The JBX43181 LC/APC to FC/UPC simplex singlemode fiber patch cable represents industrial-grade connectivity engineered for mission-critical applications. This 1-meter cable combines precision connector technology with high-performance 9/125 singlemode fiber to ensure reliable, low-loss signal transmission in telecommunications, data center, and enterprise network environments. **Technical Specifications:** This cable features 9/125 singlemode fiber with G.657.A1 glass characteristics, providing superior bend performance while maintaining excellent optical properties. The 1.8mm outer diameter offers durability and ease of routing in tight spaces. Insertion loss is rated at ≤0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB, ensuring minimal signal reflection and optimal transmission quality. **Connector Technology:** The LC/APC connector features angled polishing for superior return loss performance, while the FC/UPC connector provides reliable screw-on connectivity. This simplex configuration transmits signals in one direction, ideal for unidirectional applications or when paired with complementary cables for full-duplex communication. **Compliance & Standards:** TAA (Trade Agreements Act) compliant design qualifies this cable for government and institutional purchasing. RoHS/ELV directive compliance ensures environmental responsibility. All cables undergo rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance across temperature ranges. **Installation & Performance:** The OFNR (Optical Fiber Non-Conductive Riser) rating allows safe installation in vertical runs within building risers without conduit. The yellow jacket provides excellent visibility during installation and maintenance. Attenuation specifications (0.25 dB/km @ 1310nm, 0.35 dB/km @ 1550nm) ensure minimal signal degradation over distance, critical for long-span installations. **Flexibility & Customization:** While this product ships at 1 meter standard length, custom lengths are available to match your specific deployment requirements, reducing waste and simplifying inventory management. **Support & Warranty:** Backed by a 90-day limited warranty and shipped from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC), this cable combines quality assurance with fast, reliable delivery. Free standard shipping on orders exceeding $99 makes bulk purchases economical.
