The JBX85197 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for demanding network environments. Built with 15 meters of 9/125 singlemode fiber wrapped in a durable 1.8mm diameter yellow OFNR-rated jacket, this cable delivers reliable performance across critical applications. **Technical Excellence** This patch cable utilizes G.657.A1 fiber specification, ensuring compatibility with modern network infrastructure while maintaining superior optical characteristics. The SC/UPC to ST/UPC connectors feature Type A to B crossover polarity—the most common configuration for duplex patch cords—eliminating compatibility concerns. Insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards, providing clean signal transmission with minimal signal degradation. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support both traditional and long-wavelength applications. **Compliance & Standards** TAA compliance makes this cable suitable for government and regulated sector deployments. The cable meets RoHS Directive 2002/95/EC and EU environmental standards, reflecting commitment to sustainable manufacturing. OFNR (Optical Fiber, Non-conductive, Riser) rating permits installation in riser spaces between building floors without conduit, streamlining deployment in multi-story facilities. **Practical Advantages** The distinctive yellow jacket provides immediate visual identification on dense patch panels, reducing installation errors and maintenance time. The cable ships from multiple U.S. locations (Danville, Fort Worth, Beaumont) ensuring rapid delivery, with free standard shipping on orders exceeding $99. Custom lengths are available for non-standard requirements. **Applications** Ideal for telecommunications infrastructure, data center backbone networks, enterprise campus networks, and long-distance signal transmission. Perfect for organizations requiring TAA-compliant equipment or operating in regulated environments. **Quality Assurance** Each cable is attenuation-tested per ANSI/TIA/EIA-455-171-A standards and includes 90-day limited warranty coverage. Manufactured to stringent quality specifications in Taiwan, United States, or China facilities, ensuring consistent performance across production runs. Invest in reliable, standards-compliant fiber connectivity with the JBX85197 patch cable—engineered for performance, built for compliance, designed for your network's future.
