The JBX92190 SC/ST duplex singlemode fiber patch cable represents enterprise-level connectivity engineered for telecommunications and data center applications. Measuring 8 meters in length, this cable bridges network equipment with minimal signal loss and maximum reliability. **Technical Excellence:** Built with 9/125 singlemode fiber core and G.657.A1 glass specifications, this cable delivers attenuation rates of just 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths. The measured insertion loss of ≤0.35dB (typically 0.15dB) and return loss of ≥20dB ensure signal integrity across long transmission distances. These specifications comply with ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance in critical network environments. **Connector Compatibility:** Features SC/UPC to ST/UPC connectors with Type A to B crossover polarity—the most common configuration for duplex patch cords. This duplex design houses two fiber strands in one flexible cable, streamlining installations while maintaining individual fiber strand isolation. **Installation & Safety Features:** The 1.8mm outer diameter enables flexible routing through conduit and cable trays without compromising signal quality. OFNR riser-rated jacketing ensures fire safety compliance for in-building installations. The white jacket provides excellent visibility for cable identification and organization. **Compliance & Availability:** TAA-compliant for government and institutional procurement requirements. RoHS and ELV directive compliant for environmental responsibility. Custom lengths are available to meet specific installation requirements. Ships from multiple US locations with free standard shipping on orders over $99. **Ideal Applications:** • Telecommunications infrastructure upgrades • Data center interconnects • Enterprise campus networks • Government and institutional networks • Long-distance signal transmission • Carrier-grade deployments Backed by a 90-day limited warranty, this professional-grade patch cable delivers the performance and reliability demanded by mission-critical network installations.
