The JBX05938 2m Arista C-Q200-4S50-2M Compatible 200GBASE-CR4 QSFP56 breakout DAC cable represents a premium passive connectivity solution for modern data center architectures. As a direct attach copper (DAC) breakout cable, it converts a single QSFP56 port into four SFP56 connections, enabling unprecedented flexibility in network port density and traffic management. Key Technical Specifications: This high-performance cable features 26AWG twinax copper conductors optimized for signal integrity at 200GB speeds. The 2-meter length accommodates typical rack-to-rack and blade-to-switch connectivity scenarios without signal degradation. Operating temperatures from 0°C to 70°C ensure reliable performance across standard data center environments. Compliance & Certification: The cable meets stringent industry standards including IEEE 802.3cd, QSFP56 MSA, and CMIS specifications. Safety certifications from RoHS, TUV, and UL guarantee environmental compliance and workplace safety. EU directive 2002/95/EC (RoHS) compliance ensures the cable meets global regulatory requirements for hazardous substances elimination. Advantages of Passive Breakout DACs: Unlike active solutions, passive DAC cables require no external power, reducing operational costs and eliminating potential points of failure. The direct copper connection minimizes latency, making this solution ideal for latency-sensitive applications including high-frequency trading, cloud infrastructure, and real-time data processing. Application Scenarios: Perfect for Arista DCS environments, this cable excels in data center, enterprise networking, and cloud computing deployments. The breakout configuration supports flexible lane assignments, enabling IT teams to optimize bandwidth allocation and network topology without hardware upgrades. Customization & Support: Custom brand programming is available for enterprise customers seeking standardized network assets. With free standard shipping on orders exceeding $99 and shipments from strategically located U.S. facilities (Danville, CA and Beaufort, SC), rapid deployment is assured. The 90-day limited warranty provides peace of mind for critical infrastructure investments. This OEM-equivalent replacement cable delivers enterprise-grade reliability at competitive pricing, making it an essential component for organizations expanding or upgrading 200GB network capacity.
