The JBX05147 3m 400GBASE-CR8 QSFP-DD Direct Attach Copper Cable represents a cost-effective, high-performance solution for modern data center infrastructure requiring ultra-high-speed connectivity. As a passive DAC cable, it eliminates the complexity and power overhead associated with active optical solutions while delivering full 400GB throughput performance. Technical Excellence: This direct attach copper cable features precision-engineered 30AWG twinax construction encased in durable plastic jacketing. The QSFP-DD connectors provide the latest in modular connectivity standards, supporting simultaneous dual 200G channels or single 400G operation. The 3-meter length strikes an optimal balance between flexibility and signal integrity, making it ideal for intra-rack and rack-to-rack connections in high-density data centers. Dell Ecosystem Integration: Tested and validated for seamless compatibility with Dell infrastructure, the cable replaces multiple Dell OEM part numbers (470-ACYV, 470-ADYV-3M, 470-ADYT-3M, 470-ADFD, and 470-ACYY), ensuring drop-in compatibility with existing Dell systems. This eliminates procurement complexity and guarantees reliable operation. Compliance & Reliability: Manufactured to the strictest standards with RoHS and ELV compliance, this cable meets EU Directive 2002/95/EC requirements. It's qualified to ETC 400GBASE-CR8 specifications and CMIS standards, with operating temperature range of 0-70°C suitable for various environmental conditions. Safety certifications include RoHS, TUV, and UL validation. Cost-Effective Performance: As a passive solution, this DAC cable reduces total cost of ownership by eliminating power supply requirements and associated cooling needs. Ships from multiple US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, plus a 90-day limited warranty providing peace of mind. Ideal Applications: Perfect for hyperscale data centers, enterprise networks, storage solutions, and high-performance computing environments requiring reliable 400G connectivity without optical infrastructure complexity. The passive design makes it an environmentally conscious choice for sustainability-focused operations.
