The JBX05373 1m Arista Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents an ideal solution for organizations seeking cost-effective, high-performance network interconnectivity. This purpose-built cable integrates copper twinax technology with QSFP+ connectors to facilitate seamless 40 gigabit per second (40GB) data transmission across compatible network infrastructure. Key Technical Specifications: This cable features 30AWG gauge copper construction with dual QSFP+ connectors, measuring just 1 meter in length—perfect for short-reach, high-density connections in modern data centers. The passive DAC (Direct Attach Copper) architecture eliminates the electronic components found in active cables, resulting in lower power consumption, reduced heat generation, and minimal electromagnetic interference. Compliance and Certification: Fully qualified to IEEE 802.3ba standards and supporting the SFF-8436 specification, this cable delivers certified performance. RoHS and ELV directives compliance ensure environmental responsibility, while UL and TUV certifications validate safety and quality standards. Application and Compatibility: Designed for Arista Networks infrastructure, this cable replaces OEM part number CAB-Q-Q-1M and integrates seamlessly into existing enterprise networks, cloud environments, and high-performance computing clusters. The copper construction provides excellent signal integrity for latency-sensitive applications. Operational Benefits: With an operating temperature range of 0-70°C (32-158°F), this cable performs reliably across diverse deployment scenarios. The 90-day limited warranty provides peace of mind, while custom brand programming is available for OEM requirements. Ships from strategically located US warehouses (Danville, CA and Beaufort, SC) with expedited delivery options available. Why Choose This Solution: Passive DAC cables eliminate the cost and complexity of active solutions while delivering identical performance for short-reach connections. The JBX05373 offers an economical pathway to 40GB connectivity without sacrificing reliability or speed, making it an excellent choice for cost-conscious organizations requiring premium network performance.
