The JBX42587 30-meter ST/APC to FC/APC duplex singlemode fiber patch cable represents the ideal solution for telecommunications infrastructure, data centers, and enterprise network environments requiring precision optical connectivity. This duplex cable configuration features matched ST/APC and FC/APC connectors with Type A to B crossover polarity—the industry standard for duplex patch cord applications—enabling seamless integration into existing fiber networks. Optical Performance Excellence: This singlemode fiber cable demonstrates exceptional optical characteristics tested and certified to ANSI/TIA/EIA-455-171-A standards. With insertion loss of merely 0.15dB typical (maximum 0.35dB) and return loss exceeding 20dB, the cable maintains signal integrity across long-distance transmissions. The 9/125 micron core specification combined with G.657.A1 glass fiber technology ensures compatibility with modern optical systems while supporting bend-insensitive performance. Robust Construction & Compliance: The cable features a protective 1.8mm outer diameter yellow jacket rated for riser environments (OFNR rating), providing both durability and installation visibility. TAA compliance and RoHS/ELV directive adherence make this cable suitable for government and regulated enterprise deployments. Available from multiple U.S. and international distribution points with rapid shipping. Applications & Benefits: Ideal for telecommunications networks, DWDM systems, metropolitan area networks (MANs), and fiber-to-the-premises (FTTP) installations. The 30-meter length bridges significant distances between optical equipment without signal degradation. Custom lengths are available for specialized installation requirements. Warranty & Support: Included 90-day limited warranty demonstrates manufacturer confidence. Free standard shipping on orders exceeding $99. Backed by optical industry compliance standards and quality construction from established manufacturing facilities in Taiwan, the United States, and China. Insertion Loss Specifications: 1310nm: 0.25dB/km; 1550nm: 0.35dB/km maximum. Perfect for long-haul fiber applications, backbone connectivity, or enterprise-class network installations.
