The JBX05868 1-meter 100GBASE-CR4 QSFP28 passive direct attach copper cable represents an excellent value solution for organizations deploying high-speed network infrastructure. This cable is engineered to meet the demanding requirements of modern data centers while providing superior performance reliability. **Technical Specifications:** This QSFP28 DAC cable utilizes premium 30AWG twinax copper conductors wrapped in protective plastic jacketing to ensure durability and consistent signal transmission. The dual QSFP28 connectors are precision-manufactured to guarantee optimal mating with Arista equipment and compatible networking platforms. Measuring precisely 1 meter in length, this cable is purpose-built for rack-level connectivity between switches and servers, minimizing latency while eliminating the need for external power supplies. **Performance & Compliance:** Qualified to IEEE 802.3bj and QSFP28 MSA standards, the JBX05868 delivers guaranteed 100GB data rates suitable for bandwidth-intensive applications. The cable meets all RoHS/ELV environmental directives (EU 2002/95/EC) and carries TUV and UL safety certifications, ensuring it meets stringent industrial standards. Operating reliably across temperatures from 0 to 70°C, this cable maintains performance consistency in diverse data center environments. **Applications & Compatibility:** Ideally suited for enterprise deployments, this Arista-compatible cable serves as a drop-in replacement for OEM part number CAB-Q-Q-100G-1M. Organizations can confidently integrate the JBX05868 into existing Arista switch infrastructure without compatibility concerns. The passive DAC design makes it particularly cost-effective for short-distance connections within racks and between adjacent equipment. **Value Proposition:** Compared to active optical cables or transceiver-based solutions, passive DAC cables offer significant cost savings without sacrificing performance over shorter distances. The JBX05868 eliminates recurring transceiver expenses while providing instant deployment and simplified inventory management. **Support & Warranty:** Backed by a comprehensive 90-day limited warranty and shipped from strategically located US warehouses in California and South Carolina, the JBX05868 ensures rapid delivery and responsive customer service. Free standard shipping applies to orders exceeding $99, making this solution accessible for both small and large-scale deployments.
