The JBX42328 SC/APC to FC/UPC duplex singlemode fiber patch cable represents a critical infrastructure component for modern telecommunications networks, data centers, and enterprise environments requiring uncompromising signal quality and reliability. Technical Excellence: This 85-meter cable features 9/125 singlemode fiber construction optimized for long-distance, high-bandwidth applications. The SC/APC (angled physical contact) to FC/UPC (ultra-polished) connector configuration provides the most common duplex patch cord polarity (Type A to B crossover), ensuring seamless compatibility with standard network equipment. Performance metrics include insertion loss ≤0.35dB with typical values of 0.15dB, and return loss ≥20dB, both tested to ANSI/TIA/EIA-455-171-A-2001 standards. Durable Construction: The 1.8mm diameter jacket utilizes OFNR (Optical Fiber Non-conductive Riser) rated material, providing superior fire resistance and chemical protection essential for plenum and riser installations. G.657.A1 glass fiber offers excellent macro-bend performance while maintaining compatibility with legacy G.652.D systems. Compliance & Certification: TAA compliant for U.S. government and defense applications, and fully RoHS/ELV compliant per EU directive 2002/95/EC, this cable meets the strictest environmental and procurement standards. Applications: Ideal for connecting network switches to patch panels, router interconnections, and backbone cabling in enterprise data centers. The 85-meter length accommodates extensive horizontal runs in large facilities while maintaining signal integrity. Customization & Support: Custom lengths are available for specialized installations. Manufactured in Taiwan, the U.S., or China, with fulfillment from multiple distribution centers ensuring rapid delivery. Includes 90-day limited warranty. Free standard shipping on orders over $99.
