The JBX06492 represents a reliable and cost-effective solution for 25 gigabit ethernet networking requirements. This 3-meter Cisco-compatible SFP28 passive direct attach copper cable combines proven technology with enterprise-grade performance specifications. **Technical Excellence:** Built with 30AWG twinax copper conductors, this cable delivers consistent 25GBASE-CR performance over short to medium distances. The dual-conductor design minimizes electromagnetic interference while maintaining signal integrity across full-duplex communication channels. SFP28 connectors on both ends ensure secure, industry-standard connections compatible with Cisco and other leading networking equipment. **Performance Characteristics:** Qualified to IEEE 802.3by and SFF standards, the cable supports 25Gbps data rates with excellent signal quality. The passive design requires no external power supply, reducing operational complexity and heat generation in densely-populated equipment racks. **Compliance & Certification:** Full RoHS and TUV certification ensures compliance with global environmental standards. The cable meets EU directive 2002/95/EC requirements, making it suitable for regulated environments and international deployments. **Practical Applications:** Ideal for data center top-of-rack switching, server interconnections, and storage area network (SAN) deployments. The 3-meter length accommodates typical rack-to-rack distances while maintaining signal fidelity. Perfect for organizations upgrading legacy 10G infrastructure to modern 25GB speeds. **Reliability & Support:** Backed by a 90-day limited warranty and available through multiple U.S. shipping locations (Danville, CA and Beaufort, SC) with free standard shipping on orders over $99. Custom brand programming available for enterprise environments requiring standardized cable identification. **Why Choose This Cable:** With Cisco OEM compatibility and proven passive DAC technology, this cable eliminates vendor lock-in while delivering exceptional value. Lower cost than active DAC alternatives with superior reliability compared to longer copper runs, making it the optimal choice for modern data center infrastructure.
