The JBX03653 25m Arista Compatible 40GBASE-AOC QSFP+ Active Optical Cable represents the pinnacle of fiber optic connectivity solutions for modern enterprise and data center environments. Engineered to meet the stringent demands of high-speed network infrastructure, this cable delivers exceptional performance, reliability, and cost-effectiveness. **Technical Excellence:** This active optical cable features 8 strands of OM3 50/125 multimode fiber, specifically optimized for 40GB Ethernet transmission. The QSFP+ form factor ensures compatibility with current-generation switching equipment, while the 25-meter length provides ideal reach for intra-rack and inter-rack connectivity without degradation. IEEE 802.3ba certification guarantees standards-compliant operation across supported platforms. **Safety & Compliance:** The cable's LSZH (Low Smoke Zero Halogen) OFNR jacketing meets stringent fire codes and building regulations, making it suitable for plenum and riser installations. Comprehensive certifications include RoHS/ELV compliance, UL listing, FDA 21CFR 1040.10 adherence, and TUV approval. Class 1 Laser safety rating ensures equipment operator protection. **Arista Integration:** Precisely engineered for Arista switch compatibility, this cable serves as a direct replacement for OEM part AOC-Q-Q-40G-25M. The plug-and-play design eliminates compatibility concerns while maintaining optimal signal integrity and performance metrics. **Performance Characteristics:** Operating across the 0-70°C temperature range, this cable maintains consistent performance in varied environmental conditions. The plastic jacketing with fiber strands construction provides durability while minimizing installation footprint. 8-strand configuration ensures redundancy and signal stability. **Application Scenarios:** Ideal for high-density data center spine-leaf architectures, enterprise campus network upgrades, and service provider backbone connectivity. The 25-meter length accommodates both vertical and horizontal cable runs in multi-floor deployments. **Warranty & Support:** Backed by a 90-day limited warranty, this cable demonstrates manufacturer confidence in product quality. Custom brand programming available for OEM requirements. Manufactured in Vietnam and China with quality assurance standards. **Value Proposition:** When compared to traditional DAC (Direct Attach Copper) cables, AOCs provide superior reach without active signal conditioning. Versus longer-distance single-mode fiber solutions, multimode OM3 offers cost-effective performance for campus and data center deployments. Free standard shipping on orders exceeding $99 provides additional cost savings. Ships from dual U.S. distribution centers (Danville, CA and Beaufort, SC) ensuring rapid delivery availability.
