The JBX06533 represents a professional-grade solution for enterprise datacenter networking requirements. This 3-meter 400GBASE-CR8 QSFP-DD to 4x QSFP28 direct attach copper breakout cable bridges the gap between next-generation 400GB switching infrastructure and existing or legacy 100GB equipment, providing seamless network scalability and flexibility. Technical Specifications: The cable features 30AWG twinax copper construction that delivers superior electrical performance and signal integrity. Operating across temperatures from 0 to 70°C (32 to 158°F), it maintains reliability in diverse datacenter environments. With full compliance to IEEE 802.3bs, QSFP-DD MSA, and CMIS standards, this cable meets the most stringent industry requirements. Performance & Compatibility: As a direct replacement for the Arista H-D400-4Q100-3M, the JBX06533 ensures seamless integration into existing Arista-based network architectures. The passive breakout design eliminates the complexity and power consumption associated with active converters, reducing operational costs and simplifying deployment. Each QSFP28 port supports independent 100GBASE-CR4 signaling, enabling flexible port allocation and efficient bandwidth utilization. Quality Assurance: Manufactured with precision in Vietnam and China, this cable undergoes rigorous testing to ensure compliance with RoHS Directive 2002/95/EC and international safety standards including TUV and UL certification. The 90-day limited warranty provides confidence in your investment. Applications: Ideally suited for datacenter upgrades, high-performance computing clusters, storage area networks, and enterprise switching environments requiring reliable 400GB to 100GB breakout connectivity. The 3-meter length accommodates typical top-of-rack and end-of-row deployment scenarios. Customization: Custom brand programming is available, allowing OEM integration and private label applications. Value Proposition: By choosing the JBX06533, you invest in proven reliability, exceptional performance, and cost-effective network expansion without premium OEM pricing.
