The JBX03727 50-meter Arista-compatible 40GBASE-AOC QSFP+ active optical cable represents a critical infrastructure component for modern data center networks requiring high-speed, reliable interconnectivity. This advanced active optical cable (AOC) solution combines proven fiber optic technology with integrated electronics to deliver exceptional performance and longevity. **Technical Specifications:** This cable utilizes OM3 50/125 multimode fiber with 8 strands, providing optimal signal integrity over 50-meter distances. The QSFP+ form factor ensures universal compatibility across Arista switches and transceivers, while supporting full 40GB/s data rates per IEEE 802.3ba standards. The cable measures 12x12x50mm and weighs significantly less than traditional copper alternatives, reducing thermal load in densely populated patch panels. **Superior Construction Quality:** Manufactured in Vietnam and China using premium materials, this AOC features plastic jacketing with OFNR (Optical Fiber Non-conductive Riser) rating, meeting stringent building codes for vertical runs and enclosed spaces. The construction incorporates Class 1 Laser technology with comprehensive safety certifications including UL, FDA 21CFR 1040.10, and TUV compliance. RoHS and ELV directive compliance ensures environmental responsibility and regulatory adherence. **Performance Advantages:** Active optical cables eliminate the signal degradation inherent in longer copper runs, enabling reliable 40GB connections without regeneration. The integrated optics automatically compensate for environmental variations, maintaining performance across the full 0-70°C operating temperature range. This cable replaces OEM part AOC-Q-Q-40G-50M, offering superior value without compromise. **Deployment Applications:** Ideal for enterprise data centers, high-performance computing clusters, and service provider networks requiring dense, high-speed interconnects. The 50-meter length accommodates expansive campus-scale deployments while maintaining signal fidelity. Custom brand programming availability enables seamless integration into existing network inventories. **Warranty & Support:** Backed by a 90-day limited warranty with responsive customer support. Shipped from multiple U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, ensuring rapid deployment and minimal downtime.
