The JBX05943 3-meter 200GBASE-CR4 QSFP56 to SFP56 breakout DAC cable represents a high-performance, cost-effective solution for modern data center networks requiring ultra-high-speed connectivity. As a direct compatible replacement for the Arista C-Q200-4S50-3M, this passive direct-attach copper cable eliminates the complexity and latency associated with active optical transceivers, making it ideal for environments where simplicity and reliability are paramount. Key Features & Specifications: This breakout cable delivers 200Gb/s data rates through a single QSFP56 connector splitting into four SFP56 channels, enabling flexible network segmentation and load distribution. The 26AWG twinax copper construction ensures superior signal integrity while maintaining the 3-meter length requirement for typical rack-to-rack installations. The durable plastic jacketing protects against environmental contaminants common in data center facilities. Compliance & Certifications: Qualified to IEEE 802.3cd specifications and QSFP56 MSA standards, this cable meets the most stringent industry requirements. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility and regulatory adherence. Safety certifications from TUV and UL verify manufacturing quality and performance reliability. Optimal Use Cases: Designed for Arista-based network deployments, this breakout cable excels in high-density switch interconnections, load balancer configurations, and direct server connectivity scenarios. The passive design eliminates power requirements and reduces operational overhead compared to active alternatives. Operational Excellence: Functions reliably across the 0-70°C operating temperature range, accommodating both standard and demanding data center environments. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 delivers exceptional value. Custom brand programming is available for OEM partnerships and volume deployments.
