The JBX05186 40GBASE-CR4 QSFP+ to SFP+ breakout DAC cable is engineered for high-performance data center environments requiring reliable, high-speed interconnectivity. This 0.5-meter passive direct attach copper cable serves as a compatible alternative to Juniper's original QFX-QSFP-DACBO-50CM part, delivering identical performance at competitive pricing. Key Features: Passive Breakout Architecture: Eliminates active components, reducing heat generation and power consumption while maintaining signal integrity. The cable converts one 40G QSFP+ connection into four independent 10G SFP+ channels, providing flexible port utilization across legacy and modern network infrastructure. Coppper Construction & Standards Compliance: Constructed with 30AWG twinax copper conductors and protective plastic jacketing, the cable meets stringent IEEE 802.3ba specifications. Full compliance with RoHS and EU Directive 2002/95/EC ensures environmental responsibility and regulatory adherence across global markets. Robust Certification: Qualified by TUV and UL certifications, this cable undergoes rigorous testing for safety and performance reliability. The 90-day limited warranty provides peace of mind for your infrastructure investment. Operational Excellence: Rated for 0-70°C operating temperatures, the cable performs consistently in demanding data center conditions. The compact 0.5-meter length is ideal for equipment racks and cabinet interconnections where space constraints require efficient cable management. Applications & Use Cases: Data Center Infrastructure: Perfect for top-of-rack switches, storage systems, and high-performance computing environments requiring burst connectivity. The passive design eliminates latency concerns critical for database replication and real-time analytics. Network Upgrades: Retrofit existing QSFP+ equipped hardware with SFP+ modules without expensive hardware replacement. Maximize return on infrastructure investments while maintaining performance standards. Edge Computing: Deploy in remote facilities, branch offices, and edge locations where passive components ensure reliability without additional cooling or maintenance requirements. Customization Available: The product supports custom brand programming for enterprises requiring OEM-branded solutions, making it suitable for resellers and systems integrators. Shipping & Support: Fast delivery from U.S. warehouses in California and South Carolina ensures quick order fulfillment. Orders exceeding $99 qualify for free standard shipping, providing exceptional value for volume purchases common in enterprise deployments.
