The JBX03846 15-meter Cisco-compatible QSFP28 active optical cable represents a premium solution for enterprise and data center networking infrastructure. This specialized breakout cable addresses the critical need for flexible 100GBASE-SR4 connectivity by seamlessly converting a single QSFP28 interface into four dedicated SFP28 ports, maximizing port utilization and reducing equipment costs. **Technical Specifications:** This cable utilizes OM3 50/125 multimode fiber with eight individual strands, engineered to support simultaneous 25GB per-channel transmission totaling 100GB aggregate bandwidth. The 15-meter length accommodates medium-distance intra-rack and cross-rack deployments common in enterprise data centers. The cable meets IEEE 802.3bm and QSFP28 MSA standards, ensuring compatibility with Cisco equipment and other standards-compliant infrastructure. **Safety and Compliance:** The LSZH (Low Smoke Zero Halogen) jacket with OFNR (Optical Fiber Non-Conductive Riser) rating provides superior fire performance in enclosed plenum spaces and cable trays. The cable holds Class 1 laser certification, TUV approval, and FDA compliance (21CFR 1040.10), meeting the most demanding safety requirements. Full RoHS/ELV directive compliance ensures environmental responsibility and regulatory adherence. **Performance Characteristics:** Operating reliably between 0-70°C (32-158°F), this cable handles diverse environmental conditions from temperature-controlled data center facilities to field installations. The robust plastic jacketing protects fiber strands from mechanical damage, EMI interference, and environmental hazards, extending service life in demanding applications. **Applications and Use Cases:** Ideal for high-speed data center interconnects, this cable supports virtualization environments, cloud infrastructure, storage area networks (SANs), and campus backbone networks. The breakout configuration is particularly valuable for network migrations, allowing organizations to gradually transition infrastructure without complete equipment replacement. **Care and Maintenance:** Handle with care to avoid excessive bending (minimum bend radius should be observed). Clean connectors with appropriate fiber-optic cleaning equipment before connections. Store in cool, dry conditions to preserve fiber integrity. The 90-day limited warranty covers manufacturing defects. **Value Proposition:** With free standard shipping on orders over $99 and custom brand programming available, this cable offers exceptional flexibility and cost efficiency. Direct manufacturer shipping from Danville, CA and Beaufort, SC ensures rapid delivery and local support for customers nationwide.
