The JBX88241 ST/ST Duplex Singlemode Fiber Patch Cable represents the pinnacle of fiber optic connectivity solutions for telecommunications professionals and network installers. Spanning 50 meters of precision-engineered optical fiber, this cable delivers robust, high-bandwidth signal transmission for mission-critical applications. **Technical Excellence**: Built with 9/125 singlemode fiber core and G.657.A1 glass construction, this cable minimizes signal degradation across extended distances. The measured attenuation rate of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures superior performance for both traditional and long-haul applications. Insertion loss testing confirms ≤0.35dB (typical 0.15dB) with return loss ≥20dB, meeting ANSI/TIA/EIA-455-171-A-2001 standards. **Connector Specifications**: Featuring duplex ST/UPC connectors with Type A to B crossover polarity—the most common configuration for duplex patch cords—this cable integrates seamlessly into existing network infrastructures. The proven ST connector design offers reliable mating cycles and consistent performance. **Regulatory Compliance**: TAA compliant and RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets stringent government procurement standards and environmental regulations. Enterprise buyers and government contractors can deploy with confidence. **Installation-Ready**: The riser-rated (OFNR) 1.8mm jacketing provides fire-safety compliance for building installations. The vibrant red color aids in network documentation and cable management. Custom lengths available for specialized applications. **Value Proposition**: Backed by a 90-day limited warranty and available with free standard shipping on orders exceeding $99, this professional-grade solution offers exceptional reliability without premium pricing. Multiple domestic warehouses (California, Texas, South Carolina) ensure rapid deployment. Ideal for data centers, telecommunications facilities, campus networks, and enterprise backbone infrastructure requiring dependable singlemode connectivity.
