The JBX86195 20m SC/ST Duplex Singlemode Fiber Patch Cable represents the gold standard in optical connectivity solutions for modern data transmission infrastructure. This precision-engineered cable combines telecommunications-grade quality with government compliance certifications, making it the preferred choice for federal, enterprise, and carrier-class deployments. **Superior Optical Performance** Built with a 9/125 micron singlemode core and premium G.657.A1 glass fiber, this cable minimizes signal degradation over long distances. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure clean, reliable signal transmission across both 1310nm and 1550nm wavelengths. Comprehensive attenuation testing per ANSI/TIA/EIA-455-171-A standards guarantees consistent performance across your network infrastructure. **Compliance & Reliability** As a TAA-compliant product, this cable meets Buy American Act requirements, making it eligible for federal procurement contracts. Full RoHS and ELV directive compliance ensures environmental responsibility without compromising performance. The 90-day limited warranty provides additional peace of mind for your investment. **Versatile Duplex Configuration** The duplex design with Type A to B crossover polarity (the most common configuration) supports simultaneous bidirectional communication, eliminating the need for separate cables. This reduces cable clutter, simplifies management, and lowers total cost of ownership in complex network environments. **Installation & Safety** With an ultra-compact 1.8mm outer diameter, this cable navigates tight cable pathways, conduit systems, and overhead trays with ease. The OFNR riser-rated jacketing provides essential fire safety protection in plenum spaces and vertical cable runs, meeting building codes across commercial, industrial, and institutional settings. **Practical Advantages** Available in custom lengths for unique network requirements, the JBX86195 scales from small office installations to large-scale data center deployments. Free standard shipping on orders exceeding $99, with fulfillment from strategically located distribution centers in California, Texas, and South Carolina ensures rapid delivery. **Ideal Applications** Perfect for telecommunications hubs, enterprise campus networks, data center interconnects, research institutions, and any environment demanding single-mode optical performance with government compliance credentials.
