The JBX06535 represents a sophisticated solution for modern data center networking infrastructure, specifically engineered to bridge the gap between emerging 400G technologies and existing QSFP28 ecosystems. As a direct replacement for the Arista H-D400-4Q100-5M cable, this 5-meter active breakout DAC delivers enterprise-grade performance for organizations deploying next-generation network architectures. Technical Excellence This 400GBASE-CR8 compatible cable features active electronic components that enhance signal conditioning and reliability over extended distances. The 28AWG twinax copper construction provides optimal impedance matching and minimal signal degradation, critical for maintaining data integrity in high-bandwidth applications. The cable's construction utilizes premium materials with plastic jacketing that protects against environmental factors while remaining flexible for installation in dense rack environments. Qualifications and Compliance Fully compliant with ETC 400GBASE-CR8 MSA specifications and CMIS standards, the JBX06535 undergoes rigorous testing to ensure compatibility and performance. RoHS, TUV, and UL certifications confirm adherence to international safety and environmental standards, making it suitable for regulated industries and enterprise deployments. Application Scenarios This breakout cable excels in data center switching architectures where 400G uplinks connect to arrays of 100G or 25G services. It's ideal for: hyperscale cloud infrastructure, high-performance computing clusters, financial trading systems, and enterprise campus backbones requiring carrier-class reliability. Operational Reliability Designed for continuous operation between 0-70°C (32-158°F), the cable maintains performance in standard to moderately heated environments. The 90-day limited warranty provides peace of mind, backed by customer service support. Manufactured in Vietnam and China with strict quality controls, each unit is validated before shipment. Value Proposition Compared to standard passive DAC solutions, this active breakout cable offers superior reach and signal integrity. Versus optical alternatives, it eliminates transceiver costs and complexity while providing cost-effective 400G-to-QSFP28 bridging. With free standard shipping on orders exceeding $99, procurement becomes economical for volume deployments.
