The JBX03845 is a professional-grade 15-meter 100GBASE-SR4 QSFP28 active optical cable engineered specifically for Arista-compatible network deployments. This breakout AOC cable represents the ideal solution for organizations seeking to maximize port density while maintaining exceptional signal quality and network performance. **Key Features & Benefits:** The QSFP28 to 4x SFP28 breakout architecture enables unprecedented flexibility in network design. A single QSFP28 port can be expanded into four independent SFP28 connections, dramatically increasing the number of available network interfaces without requiring additional physical infrastructure. This is particularly valuable in data centers where space and cooling constraints are critical. **Advanced Fiber Technology:** Constructed with OM3 50/125 multimode fiber strands, this cable supports 100GB data transmission across 15 meters with excellent signal integrity. The multimode fiber provides superior performance for short to medium distance applications while maintaining cost-effectiveness compared to single-mode alternatives. Eight fiber strands ensure optimal redundancy and signal distribution. **Safety & Compliance:** Featuring LSZH (Low Smoke Zero Halogen) OFNR-rated jacketing with plastic jacketing materials, this cable meets stringent fire and smoke emission standards required by most data center facilities. Complete compliance with RoHS/ELV directives, EU 2002/95/EC, and safety certifications including Class 1 Laser, TUV, and UL/FDA (21CFR 1040.10) ensure reliability and regulatory adherence. **Technical Specifications:** Qualified to IEEE 802.3bm and QSFP28 MSA standards, this cable delivers 100GB performance with operating temperatures from 0°C to 70°C (32°F to 158°F). The direct replacement for Arista's AOC-Q-4S-100G-15M part number ensures guaranteed compatibility and performance. **Applications & Use Cases:** Ideal for enterprise data centers, cloud infrastructure deployments, high-performance computing clusters, and service provider networks requiring high-capacity interconnects. Perfect for server-to-switch and switch-to-switch connections in modern virtualized environments. **Warranty & Support:** Backed by a 90-day limited warranty and custom brand programming available. Ships free on orders over $99 from Danville, CA and Beaufort, SC locations, ensuring fast delivery to your facility.
