The JBX05217 is a professional-grade 2-meter 40GBASE-CR4 QSFP+ to 4x SFP+ Direct Attach Copper (DAC) breakout cable designed for modern data center and enterprise network deployments. As a drop-in replacement for the Ruckus E40G-QSFP-4SFP-C-0201, this cable provides seamless compatibility with existing Ruckus network infrastructure. Technical Specifications: This active breakout DAC cable features QSFP+ (Quad Small Form-factor Pluggable) connectors on one end and four SFP+ (Small Form-factor Pluggable) connectors on the other. The 30AWG copper twinax construction ensures excellent signal integrity and minimal latency. At 2 meters, the cable length accommodates typical rack-to-rack and within-rack connectivity scenarios without excessive copper weight or cost. Standards Compliance: Qualified to IEEE 802.3ba specifications for 40 Gigabit Ethernet, the JBX05217 meets international regulatory requirements including RoHS (Restriction of Hazardous Substances) and EU Directive 2002/95/EC. TUV and UL certifications confirm safety and reliability standards. Operational Benefits: Direct Attach Copper cables eliminate the need for expensive transceiver modules, reducing total cost of ownership while maintaining exceptional performance. The wide operating temperature range (0-70°C) supports diverse deployment environments. This cable is ideal for breaking out a single 40G port into four 10G connections, enabling flexible network architecture and improved resource utilization. Applications: Perfect for data centers, cloud infrastructure, high-performance computing clusters, and enterprise networks requiring cost-effective 40G breakout connectivity. Commonly used in Ruckus ICX, CloudEngine, and similar switch deployments. Warranty & Support: Backed by a 90-day limited warranty. Free standard shipping on orders over $99. Ships from convenient U.S. locations (Danville, CA or Beaufort, SC) for fast delivery. Manufactured with precision in Vietnam and China, this cable delivers enterprise-grade reliability at competitive pricing.
