The JBX42479 100-Meter FC/APC to FC/APC Duplex Singlemode Fiber Patch Cable represents a premium solution for professional fiber optic network installations. Designed to meet the exacting requirements of telecommunications, data centers, and broadcast facilities, this cable delivers exceptional performance in long-distance signal transmission applications. Technical Excellence: Built with G.657.A1 glass fiber, this singlemode cable features a precise 9/125 micrometer core and 1.8mm overall diameter jacketing. The cable achieves exceptional insertion loss performance of ≤0.35dB with typical values of 0.15dB, while maintaining return loss ratings of ≥20dB, ensuring signal integrity across extended cable runs. Connector Performance: The FC/APC (Angled Physical Contact) connectors provide superior optical performance compared to standard FC/PC connectors, with reduced back-reflection characteristics essential for sensitive optical systems. The Type A to B crossover polarity configuration is optimized for duplex patch cord applications. Compliance and Safety: This cable meets critical compliance requirements including RoHS/ELV directives and EU directive 2002/95/EC, making it suitable for regulated environments. TAA compliance ensures eligibility for government contracts and procurement requirements. Practical Installation: The distinctive yellow outer jacket facilitates quick cable identification during installation and maintenance. At 100 meters, this cable eliminates the need for multiple shorter segments while maintaining performance standards. The OFNR (Riser-Rated) jacket rating ensures safe use in vertical cable runs within building infrastructure. Customization Available: While this product ships at 100 meters, custom lengths are available to match specific installation requirements, reducing waste and installation complexity. Applications: Ideal for enterprise networks, telecommunications infrastructure, data center interconnects, broadcast studios, and any application requiring reliable, long-distance singlemode fiber connectivity. Backed by comprehensive testing standards and a 90-day limited warranty, this cable represents a trusted choice for professionals demanding premium fiber optic performance.
