The JBX03149 2-meter 200GBASE-SR4 QSFP-DD to 2x QSFP28 active optical cable represents a critical infrastructure component for next-generation data center deployments. This breakout AOC combines high-speed 200GB transmission capabilities with proven Arista compatibility, making it an ideal choice for organizations expanding network capacity. **Technical Specifications:** This cable features OM3 50/125 multimode fiber with 16 strands optimized for short-reach, high-bandwidth applications. The QSFP-DD (quad small form-factor pluggable double density) to 2x QSFP28 configuration enables flexible switching architectures, allowing data center operators to transition between different transceiver densities without complete infrastructure overhauls. **Performance & Reliability:** The active optical design incorporates precision electronics and low-latency signal processing, delivering consistent 200GBASE-SR4 performance within OM3 specifications. Operating across 0-70°C temperature ranges ensures reliable performance in both cooled and ambient data center environments. **Safety & Compliance:** Extensive certifications validate this cable's safety and environmental standards: RoHS/ELV compliance ensures hazard-free materials, LSZH jacketing minimizes toxic smoke in fire scenarios, and UL/FDA certifications guarantee electrical safety. Class 1 Laser and TÜV certifications demonstrate rigorous testing and quality assurance. **Installation & Compatibility:** Designed as a drop-in replacement for Arista AOC-D-2Q-200G-2M, this cable simplifies upgrades and expansions. The 2-meter length optimally spans standard data center rack spacing, reducing installation complexity. OFNR riser-rated construction permits installation in plenum spaces when wrapped appropriately. **Support & Warranty:** Backed by a 90-day limited warranty, with custom programming available for specialized deployments. Ships from strategic U.S. locations (Danville, CA and Beaufort, SC) enabling rapid delivery. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Whether upgrading existing infrastructure or deploying new high-density switching environments, the JBX03149 delivers enterprise-grade reliability, proven compatibility, and exceptional value for demanding network applications.
