The JBX06447 1m 25GBASE-CR SFP28 Passive Direct Attach Copper Cable represents an essential component for modern high-speed networking infrastructure. This Intel-compatible cable is engineered to deliver reliable 25GB per second data transmission, making it ideal for data centers, cloud computing environments, and enterprise networks requiring high-bandwidth connectivity. Construction and Materials: Featuring robust 30AWG twinax copper construction with protective plastic jacketing, this passive DAC cable eliminates the need for active electronic components found in active direct attach cables. The copper connectors and twinax design minimize signal degradation over short distances, ensuring optimal performance without additional power requirements or heat generation. Compliance and Certification: This cable meets stringent industry standards including IEEE 802.3by, SFF-8402, and SFF-8472 specifications. RoHS and ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility and safety. UL and TUV certifications further validate its quality and reliability for enterprise deployments. Performance Specifications: With a 1-meter length optimized for rack-to-rack and short-reach connections, the cable operates reliably across a 0-70°C temperature range. Its compact 12x12x2mm dimensions ensure minimal footprint in crowded network environments. The cable supports 25GBASE-CR protocol, delivering consistent performance in demanding networking scenarios. Compatibility and Replacement: Designed as a direct replacement for OEM part number XXVDACBL1M, this cable integrates seamlessly with Intel-compatible network infrastructure. It works with all standard SFP28 transceivers and switches supporting 25GB connectivity. Value Proposition: Unlike active DAC alternatives, this passive cable requires no power management, reducing operational complexity and costs. Its proven reliability, combined with a 90-day limited warranty and free standard shipping on orders over $99, makes it an economical choice for network infrastructure upgrades and maintenance.
