The JBX05999 1-meter QSFP56 Direct Attach Copper Cable represents a cost-effective solution for 200Gbps network deployments in modern data centers and enterprise environments. As a passive DAC (Direct Attach Copper) cable, it eliminates the need for power consumption while maintaining the high-speed performance required for contemporary networking applications. **Key Technical Features:** This QSFP56-to-QSFP56 copper twinax cable is constructed with premium 30AWG conductors, providing optimal signal integrity over its 1-meter span. The cable fully complies with IEEE 802.3cd specifications and adheres to the QSFP56 Multi-Source Agreement (MSA) and CMIS standards, ensuring compatibility with leading network equipment manufacturers. Its passive design makes it ideal for short-reach connections typical in rack-to-rack and intra-datacenter scenarios. **Compliance and Certifications:** Manufactured to meet stringent quality standards, this cable carries RoHS and ELV compliance certifications, along with TUV and UL safety approvals. These certifications guarantee environmental responsibility and operational safety in regulated environments. **Performance Specifications:** Operating reliably between 0-70°C (32-158°F), the cable delivers consistent 200GBASE-CR4 performance. The robust plastic jacket protects copper conductors from physical damage while maintaining flexibility for installation in constrained spaces. **Cisco Compatibility:** Designed as a direct replacement for Cisco part number QSFP-200-CU1M, this cable integrates seamlessly into existing Cisco infrastructure without requiring firmware updates or configuration changes. **Value Proposition:** Unlike active optical cables or active copper solutions, passive DAC cables reduce total cost of ownership by eliminating power requirements and associated cooling infrastructure. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 adds additional value. This cable represents the intelligent choice for organizations seeking reliable, budget-conscious 200Gbps connectivity without compromising on quality or performance standards.
