The JBX43612 FC/APC to ST/UPC 10-meter simplex fiber patch cable represents a reliable solution for professional fiber optic installations requiring precise connector compatibility and exceptional performance. Engineered for telecommunications, data centers, and network infrastructure environments, this cable delivers industry-leading optical specifications and compliance certifications. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this patch cable achieves outstanding performance metrics. The insertion loss rating of ≤0.35dB (0.15dB typical) and return loss of ≥20dB meet stringent telecommunications standards. The cable maintains consistent attenuation of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm, ensuring reliable long-distance signal transmission. **Build Quality & Safety:** Feturing a 1.8mm outer diameter with OFNR riser-rated jacketing, the cable meets fire safety requirements for commercial building installations. The robust plastic accessory construction ensures durability while the yellow coloring provides clear visual identification in complex cable management scenarios. **Compliance & Standards:** Fully TAA compliant and RoHS/ELV directive certified, this cable meets EU directive 2002/95/EC requirements. Manufacturing follows ANSI/TIA/EIA-455-171-A-2001 standards with comprehensive attenuation testing. The straight-through polarity configuration ensures seamless connectivity. **Practical Advantages:** Available in custom lengths beyond the standard 10-meter configuration, this cable accommodates diverse installation requirements. Comprehensive warranty protection and multiple domestic shipping locations ensure rapid delivery and customer support. The simplex design provides straightforward single-direction transmission, eliminating unnecessary complexity in applications requiring unidirectional signal flow. **Ideal Applications:** Perfect for connecting single-strand fiber runs, telecommunications equipment, network switches, and optical testing equipment where FC/APC and ST/UPC connector compatibility is essential.
