The JBX06153 0.5m HPE BladeSystem 10GBASE-CR SFP+ Passive Direct Attach Copper Cable represents an essential component for modern data center infrastructure. This professional-grade network interconnect is engineered specifically for HPE BladeSystem compatibility, delivering 10Gbps bandwidth through high-quality twinax copper construction. **Key Technical Specifications:** This cable utilizes 30AWG twinax copper conductors wrapped in protective plastic jacketing, providing excellent electromagnetic shielding and signal integrity. The dual SFP+ connectors ensure secure, tool-free installation on compatible network interfaces. At just 0.5 meters in length, this cable is optimally sized for blade chassis interconnections and adjacent equipment connections, minimizing cable clutter while maintaining performance. **Performance & Reliability:** Qualified to IEEE 802.3ae and SFF-8431/SFF-8472 standards, this passive DAC (Direct Attach Cable) requires no external power supply, reducing complexity and potential failure points. Operating temperatures span 0-70°C, accommodating diverse data center environments. The cable is fully RoHS and ELV compliant per EU Directive 2002/95/EC, with additional UL and TUV safety certifications. **HPE Compatibility:** Designed as a drop-in replacement for HPE OEM part number 487649-B21, this cable integrates seamlessly into existing HPE BladeSystem environments. Its SFP+ form factor ensures compatibility across HPE networking hardware supporting 10GBASE-CR standards. **Applications:** Ideal for high-density blade server deployments, SAN fabric connections, and short-reach backbone links within data centers. The 0.5m length is particularly suited for equipment in close proximity, such as server blade-to-switch or server-to-storage connections. **Advantages Over Alternatives:** Compared to longer cables or active solutions, passive DACs like this offer superior performance, lower latency, reduced power consumption, and minimal heat generation. This makes them the preferred choice for environmentally conscious enterprises and power-optimized data centers. Backed by a 90-day limited warranty and available with custom brand programming, this cable delivers professional-grade reliability with exceptional value.
