The JBX89208 85m SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for critical network infrastructure. This cable combines extended length capability with precision engineering to meet demanding telecommunications and data center requirements. **Technical Excellence**: Built with 9/125 singlemode fiber core and G.657.A1 glass composition, this cable minimizes signal degradation across the entire 85-meter run. The measured attenuation rates—0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm—ensure excellent performance across standard telecom wavelengths. Return loss ≥20dB guarantees minimal signal reflection, critical for maintaining signal quality in long-distance applications. **Industry Compliance**: TAA (Trade Agreements Act) compliance and RoHS/ELV certification make this cable suitable for government projects, enterprise deployments, and environmentally-conscious organizations. OFNR riser rating provides fire safety for installations in building plenum spaces. **Practical Design Features**: The distinctive purple jacket enables quick identification in dense cable environments, reducing installation time and troubleshooting errors. The 1.8mm outer diameter maintains compatibility with standard cable management systems while providing robust protection. SC/UPC to ST/UPC connectors with Type A to B crossover configuration follow industry standards for duplex patch cords. **Quality Assurance**: Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent performance. The 90-day limited warranty demonstrates manufacturer confidence in product reliability. **Applications**: Ideal for telecommunications networks, data centers, campus networks, and any installation requiring extended single-mode reach with superior signal fidelity.
