The JBX05207 2m 40GBASE-CR4 QSFP+ to SFP+ Direct Attach Copper (DAC) breakout cable represents a premium solution for enterprise data center networking. Designed as a Dell 470-ABXO compatible alternative, this passive breakout cable delivers exceptional performance in demanding network environments where reliability and efficiency are paramount. **Technical Excellence** This cable features 30AWG twinax copper construction optimized for 40GB transmission speeds. As a passive DAC solution, it requires no external power, reducing operational costs and simplifying infrastructure management. The cable meets IEEE 802.3ba specifications and maintains signal integrity across its full 2-meter length, eliminating latency concerns associated with active solutions. **Connectivity Architecture** The QSFP+ to 4x SFP+ breakout configuration enables versatile network topologies. This allows organizations to transition from legacy SFP+ infrastructure to modern QSFP+ equipment without requiring complete overhauls. The design supports simultaneous multi-channel communication, distributing 40GB bandwidth across four independent 10GB SFP+ connections. **Compliance & Reliability** Full RoHS (Restriction of Hazardous Substances) and ELV compliance ensures environmental responsibility. TUV and UL safety certifications provide confidence in operational integrity. The cable operates reliably within 0-70°C temperature parameters, accommodating diverse data center environments from cooled server rooms to warm equipment closets. **Practical Advantages** The 2-meter length strikes an optimal balance between reach and cable management. Direct OEM compatibility with Dell systems 470-ABXO and 470-ABXQ eliminates firmware concerns and integration challenges. Copper construction provides superior EMI shielding compared to optical alternatives, crucial in electrically dense rack environments. **Application Scenarios** Perfect for blade server interconnects, storage area network (SAN) implementations, high-frequency trading environments, and cloud infrastructure buildouts. Organizations can achieve 40GBASE-CR4 connectivity while maintaining flexibility with existing SFP+ network cards and switching infrastructure. **Support & Warranty** 90-day limited warranty provides peace of mind. Ships from US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, ensuring cost-effective procurement for volume deployments. Custom brand programming available for OEM customers requiring white-label solutions.
