The JBX88247 80-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for telecommunications, data center, and enterprise network environments requiring high-speed, long-distance fiber optic connectivity. **Technical Excellence:** Built with a 9/125 micron singlemode fiber core compliant with G.657.A1 specifications, this cable delivers superior performance across multiple wavelengths. The fiber achieves attenuation rates of just 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, with typical insertion loss of only 0.15dB and guaranteed maximum of 0.35dB. Return loss exceeds 20dB, ensuring minimal signal reflection and optimal data integrity. **Connectivity and Compatibility:** The ST/UPC to ST/UPC connector configuration with Type A to B crossover polarity provides standard duplex patch cord functionality. This widely-adopted connection type integrates seamlessly with existing infrastructure, making it ideal for upgrades and expansions. **Compliance and Safety:** Fully TAA compliant, this cable meets stringent government procurement requirements. RoHS and ELV compliant, it adheres to EU Directive 2002/95/EC environmental standards. The OFNR (Optical Fiber Non-Conductive Riser) rating enables safe installation in vertical cable runs and building spaces. **Practical Features:** The vibrant red jacket simplifies cable identification and management in crowded patch panels. At just 1.8mm outer diameter, it minimizes space requirements while maintaining durability through plastic accessory construction. The 80-meter length accommodates extensive horizontal runs between equipment racks or across facility distances. **Customization and Support:** Custom length options allow perfect fit for unique installations. Manufactured in Taiwan, the US, and China with redundant sourcing, this cable ships free on orders over $99 from multiple US distribution centers. The 90-day limited warranty provides peace of mind for your network investment. **Applications:** Perfect for data centers, telecommunications facilities, enterprise networks, research institutions, and mission-critical installations requiring reliable, standards-compliant fiber connectivity over extended distances.
