The JBX05762 2-meter HPE-compatible 100GBASE-CR4 QSFP28 passive DAC cable represents an ideal balance of performance, reliability, and value for enterprise and data center networking applications. This high-speed interconnect solution leverages proven copper twinax technology to deliver consistent 100GB Ethernet performance without the complexity or expense of active electronics. **Key Features & Specifications:** Constructed with premium 28AWG twinax copper conductors and protective plastic jacketing, this passive DAC cable maintains signal integrity across the full 2-meter length. The QSFP28 connector design (12×12mm form factor) provides a compact footprint suitable for high-density port configurations. Fully compliant with IEEE 802.3bj standards and QSFP28 MSA specifications, ensuring seamless integration with HPE switching infrastructure and compatible third-party equipment. **Certifications & Compliance:** This cable meets stringent international standards including RoHS (EU Directive 2002/95/EC), TUV, and UL safety certifications. These credentials provide assurance of product quality, environmental responsibility, and operational safety in mission-critical deployments. **Performance & Reliability:** Operating across the 0-70°C temperature range, the JBX05762 performs reliably in standard data center environments. The passive design eliminates external power dependencies, reducing complexity and potential failure points. This makes passive DAC cables particularly attractive for cost-conscious organizations seeking reliable 100GB connectivity without active transceiver overhead. **OEM Compatibility:** Directly replaces HPE part numbers 845404-B21-2M, R1N35A-2M, and 834973-B24, ensuring straightforward upgrades and cost savings compared to OEM pricing. Ideal for organizations maintaining HPE infrastructure while seeking compatible third-party alternatives. **Applications:** Perfect for top-of-rack switch-to-server connections, server-to-storage communications, and data center backbone networks requiring short-haul 100GB connectivity. The 2-meter length accommodates typical equipment spacing within standard server racks and cabinet deployments. **Warranty & Support:** Backed by a 90-day limited warranty and available through multiple US distribution centers (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99.
