The JBX04960 200GBASE-CR8 QSFP-DD Direct Attach Copper Cable represents an essential infrastructure component for organizations modernizing their data center network architecture to support 200GB Ethernet speeds. Technical Specifications: This 2-meter passive breakout DAC cable features a single QSFP-DD (Quad Small Form Factor Pluggable Double Density) male connector transitioning to two QSFP28 (Quad Small Form Factor Pluggable 28) female connectors, enabling seamless integration with existing QSFP28-equipped network infrastructure while supporting full 200GBASE-CR8 throughput. The 28AWG twinax copper construction provides superior signal integrity and minimizes insertion loss across the cable's length. Key Advantages: As a passive solution, this cable eliminates the operational overhead and thermal considerations associated with active electrical components, delivering cost-effective connectivity without requiring additional power provisioning. The compact form factor optimizes rack space utilization while maintaining professional-grade durability through plastic jacketing and comprehensive safety certifications. Compatibility & Applications: This cable directly replaces Arista's CAB-D-2Q-200G-2M part number and is compatible with Arista's 200GB switching infrastructure. Ideal applications include data center interconnects, spine-leaf fabric architecture, high-frequency trading environments, and HPC clusters where latency-sensitive, high-bandwidth requirements demand reliable copper connectivity. Certifications & Compliance: Fully compliant with RoHS/ELV directives (EU 2002/95/EC), TUV certified, and UL listed for safety assurance. Manufactured in Vietnam and China under strict quality standards. Shipping & Support: Enjoy free standard shipping on orders exceeding $99 from our facilities in Danville, CA or Beaufort, SC. All units include a 90-day limited warranty. Custom brand programming is available for volume deployments. Invest in proven 200GB connectivity infrastructure with the reliability and performance your critical network demands.
