The JBX43779 40-meter LC/UPC to ST/APC simplex singlemode fiber patch cable is engineered for organizations requiring certified, high-reliability fiber optic connectivity. As a TAA-compliant product manufactured in compliance with RoHS/ELV directives, this cable meets stringent government procurement and environmental standards, making it ideal for federal and commercial installations. Technical Excellence: This singlemode fiber cable features a precision 9/125 micron core constructed from G.657.A1 glass fiber, providing superior bend radius characteristics and minimal signal degradation. The cable achieves exceptional performance metrics: insertion loss of ≤0.35dB (0.15dB typical), return loss ≥20dB, and attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. All performance specifications are tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Robust Construction: The 1.8mm outer diameter yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides excellent durability and flame resistance, suitable for installation in both riser and plenum environments. The simplex configuration with LC/UPC and ST/APC connectors enables reliable one-way signal transmission, with straight-through polarity ensuring consistent performance. Versatility and Customization: While this 40-meter configuration is available off-the-shelf, custom lengths are available upon request to meet specific deployment requirements. The cable ships from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC), ensuring rapid delivery. Standard orders over $99 qualify for free shipping. Applications: Ideal for fiber-to-the-home (FTTH), data center interconnects, telecommunications infrastructure, backbone networks, and any application requiring certified singlemode connectivity. The TAA compliance makes it particularly valuable for government, military, and security-sensitive installations. Warranty and Support: Backed by a 90-day limited warranty, this professional-grade cable represents a cost-effective solution for organizations requiring certified fiber optic infrastructure.
