The JBX06379 25GBASE-CR SFP28 Passive Direct Attach Copper Cable represents a cost-effective and reliable solution for modern data center infrastructure. This 5-meter cable harnesses the advantages of passive DAC technology to deliver consistent 25GB performance without the complexity and expense of active components. Construction and Design: Manufactured from high-quality copper with precision 26AWG twinax wiring, this cable ensures minimal signal degradation and superior electromagnetic shielding. The durable plastic jacketing provides both protection and flexibility for easy installation in tight equipment racks and cable management scenarios. Weighing just 12x12x5 dimensions, it's designed for easy routing and doesn't consume valuable rack space. Performance and Compatibility: Qualified to IEEE 802.3by specifications with SFF-8402 and SFF-8472 compliance, this cable integrates seamlessly with Dell networking equipment. It directly replaces original Dell part numbers 02-SSC-8391-5M, 470-ACEW, and 470-ACEY, ensuring plug-and-play compatibility without additional configuration. The 5-meter length balances reach with signal integrity, making it perfect for inter-switch connections and equipment stacking scenarios. Advantages of Passive DAC Technology: Unlike active cables, passive DACs eliminate power consumption, reduce heat generation, and minimize failure points. This makes them ideal for high-density environments where thermal management is critical. The passive approach also reduces total cost of ownership while maintaining exceptional reliability. Compliance and Certifications: Fully RoHS compliant and adhering to EU Directive 2002/95/EC, this cable meets stringent environmental standards. UL and TUV safety certifications ensure it meets international quality benchmarks. Operating reliably between 0-70°C (32-158°F), it performs consistently across diverse data center environments. Warranty and Support: Backed by a comprehensive 90-day limited warranty, with free standard shipping on orders exceeding $99, this cable offers exceptional value. Custom brand programming is available for enterprise customers requiring OEM branding solutions. Ideal Applications: Data center networking, server interconnects, switch-to-switch connections, storage area networks, and high-performance computing environments benefit from this reliable connectivity solution.
