The JBX05016 800GBASE-CR8 QSFP-DD to 4x QSFP112 direct attach copper (DAC) breakout cable represents a premium solution for organizations deploying next-generation 800GB networking infrastructure. This 2-meter cable is engineered to be a drop-in replacement for Arista's C-D800-4Q200-2M, delivering identical performance characteristics with proven reliability. Technical Excellence: Constructed with 28AWG twinax copper conductors, this passive breakout cable provides superior signal integrity over the 2-meter span. The robust plastic jacketing protects against physical damage and environmental stress, while the passive architecture ensures zero-latency signal transmission—critical for latency-sensitive applications in financial trading, real-time analytics, and cloud infrastructure. Compliance & Certification: Full compliance with RoHS Directive 2002/95/EC, combined with TUV and UL safety certifications, ensures this cable meets stringent international standards. These certifications are essential for regulated industries and enterprise deployments requiring documented compliance. Applications & Use Cases: Ideal for data center environments, the QSFP-DD to QSFP112 breakout configuration enables flexible port distribution from high-density 800GB switches. Common deployments include server interconnects, storage area networks (SANs), and high-performance computing (HPC) clusters where bandwidth and reliability are paramount. Operational Specifications: Operates reliably across 0-70°C temperature range, suitable for standard and warm-running data center environments. The 2-meter length accommodates typical rack-to-rack distances without excessive slack or tension. Manufactured in Vietnam and China with quality assurance protocols, supporting immediate availability from US-based distribution centers. Value Proposition: This passive DAC cable eliminates the cost and complexity of active electronics while delivering enterprise-grade performance. The 90-day limited warranty provides peace of mind, backed by responsive customer support. Free standard shipping on orders exceeding $99 reduces procurement costs for volume deployments. Maintenance & Care: Passive cables require no special maintenance. Ensure connectors remain clean and dust-free, store at room temperature, and avoid excessive cable bending at connector interfaces to maintain optimal performance throughout the cable's operational life.
