The JBX05018 800GBASE-CR8 QSFP-DD to 4x QSFP112 Direct Attach Copper (DAC) breakout cable represents cutting-edge networking infrastructure designed for demanding data center environments. This 1-meter cable delivers premium performance while maintaining cost-effectiveness through passive technology implementation. **Key Technical Features:** This breakout DAC utilizes high-quality 30AWG twinax copper conductors housed in protective plastic jacketing, ensuring optimal signal integrity over the full 1-meter span. The QSFP-DD to 4x QSFP112 configuration enables efficient port density multiplication, allowing single 800GB connections to expand into four independent 200GB+ pathways. Operating temperature range of 0-70°C ensures reliable performance across diverse data center conditions. **Compatibility & Performance:** Fully compatible with Arista networking equipment, this cable directly replaces OEM part C-D800-4Q200-1M. The passive breakout design eliminates active signal processing, reducing power draw, heat generation, and potential points of failure—critical advantages for mission-critical infrastructure. The cable maintains 800GBASE-CR8 compliance standards, ensuring seamless integration with existing network architectures. **Quality & Compliance:** Manufactured in Vietnam and China with rigorous quality controls, this cable meets international standards including RoHS compliance (EU directive 2002/95/EC), TUV certification, and UL safety requirements. The compact 12x12x2mm dimensions minimize cable bulk in high-density server racks. **Applications & Use Cases:** Ideal for hyperscale data centers, cloud service providers, financial trading platforms, and enterprise infrastructure upgrades. The breakout configuration supports flexible network topology changes without hardware replacement. **Warranty & Support:** Backed by a 90-day limited warranty and available for immediate shipment from Danville, CA or Beaufort, SC. Custom brand programming is available for OEM integrators. Free standard shipping applies to orders exceeding $99, making bulk network upgrades economical.
