The JBX05541 represents a premium solution for organizations requiring robust 100GB connectivity in high-performance computing and data center environments. This 0.5-meter 100GBASE-CR4 QSFP28 to dual QSFP28 direct attach copper cable combines exceptional performance with enterprise-grade reliability. **Technical Specifications & Performance** Engineered to IEEE 802.3bj standards and QSFP28 MSA specifications, this passive DAC cable supports full 100GB data transmission rates without active electronics. The 30AWG twinax copper construction ensures minimal signal loss over short distances while reducing power consumption compared to active alternatives. Operating temperature range of 0-70°C accommodates most data center thermal profiles. **Connectivity & Compatibility** Designed as a direct replacement for NVIDIA Mellanox 980-9I61D-00C001 and comparable part numbers (MCP7H00-G00AR30N, MCP7H00-G00A), this cable integrates seamlessly into existing Mellanox infrastructure. The dual QSFP28 breakout configuration supports versatile network architectures while maintaining compact packaging. **Quality & Compliance** RoHS, TUV, and UL certifications ensure compliance with international safety and environmental standards. EU directive 2002/95/EC (RoHS) compliance eliminates hazardous substances. Premium plastic jacketing provides durability and flexibility for installation in confined spaces. **Ideal Applications** Perfect for high-speed interconnects in: data center switch-to-server connections, storage area network (SAN) implementations, high-performance computing clusters, and enterprise backbone networks. Short 0.5m length suits rack-mounted deployments with minimal cable management complexity. **Value Proposition** As a passive DAC solution, it eliminates active component costs while delivering deterministic latency and zero power overhead. Comprehensive 90-day warranty and free standard shipping on orders exceeding $99 provide additional customer protection and cost savings.
