The JBX05799 3-meter 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents the optimal balance of performance, reliability, and cost-effectiveness for modern high-speed networking environments. Designed specifically for Intel-compatible systems, this passive DAC cable delivers robust 100GB connectivity without requiring external power or active signal conditioning. **Technical Excellence** Manufactured to stringent IEEE 802.3bj and QSFP28 MSA specifications, this cable features precision-engineered 28AWG twinax copper conductors capable of maintaining signal integrity over its 3-meter length. The copper construction provides superior conductivity while the plastic jacketing offers protection against interference and physical damage. With a wide operating temperature range of 0-70°C (32-158°F), this cable performs reliably in diverse data center environments. **Key Benefits** Passive DAC technology eliminates the power draw associated with active solutions, reducing operational costs and heat generation in densely populated server racks. The straightforward QSFP28-to-QSFP28 copper connector design enables immediate installation without firmware updates or compatibility concerns. This cable directly replaces Intel OEM part numbers 100CQQF2830, XXLDACBL3M, and 100CQQH2830, ensuring seamless integration with existing infrastructure. **Compliance & Certifications** Full RoHS and ELV compliance meets EU Directive 2002/95/EC requirements, while TUV and UL safety certifications provide documented quality assurance. These certifications are essential for enterprise deployments requiring regulatory compliance documentation. **Ideal Applications** Deploy this cable in high-performance computing clusters, data center inter-switch links, server-to-storage connections, and other scenarios demanding reliable 100GB transmission within 3-meter distances. The passive design makes it particularly suitable for cost-conscious deployments without sacrificing performance. **Support & Warranty** Every JBX05799 includes a 90-day limited warranty and ships with free standard shipping on orders exceeding $99. Available from Danville, CA and Beaufort, SC distribution centers for rapid delivery. Custom brand programming available upon request for large-scale enterprise deployments.
