The JBX05077 3-meter 400GBASE-CR8 QSFP-DD to 8x SFP56 passive breakout DAC cable represents an essential component for modern high-speed data center architecture. Engineered as a direct replacement for Juniper's QDD-8x50G-3M part number, this cable delivers exceptional performance at a fraction of the cost of active alternatives while maintaining industry-leading reliability. Key Technical Specifications: This 28AWG twinax copper cable is constructed to transmit low-voltage network signals with exceptional clarity and minimal signal degradation. The QSFP-DD (Quad Small Form Factor Double Density) connector interfaces with eight individual SFP56 (Small Form Factor Pluggable 56Gbps) ports, enabling flexible network configurations. Operating across 0-70°C, the cable maintains performance consistency in diverse data center environments. Compliance & Standards: Fully certified to ETC 400GBASE-CR8 specifications and QSFP-DD MSA standards, the JBX05077 meets RoHS, TUV, and UL safety certifications. EU directive 2002/95/EC compliance ensures compatibility with global installations. Applications & Benefits: Ideal for data centers, cloud computing facilities, and enterprise networks requiring 400GB connectivity. The 3-meter length optimizes inter-rack and intra-rack deployments without excess cable management overhead. As a passive solution, it eliminates power consumption concerns while reducing operational costs compared to active cables. Juniper Compatibility: Direct compatibility with Juniper networking equipment ensures plug-and-play installation without configuration complexity. Perfect for organizations standardizing on Juniper infrastructure. Warranty & Support: Backed by a 90-day limited warranty and available for custom brand programming, ensuring integration flexibility.
