The JBX43025 70-meter LC/APC to LC/UPC simplex fiber patch cable represents a premium solution for fiber optic connectivity in professional networking environments. This singlemode cable is engineered for telecommunications carriers, data centers, ISPs, and enterprise networks requiring reliable long-distance signal transmission. **Technical Excellence:** Featuring a 9/125 micrometer singlemode core, this cable delivers superior performance across standard telecommunication wavelengths. The insertion loss specification of ≤0.35dB at 1550nm and 0.25dB/km at 1310nm ensures minimal signal degradation over the full 70-meter span. With return loss ≥20dB, the cable minimizes signal reflections that could compromise network performance. **Compliance & Durability:** TAA compliance makes this cable ideal for government and enterprise procurement. The OFNR (Optical Fiber Non-conductive Riser) rating allows safe installation in vertical building pathways without conduit. The G.657.A1 glass fiber specification provides enhanced bend radius characteristics, improving installation flexibility while maintaining signal integrity. The yellow jacket protects against UV damage and provides clear visual identification in cable management systems. **Professional Installation:** The LC/APC (Physical Contact angled) to LC/UPC (Ultrapolished) connector pairing is standard in modern fiber networks, offering broad compatibility. The straight-through polarity configuration eliminates confusion during installation. At just 1.8mm outer diameter, the cable fits easily in existing conduit and cable trays. **Warranty & Support:** Backed by a 90-day limited warranty and manufactured in Taiwan, US, or China to ensure consistent quality. Custom lengths are available for specialized deployments. Ships from three US locations (California, Texas, South Carolina) with free standard shipping on orders over $99. **Applications:** Ideal for fiber backbone connections, telecommunications infrastructure, data center patch panels, FTTH (Fiber to the Home) networks, and long-distance signal transmission requiring premium performance and compliance certification.
