The JBX06386 5-meter HPE Compatible 25GBASE-CR SFP28 Passive Direct Attach Copper Cable represents an intelligent investment for organizations seeking reliable, cost-effective connectivity in modern data centers. This high-performance cable is engineered to deliver consistent 25Gbps data transmission over distances up to 5 meters, making it ideal for server-to-switch and switch-to-switch applications where optical solutions would be economically impractical. Construction and Materials: Built with 26AWG twinax copper conductors and protective plastic jacketing, the cable provides exceptional shielding and signal integrity. The dual copper conductors deliver superior electrical properties compared to standard copper cables, ensuring minimal signal loss and crosstalk interference even in densely populated patch panels. Compliance and Certification: This cable is fully qualified to IEEE 802.3by specifications and carries multiple safety certifications including RoHS, TUV, and UL compliance. These certifications guarantee compatibility with HPE equipment and adherence to international environmental standards. The cable replaces OEM part numbers 844480-B21, JL296A, and JL489A, providing seamless compatibility with existing HPE infrastructure. Technical Specifications: Operating across a temperature range of 0°C to 70°C (32°F to 158°F), the JBX06386 maintains consistent performance in various environmental conditions. The SFP28-to-SFP28 connector configuration ensures straightforward installation and secure connections. With dimensions of 12x12x5 inches and manufactured in Vietnam and China, the cable meets international quality standards. Value Proposition: Unlike active cables or optical modules, passive DAC cables require no power or complex configuration, reducing operational costs and simplifying network management. The 5-meter length strikes an optimal balance between coverage and signal quality, eliminating the need for expensive fiber infrastructure in short-reach scenarios. Warranty and Support: Backed by a 90-day limited warranty, customers enjoy peace of mind with their investment. Free standard shipping on orders exceeding $99 and availability from multiple U.S. locations (Danville, CA and Beaufort, SC) ensure quick delivery and accessibility. Custom brand programming is available for enterprise customers requiring specialized configurations. Applications: Ideal for hyperscale data centers, enterprise networks, and high-performance computing clusters where reliable, budget-conscious connectivity is essential. The JBX06386 eliminates the need for costly active transceivers while delivering professional-grade performance and reliability.
