The JBX03443 is an enterprise-class active optical cable specifically engineered for high-speed network deployments requiring 40 gigabit connectivity. This 30-meter QSFP+ to 4x LC duplex breakout cable serves as an ideal replacement for Cisco's QSFP-4XLC-AOC30M, offering exceptional compatibility and performance in existing infrastructure. **Key Technical Specifications:** This cable features eight strands of OM3 50/125 multimode fiber optimized for 40GBASE-SR4 transmission standards (IEEE 802.3ba). The QSFP+ (Quad Small Form-factor Pluggable) connector breaks out to four individual LC duplex connectors, enabling flexible end-device connections without requiring separate media converters. The plastic-jacketed construction with LSZH (Low Smoke Zero Halogen) material provides both durability and safety compliance. **Compliance & Safety:** This AOC meets rigorous international standards including RoHS/ELV compliance, Class 1 Laser certification, and FDA regulations (21CFR 1040.10). Safety testing includes TUV and UL certification, ensuring safe operation in commercial and industrial environments. **Performance Advantages:** Active optical cables eliminate signal degradation over extended distances, making this 30-meter solution superior to passive copper alternatives. The OM3 multimode fiber supports bandwidth-intensive applications common in modern data centers, cloud infrastructure, and enterprise networks. Operating temperature range of 0-70°C ensures stable performance across diverse environmental conditions. **Installation & Compatibility:** Designed for Cisco-compatible equipment, this breakout cable simplifies network expansion by reducing the number of separate cable runs required. The integrated connectors eliminate termination labor, accelerating deployment timelines. Custom brand programming is available for OEM partnerships. **Warranty & Support:** Backed by a 90-day limited warranty, with convenient free standard shipping on orders exceeding $99.
