The JBX88351 9-meter ST/ST duplex singlemode fiber patch cable represents professional-grade connectivity for demanding network environments. Built to exacting specifications, this cable combines performance, compliance, and reliability in a single solution. **Technical Performance** Designed around a 9/125 singlemode core with G.657.A1 glass fiber, this cable achieves exceptional optical performance. The typical insertion loss of just 0.15dB (maximum 0.35dB) minimizes signal degradation over the 9-meter span, while return loss exceeding 20dB ensures minimal signal reflection. Performance is rigorously tested at both 1310nm and 1550nm wavelengths according to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistency across the telecommunications spectrum. **Build Quality & Compliance** The OFNR riser-rated PVC jacketing with 1.8mm outside diameter provides optimal flexibility for installation while meeting building codes and safety standards. As a TAA-compliant product meeting RoHS/ELV requirements, this cable satisfies federal procurement standards and environmental directives, making it ideal for government and enterprise deployments. **Duplex Configuration** The cable features Type A-to-B crossover polarity, the industry standard for duplex patch cords, enabling seamless integration with existing telecommunications infrastructure. ST/UPC connectors ensure reliable mechanical connections with minimal back-reflection. **Practical Applications** Ideal for data center backbone connectivity, campus area networks, long-distance telecommunications, and any application requiring single-mode fiber's superior bandwidth and range. The 9-meter length accommodates typical rack-to-switch distances while minimizing excess cable management issues. **Flexibility & Support** Available in custom lengths to suit specific installation requirements, backed by a 90-day limited warranty. Free standard shipping applies to orders exceeding $99, with inventory stocked in multiple U.S. locations for rapid fulfillment.
