The JBX05053 represents a cost-effective solution for organizations upgrading to 400GB network infrastructure. As a passive direct attach copper (DAC) cable, it eliminates the need for active transceivers, reducing power consumption and operational expenses while maintaining exceptional performance and reliability. **Technical Specifications:** This 1-meter cable features QSFP-DD to 4x QSFP56 connectivity, supporting full 400GBASE-CR8 data rates. The 30AWG twinax copper conductors deliver optimal impedance matching and minimal signal loss. Operating temperature range of 0-70°C ensures compatibility with standard and demanding data center environments. **Compatibility & Performance:** Directly compatible with Dell systems, this cable replaces Dell part numbers 470-AFPF-1M and 470-AFPH-1M. It fully qualifies under ETC 400GBASE-CR8 specifications and adheres to QSFP-DD MSA (Multi-Source Agreement) and CMIS (Common Management Interface Specification) standards. The breakout configuration allows single 400GB port expansion to four independent 100GB connections. **Quality & Compliance:** Manufactured with rigorous quality control in Vietnam and China facilities, this cable meets RoHS Directive 2002/95/EC and ELV (Electrical and Electronic Equipment) requirements. TUV and UL safety certifications provide additional assurance of reliability and performance consistency. **Practical Applications:** Ideal for hyperscale data centers, financial institutions requiring low-latency connectivity, cloud service providers, and enterprises deploying next-generation network architectures. The passive design eliminates heat generation and complexity, making it perfect for dense switch configurations. **Warranty & Support:** Backed by a 90-day limited warranty covering defects in materials and workmanship. Custom brand programming available for enterprise deployments. Ships with free standard shipping on qualifying orders from strategically located U.S. fulfillment centers.
