The JBX86193 SC/ST Duplex Singlemode Fiber Patch Cable represents a premium solution for professional fiber optic network deployments. This 12-meter cable is specifically engineered for environments demanding high-speed, long-distance data transmission with minimal signal degradation. **Technical Excellence** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers performance specifications that exceed industry standards. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure signal fidelity across both 1310nm and 1550nm wavelengths. These specifications comply with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing compatibility with carrier-grade telecommunications equipment. **Compliance and Safety** TAA compliance makes this cable suitable for government, enterprise, and institutional procurement processes. RoHS/ELV certification ensures environmentally responsible manufacturing. The riser-rated (OFNR) jacketing with 1.8mm diameter provides fire safety compliance for in-building installations while maintaining flexibility for routing through cable management systems. **Connector Configuration** The SC/UPC to ST/UPC connector pairing with Type A to B crossover polarity represents the most common duplex patch cord configuration, ensuring seamless integration with existing network infrastructure without requiring additional adapters. **Applications** Ideal for telecommunications backbone networks, data center interconnects, campus network installations, and any application requiring reliable singlemode fiber transmission. The duplex configuration enables simultaneous bidirectional communication. **Quality and Support** Manufactured to rigorous standards with quality testing at multiple production facilities, backed by a 90-day limited warranty. Custom lengths available for specialized installations. Free standard shipping on orders exceeding $99, with rapid fulfillment from multiple U.S. distribution centers.
