The JBX92191 9-meter SC/ST duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. Engineered to exceed industry standards, this cable combines reliable performance with regulatory compliance. **Technical Specifications:** This singlemode fiber patch cable features a 9/125 micrometer core with G.657.A1 grade glass fiber, ensuring optimal light transmission and minimal signal degradation. The cable maintains low attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, supporting both C-band and L-band wavelengths. Insertion loss testing confirms performance at ≤0.35dB (0.15dB typical), while return loss measures ≥20dB, meeting rigorous telecommunications standards. **Connector Configuration:** Equipped with SC/UPC to ST/UPC connectors in Type A to B crossover polarity—the most common configuration for duplex patch cords. This standardized setup simplifies integration into existing network infrastructure without requiring additional adapters. **Compliance & Quality:** TAA compliant and RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets strict government procurement and environmental requirements. Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, it includes a 90-day limited warranty. **Construction & Durability:** The 1.8mm outside diameter cable features OFNR (Riser Rated) jacketing, providing fire-safety ratings suitable for vertical runs and general building installations. Manufactured in Taiwan, US, or China with quality control oversight, the cable withstands professional installation and long-term deployment. **Applications:** Ideal for telecommunications networks, data centers, campus area networks (CANs), and enterprise infrastructure requiring reliable singlemode fiber connectivity. The white color aids cable identification in dense installation environments. **Custom Options:** While this 9-meter configuration is standard, custom lengths are available for specific deployment needs. Free standard shipping applies on orders exceeding $99, with fast fulfillment from multiple US distribution centers.
