The JBX85193 8-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking infrastructure. Designed specifically for single-mode applications requiring exceptional signal fidelity, this cable delivers industry-leading performance specifications suitable for telecommunications carriers, data centers, and enterprise networks. **Technical Excellence** Constructed with a 9/125 micrometer singlemode fiber core and G.657.A1 glass fiber, this cable achieves remarkable transmission characteristics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) minimizes signal degradation, while return loss exceeding 20dB ensures minimal signal reflection. These specifications maintain ANSI/TIA/EIA-455-171-A-2001 compliance, guaranteeing compatibility with standard fiber optic test equipment and industry practices. **Connector Configuration** The cable features duplex SC/UPC to ST/UPC connectors configured in Type A to B crossover arrangement—the most common standard for interconnecting diverse fiber equipment. The precision-polished UPC (Ultra Physical Contact) connectors provide exceptional return loss performance and durability across thousands of connection cycles. **Installation & Compliance** The 1.8mm outside diameter with riser-rated (OFNR) jacketing enables flexible routing through cable trays, conduit, and building infrastructure while meeting fire-safety ratings for non-plenum applications. TAA compliance ensures suitability for government procurement, and RoHS/ELV certification demonstrates environmental responsibility and regulatory adherence. **Applications** Ideal for connecting single-mode fiber optic equipment including DWDM systems, long-distance telecommunications links, carrier-class networking equipment, and enterprise data center interconnects. The 8-meter length accommodates moderate equipment separation with minimal signal loss. **Quality Assurance** Available in custom lengths for specific deployment requirements, with 90-day limited warranty coverage. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Standard quantity packaging accommodates network installations while maintaining cost efficiency. Industry-tested and certified for reliable performance in demanding professional environments.
