The JBX06425 1.5m HPE-compatible 25GBASE-CR SFP28 passive direct attach copper cable represents the ideal solution for enterprises seeking reliable, cost-effective high-speed network connectivity. Engineered to meet the demanding requirements of modern data centers, this twinax cable delivers consistent 25GB performance while maintaining the lowest total cost of ownership among comparable solutions. **Technical Specifications:** Built to IEEE 802.3by and SFF-8402/8472 standards, this passive DAC cable features precision-engineered SFP28 copper connectors that ensure flawless signal integrity. The 30AWG twinax construction provides optimal impedance matching and electromagnetic shielding, critical for maintaining data integrity over extended use periods. Operating temperature range of 0-70°C (32-158°F) accommodates diverse deployment environments from cooled data centers to warm equipment closets. **Performance & Reliability:** Unlike active DAC cables, this passive design eliminates power dependency and associated failure points, resulting in superior long-term reliability. The 1.5-meter length is ideal for intra-rack and adjacent-rack connections, the most common deployment scenario in data center architectures. With zero power consumption, this cable reduces operational expenses while delivering consistent 25GB throughput. **Compliance & Certification:** Fully RoHS and ELV compliant, this cable meets stringent environmental and safety standards (RoHS, TUV, UL certifications). It's manufactured to exacting specifications in Vietnam and China, ensuring consistent quality across every unit. **HPE Compatibility:** Direct replacement for OEM part numbers 844474-B21-150CM and JL294A-1-5M, this cable integrates seamlessly into existing HPE infrastructure. Compatible with HPE Arista, Cisco, and other major networking equipment supporting 25GBASE-CR SFP28 connections. **Ideal Applications:** • Data center switch interconnection • Storage array to compute node connectivity • High-performance computing clusters • Network backbone optimization • Cost-effective 25GB upgrade solutions **Included Warranty:** All units ship with a comprehensive 90-day limited warranty. Free standard shipping on orders exceeding $99, with convenient fulfillment from Danville, CA or Beaufort, SC locations.
