The JBX42200 45-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. This comprehensive product combines superior optical performance with regulatory compliance, making it an ideal choice for telecommunications providers, data center operators, and enterprise IT departments. Optical Performance and Specifications: Built with G.657.A1 glass fiber and a 9/125 micron core, this cable delivers exceptional transmission characteristics. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal attenuation, while the return loss of ≥20dB maintains signal integrity across critical network links. Attenuation measurements comply with industry standards, testing at 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, supporting both traditional and long-wavelength applications. Connector Configuration: The LC/APC to FC/UPC configuration provides a duplex Type A to B crossover connection—the industry standard for most duplex patch cord applications. LC connectors offer compact form factors ideal for high-density environments, while FC connectors provide secure threaded connections suitable for industrial and demanding installations. Compliance and Safety: Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets government procurement requirements and environmental standards. The riser-rated (OFNR) jacketing ensures fire safety compliance in commercial building installations. All components are manufactured across trusted facilities in Taiwan, the United States, and China. Practical Advantages: • 45-meter length eliminates the need for multiple shorter cables • Yellow jacketing provides visual identification in patch panels • 1.8mm diameter facilitates easy routing and management • Custom length availability for specialized requirements • 90-day limited warranty provides buyer confidence Applications: Ideally suited for telecommunications networks, fiber-to-the-premises (FTTP) installations, data center interconnects, and enterprise backbone networks. The singlemode specification supports both short and long-distance transmission requirements.
