The JBX06465 25GBASE-CR SFP28 passive direct attach copper cable represents a cost-effective, high-performance solution for modern data center and enterprise networking deployments. Engineered to IEEE 802.3by and SFF specifications, this 2.5-meter cable delivers reliable 25GB ethernet connectivity with minimal signal degradation across short-reach applications. **Technical Excellence**: The cable's 30AWG twinax copper construction provides optimal impedance matching and signal fidelity. As a passive DAC (direct attach copper), it requires no power amplification or active components, resulting in lower operational costs, reduced heat output, and simplified deployment compared to active alternatives. This passive design makes it ideal for budget-conscious installations without compromising performance. **Intel Compatibility & Standards Compliance**: Specifically qualified for Intel networking infrastructure, this cable integrates seamlessly with compatible switches, NICs, and network equipment. Full compliance with IEEE 802.3by, SFF-8402, and SFF-8472 standards ensures interoperability and long-term reliability. The cable replaces OEM part number XXVDACBL250CM. **Durability & Certification**: Constructed with protective plastic jacketing and manufactured in Vietnam or China, this cable features comprehensive safety approvals including RoHS, TUV, and UL certifications. It meets EU directive 2002/95/EC environmental standards, supporting corporate sustainability initiatives. **Performance Specifications**: Supporting 25GB data rates across its 2.5m length, the cable operates reliably within 0-70°C temperature parameters, suitable for standard indoor data center environments. The compact 12x12x3mm form factor ensures compatibility with standard rack-mounted infrastructure. **Warranty & Support**: All units include a 90-day limited warranty. Available from Danville, CA and Beaufort, SC distribution centers with free standard shipping on qualifying orders. Custom brand programming is available for volume deployments. **Ideal Applications**: Perfect for server-to-switch connections, storage area networks, and high-performance computing clusters where 25GB connectivity is essential. The 2.5m length accommodates typical rack-to-rack distances while the passive design provides cost advantages over active alternatives for latency-sensitive applications.
