The JBX43507 ST/APC to ST/UPC simplex singlemode fiber patch cable represents premium connectivity for professional fiber optic networks. This 80-meter cable combines precision engineering with reliable performance, making it an essential component for telecommunications infrastructure, data centers, and broadcast operations. **Technical Excellence**: Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable meets rigorous performance standards. The insertion loss specification of ≤0.35dB (with typical 0.15dB) and return loss of ≥20dB ensures minimal signal degradation over extended distances. Independent testing confirms attenuation of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, supporting both traditional and modern wavelength transmission. **Durability and Compliance**: The yellow OFNR-rated (Optical Fiber Non-conductive Riser) jacket provides excellent flame resistance, making this cable ideal for building plenum and riser installations. TAA compliance ensures this product meets Buy American Act requirements, qualifying for government and enterprise procurement programs. RoHS and ELV directive compliance demonstrates commitment to environmental standards. **Practical Advantages**: The compact 1.8mm outside diameter minimizes cable bulk while the straight-through simplex design simplifies installation. Custom lengths are available for specific project requirements. Pre-tested assemblies eliminate field termination errors, reducing installation time and ensuring consistent performance. **Applications**: Perfect for long-distance fiber runs in telecommunications networks, high-speed data center interconnections, CATV systems, and broadcast facilities. The ST/APC to ST/UPC configuration accommodates mixed connector environments common in upgraded network infrastructure. **Support and Service**: Each cable includes a 90-day limited warranty. Free standard shipping on orders over $99 reduces total cost of ownership. Available from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for quick delivery.
