The JBX43254 LC/APC to ST/UPC singlemode fiber patch cable represents a professional-grade solution for fiber optic network infrastructure. This 15-meter simplex cable combines precision engineering with proven reliability, making it ideal for telecommunications facilities, data centers, and enterprise network installations. **Key Technical Specifications:** Constructed with 9/125 singlemode glass fiber (G.657.A1), this cable delivers exceptional optical performance. The ultra-low insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation over transmission distances. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm provide consistent performance across standard operational wavelengths. **Connector Excellence:** The LC/APC connector offers superior signal quality with its angled physical contact design, while the ST/UPC termination ensures broad compatibility with existing network infrastructure. The straight-through polarity design simplifies installation and reduces configuration errors. **Durability & Compliance:** The 1.8mm outside diameter OFNR riser-rated yellow jacket provides flame resistance and durability in demanding environments. TAA compliance and RoHS/ELV certification satisfy government procurement requirements and environmental standards. Manufacturing capabilities in Taiwan, US, and China ensure consistent quality and global supply chain reliability. **Practical Applications:** Ideal for connecting fiber optic equipment in data centers, telecommunications hubs, and campus networks. The distinct yellow jacket simplifies cable management and identification. Custom length availability accommodates specific installation requirements. Available in bulk packaging (10x10x10 case) for enterprise deployments. **Warranty & Support:** Backed by a 90-day limited warranty with free standard shipping on orders exceeding $99, shipped from strategically located facilities in California, Texas, or South Carolina.
