The JBX06409 25GBASE-CR SFP28 passive direct attach copper cable represents an essential component for modern high-speed network deployments. Designed to replace OEM part numbers JNP-SFP-25G-DAC-50CM and SFP-25G-DAC-50CM, this 0.5-meter cable delivers exceptional performance for Juniper-compatible network equipment. **Key Features & Specifications:** This cable utilizes premium 30AWG twinax copper construction, engineered to support 25Gbps data rates with minimal latency and signal degradation. The SFP28 connectors on both ends ensure reliable, tool-free connections that integrate seamlessly with existing infrastructure. Operating reliably across temperatures from 0°C to 70°C (32°F to 158°F), it performs consistently in diverse data center environments. **Compliance & Standards:** Fully certified to IEEE 802.3by specifications and qualified under SFF-8402 and SFF-8472 standards, ensuring maximum compatibility and reliability. RoHS and ELV compliant with TUL and UL safety certifications, meeting all major environmental and safety directives including EU directive 2002/95/EC. **Performance Advantages:** As a passive DAC solution, this cable eliminates the need for external power, reducing energy consumption and operational costs while delivering wire-speed performance. The short 0.5-meter length makes it ideal for densely populated server racks, where cable management is critical. Perfect for direct server-to-switch, switch-to-switch, and switch-to-storage connections in enterprise data centers. **Quality & Support:** Backed by a 90-day limited warranty and available with custom brand programming. Ships from multiple US locations (Danville, CA and Beaufort, SC) with free standard shipping on qualifying orders. Custom solutions available for large deployments or specialized requirements.
