacle of high-speed datacenter connectivity solutions. At 1.5 meters, this passive breakout DAC cable bridges the gap between legacy QSFP56 infrastructure and next-generation 400GB network environments, making it an essential component for modern data centers undergoing network upgrades. **Technical Specifications:** This cable features 30AWG twinax copper conductors with durable plastic jacketing, designed to withstand the rigorous demands of active datacenter environments. The QSFP-DD male connector terminates to two QSFP56 female connectors, enabling straightforward port mapping and flexible network architecture. Operating across a temperature range of 0-70°C, it maintains signal integrity in both controlled and variable datacenter conditions. **Compatibility & Integration:** As a direct replacement for Dell part number 470-BCCG, the JBX05002 integrates seamlessly into Dell PowerSwitch environments and other enterprise switches supporting 400GBASE-CR8 standards. The cable is qualified to ETC 400GBASE-CR8 specifications and conforms to QSFP-DD MSA and CMIS standards, ensuring reliable operation with certified equipment. **Key Advantages:** Passive DAC technology eliminates power consumption and associated heat generation, reducing overall datacenter thermal load. The 1.5-meter length optimizes for short-reach interconnects within racks and adjacent enclosures. RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility and future-proofing against regulatory changes. **Use Cases:** Ideal for hyperscale data centers, cloud infrastructure providers, financial institutions, and enterprise IT departments requiring high-bandwidth, low-latency connections. Perfect for server-to-switch, switch-to-switch, and high-speed storage networking applications. **Quality Assurance:** Manufactured in Vietnam and China using stringent quality standards, backed by a 90-day limited warranty. Custom brand programming available for OEM and enterprise customers. Free standard shipping on orders exceeding $99.
