The JBX05949 200GBASE-CR4 QSFP56 Breakout DAC Cable represents cutting-edge passive copper technology for modern data center networking. This 1.5-meter direct attach copper cable provides a cost-effective solution for organizations seeking to expand their 200GB network capacity without investing in active optical infrastructure. **Technical Specifications & Compliance** This passive breakout cable features a QSFP56 connector transitioning to four individual SFP56 ports, enabling efficient port multiplication for high-density server deployments. Manufactured with 30AWG twinax copper construction, the cable delivers exceptional signal fidelity across the full 1.5-meter span. The design is fully compliant with IEEE 802.3cd specifications and QSFP56 MSA standards, guaranteeing compatibility with enterprise-grade networking equipment. **HPE Compatibility & OEM Replacement** As a direct substitute for HPE part number R6F27A-1.5M, this cable integrates seamlessly into existing HPE infrastructure without requiring firmware updates or configuration changes. The cable is optimized for HPE switches, servers, and storage systems utilizing QSFP56 connectivity. **Reliability & Certification** All components undergo rigorous testing to meet RoHS, TUV, and UL safety certifications, ensuring environmental compliance and operational safety. The cable operates reliably across 0-70°C temperature ranges, suitable for both standard and warm-aisle data center environments. A 90-day limited warranty provides additional peace of mind for mission-critical deployments. **Use Cases & Applications** Ideal for server virtualization, cloud infrastructure, high-frequency trading environments, and enterprise backup solutions. The passive design eliminates power consumption concerns while delivering deterministic latency for latency-sensitive applications. Perfect for organizations transitioning from 100GB to 200GB infrastructure without replacing entire switch architectures. **Advantages Over Alternatives** Unlike active breakout cables, this passive solution requires no external power, reducing operational complexity and heat generation. The compact 1.5-meter length optimizes rack space while maintaining full bandwidth capacity. Ships from U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, supporting rapid deployment timelines.
