The JBX05998 1-meter QSFP56 Direct Attach Copper (DAC) cable represents an essential infrastructure component for modern high-speed data center deployments. Engineered specifically for 200GBASE-CR4 applications, this passive copper solution delivers exceptional value for organizations requiring reliable, cost-effective connectivity without the expense of optical transceivers. **Technical Specifications & Performance** This cable achieves 200Gbps data transmission rates using proven passive copper technology. The 30AWG twinax construction ensures optimal impedance matching and signal integrity across the full 1-meter length. Qualified to IEEE 802.3cd and QSFP56 MSA/CMIS standards, it integrates seamlessly with enterprise-class networking equipment. The cable operates reliably across the industrial temperature range of 0°C to 70°C (32°F to 158°F), accommodating both climate-controlled data centers and field deployment scenarios. **Compatibility & Integration** Designed as a direct replacement for Arista part number C-Q200-Q200-1M, this cable is compatible with Arista switches and other QSFP56-equipped networking devices. QSFP56 dual connectors on both ends enable straightforward installation without adapters or additional components. **Quality & Compliance** Manufactured to strict international standards, the cable carries full RoHS/ELV compliance per EU directive 2002/95/EC, TUV certification, and UL safety approval. The 90-day limited warranty provides peace of mind for your infrastructure investment. Custom brand programming is available for integration with OEM requirements. **Practical Applications** Ideal for leaf-spine architectures, switch-to-switch interconnects, server-to-storage links, and other short-reach, high-bandwidth requirements. The passive design eliminates power consumption and heat generation associated with active solutions, reducing operational costs and environmental impact. **Logistics & Support** Ships quickly from US locations (Danville, CA or Beaufort, SC) with free standard shipping on orders exceeding $99. Professional support available for custom configurations and large-scale deployments.
