The JBX42266 75-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents premium connectivity for mission-critical network infrastructure. This professional-grade cable is engineered to deliver reliable, high-speed fiber optic signal transmission across extended distances without signal degradation. **Technical Excellence:** Built with 9/125 singlemode fiber and G.657.A1 glass specifications, this cable achieves industry-leading attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Insertion loss remains minimal at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB—ensuring optimal signal integrity. The cable has been attenuation tested in strict accordance with ANSI/TIA/EIA-455-171-A standards. **Connector Configuration:** The LC/APC to ST/UPC configuration with Type A to B crossover polarity represents the most common duplex patch cord setup, making it immediately compatible with existing infrastructure. LC connectors provide superior performance characteristics, while ST connectors ensure broad legacy system compatibility. **Durability & Compliance:** The 1.8mm outside diameter with OFNR riser-rated jacketing meets building safety codes while protecting against environmental stress. TAA compliance ensures it meets federal procurement standards for government and institutional buyers. Full RoHS/ELV certification confirms environmental responsibility. **Practical Applications:** Ideally suited for data centers, enterprise networks, telecom installations, and campus area networks (CANs). The 75-meter length eliminates the need for multiple shorter cables while maintaining signal quality. **Value & Support:** Ship from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) enables fast delivery. Free standard shipping on orders exceeding $99 reduces procurement costs. Custom lengths are available for specialized installations. Backed by a comprehensive 90-day limited warranty. **Care Recommendations:** Protect connectors with dust caps when not in use. Avoid sharp bends or crushing force. Store in a cool, dry environment away from direct sunlight.
