The JBX05967 200GBASE-CR4 QSFP56 Direct Attach Copper Cable represents a cost-effective, high-performance solution for modern data center infrastructure. As a passive DAC technology, it eliminates power consumption and heat generation associated with active optical solutions, making it an ideal choice for bandwidth-intensive, latency-sensitive applications. **Technical Specifications:** This 2-meter cable features precision-engineered 26AWG twinax copper construction with professional-grade QSFP56 connectors on both ends. The passive design supports full 200GB Ethernet speeds while maintaining signal integrity over the cable length. Dimensions of 12x12x2mm ensure compatibility with standard rack-mount equipment with minimal spatial requirements. **Compliance & Certifications:** Fully qualified to IEEE 802.3cd specifications and QSFP56 Multi-Source Agreement (MSA) standards, the cable meets EU RoHS directive 2002/95/EC requirements. Safety certifications include RoHS, TUV, and UL standards, ensuring compliance with international networking infrastructure regulations. **Compatibility & Application:** Direct replacement for HPE R5Z78A (P/N P06149-B24), this cable integrates seamlessly with HPE data center equipment and compatible QSFP56-equipped network infrastructure. Ideal applications include: - High-performance computing clusters - Data center fabric connectivity - Enterprise storage area networks (SANs) - Content delivery network (CDN) infrastructure - Financial trading environments requiring ultra-low latency **Performance & Reliability:** With operating temperatures from 0-70°C (32-158°F), the cable performs reliably in standard and climate-controlled data center environments. The passive design ensures zero power draw and minimal electromagnetic interference. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty, each cable ships from strategically located US distribution centers (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Custom brand programming is available for volume OEM deployments.
