The JBX43419 SC/APC to ST/APC simplex singlemode fiber patch cable represents the gold standard in optical connectivity solutions for professional networking environments. With a generous 90-meter length, this cable is ideal for campus networks, data center interconnects, and long-distance point-to-point fiber links. **Technical Excellence** Constructed with 9/125 singlemode core and G.657.A1 high-performance glass fiber, this cable delivers superior attenuation characteristics: 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. The simplex configuration provides straightforward unidirectional signal transmission, while APC connectors offer exceptional optical performance with return loss exceeding 20dB, crucial for minimizing signal degradation in long-distance applications. **Build Quality and Compliance** The cable features OFNR riser-rated jacketing suitable for in-building installations, with a compact 1.8mm outside diameter enabling flexible routing through constrained spaces. TAA compliance ensures this cable meets Buy American Act requirements, while RoHS/ELV certification confirms environmental responsibility. All attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance across installations. **Applications and Use Cases** Ideal for telecommunications infrastructure, enterprise data centers, research institutions, and government facilities requiring compliant networking solutions. The yellow outer jacket provides visual identification in complex cable environments, improving network management and troubleshooting efficiency. **Flexibility and Support** Custom lengths are available for specialized installation requirements, allowing network engineers to optimize cable runs without excess material waste. The 90-day limited warranty provides peace of mind, backed by rapid shipping from strategically located US warehouses. Free standard shipping applies to orders exceeding $99, reducing total acquisition costs for bulk installations. Whether upgrading existing fiber infrastructure or deploying new networks, the JBX43419 delivers reliability, performance, and compliance in a single, cost-effective solution.
