The JBX05184 QSFP+ to SFP+ Direct Attach Copper (DAC) breakout cable represents a cost-effective, high-performance solution for modern data center infrastructure. This 0.5-meter passive breakout cable is specifically engineered to support 40GBASE-CR4 connectivity while providing the flexibility to distribute high-speed signals across four separate SFP+ ports. Key Technical Features: This cable features premium 30AWG twinax copper conductors that deliver consistent 40GB data rates with minimal signal degradation. The passive breakout design eliminates active electronics, reducing power consumption and heat generation—critical factors in dense server environments. The QSFP+ form factor to 4x SFP+ configuration enables seamless integration with existing infrastructure while future-proofing your network investment. Compliance and Certification: Fully qualified to IEEE 802.3ba and SFF-8436 standards, the JBX05184 meets rigorous industry specifications for high-speed data transmission. RoHS, TUV, and UL certifications confirm adherence to environmental and safety directives, including EU directive 2002/95/EC. This makes it suitable for regulated industries and enterprise deployments requiring certified components. Extreme Networks Compatibility: Designed as a direct replacement for Extreme Networks part numbers 10GB-4-C0.5-QSFP, 10321-50C, and 40G-QSFP-4SFP-PC-0051, this breakout cable integrates seamlessly with Extreme Networks switching infrastructure. Its proven compatibility eliminates configuration concerns and simplifies procurement. Durability and Operating Conditions: With durable plastic jacketing and copper connectors, the cable withstands typical data center environments while operating reliably between 0-70°C (32-158°F). The compact 0.5m length is ideal for short-reach connections in server racks and switch-to-equipment installations. Value Proposition: Compared to active optical breakout solutions, this passive DAC cable offers significant cost savings without sacrificing performance. Compared to multiple individual cables, the unified breakout design reduces cable clutter and improves airflow in server cabinets. Custom brand programming is available for OEM and integration partners seeking private-label solutions. Availability and Support: Stocked and shipped from Danville, CA and Beaufort, SC locations, the JBX05184 qualifies for free standard shipping on orders exceeding $99. A 90-day limited warranty provides additional confidence in your purchase, backed by responsive customer support.
