The JBX03853 represents premium interconnect technology for next-generation data center and enterprise networking environments. As a 1-meter 100GBASE-SR4 QSFP28 to 4x SFP28 active optical breakout cable, it bridges the gap between high-capacity uplinks and individual port requirements with exceptional performance and reliability. **Technical Specifications:** This breakout AOC utilizes 8-strand OM3 50/125 multimode fiber, delivering 100GB aggregate bandwidth across four SFP28 connections. The LSZH (Low Smoke Zero Halogen) jacketing with OFNR (Optical Fiber Non-conductive Riser) rating ensures compliance with building codes and safety standards for plenum and non-plenum installations. Dimensions of 12x12x2mm provide compact integration within equipment bays. **Performance & Compatibility:** Qualified to IEEE 802.3bm and QSFP28 MSA specifications, this cable guarantees seamless compatibility with Arista switches and other certified equipment. The active optical design eliminates signal degradation over the 1-meter distance, making it ideal for top-of-rack and modular deployment scenarios. **Regulatory Compliance:** Full RoHS/ELV directive compliance (EU 2002/95/EC) with Class 1 Laser certification, TUV verification, and UL/FDA certification per 21CFR 1040.10 ensures deployment in regulated environments. The cable directly replaces Arista AOC-Q-4S-100G-1M specifications. **Applications:** Perfect for high-density data center switching, server interconnects, storage arrays, and enterprise switching fabrics. Supports 0-70°C operating temperatures for reliable performance in climate-controlled facilities. **Shipping & Support:** Qualifies for free standard shipping on orders exceeding $99. Custom brand programming available for enterprise customers. Backed by 90-day limited warranty. Manufactured in Vietnam and China with U.S.-based distribution from Danville, CA and Beaufort, SC locations.
