The JBX85194 SC/ST Duplex Singlemode Fiber Patch Cable represents the gold standard in professional fiber optic connectivity. This 9-meter cable combines precision engineering with reliable performance, making it an essential component for any high-speed network deployment. **Technical Excellence:** Constructed with G.657.A1 glass fiber and a precision-engineered 9/125 micron core, this singlemode cable delivers superior signal integrity over extended distances. Tested to ANSI/TIA/EIA-455-171-A standards, it achieves exceptional performance metrics: insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB. Attenuation rates are optimized for both 1310nm and 1550nm wavelengths, supporting diverse applications from traditional telecom to modern coherent systems. **Superior Design Features:** The distinctive yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance and safety compliance while maintaining the cable's compact 1.8mm outside diameter. Type A to B crossover polarity (duplex configuration) ensures proper signal transmission in standard network installations. The plastic accessories and robust construction withstand demanding installation environments. **Compliance & Standards:** Full TAA (Trade Agreements Act) compliance makes this cable suitable for government and enterprise procurement. RoHS/ELV certification demonstrates commitment to environmental responsibility. The cable meets EU Directive 2002/95/EC requirements, ensuring worldwide compatibility. **Practical Benefits:** Available in custom lengths for specialized installations, this patch cable offers flexibility beyond the standard 9-meter configuration. Fast shipping from Danville CA, Fort Worth TX, or Beaufort SC locations ensures rapid deployment. The 90-day limited warranty provides peace of mind for critical network applications. **Ideal Applications:** Perfect for data center interconnects, telecommunications infrastructure, enterprise LAN upgrades, and fiber-to-the-premises installations. The singlemode architecture supports long-distance transmission with minimal signal degradation, making it suitable for campus networks and metropolitan area networks. Invest in reliable fiber connectivity with specifications that exceed industry standards.
