The JBX05741 2.5m NVIDIA Mellanox Compatible 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents the gold standard in high-speed data center connectivity solutions. Designed specifically for organizations requiring robust, cost-effective alternatives to active cables, this passive DAC delivers enterprise-grade performance without compromise. Technical Specifications & Performance: This cable implements the 100GBASE-CR4 standard, supporting data rates up to 100 Gigabits per second. The 2.5-meter length is specifically optimized for typical data center rack-to-rack interconnections, eliminating signal degradation while maintaining exceptional signal-to-noise ratios. At 28AWG gauge, the twinax copper construction provides superior electrical properties and durability compared to thinner alternatives. Compatibility & Integration: Fully compatible with NVIDIA Mellanox networking infrastructure, this cable serves as a direct replacement for OEM part numbers 980-9I627-00E02A, 980-9I62I-00C02A, 980-9I62G-00C02A, and the complete MCP1600 series (MCP1600-C02AE30L, MCP1600-E02AE26, MCP1600-C02A). The QSFP28 form factor ensures seamless integration with modern high-performance switches and network interface cards from leading manufacturers. Certifications & Compliance: Rigorous testing and certification ensure deployment confidence. This cable meets IEEE 802.3bj specifications, QSFP28 MSA standards, and SFF-8665 compliance requirements. RoHS and ELV directives guarantee environmental responsibility, while TUV and UL safety certifications validate manufacturing excellence. EU directive 2002/95/EC compliance ensures regulatory adherence globally. Applications & Use Cases: Ideal for hyperscale data centers, high-frequency trading environments, cloud infrastructure deployments, and enterprise network upgrades. The passive design eliminates power consumption, heat generation, and potential single points of failure associated with active cables, reducing total cost of ownership while improving reliability. Customization & Support: Custom brand programming is available for volume deployments and enterprise OEM requirements. The 90-day limited warranty provides peace-of-mind protection.
