The JBX88269 40-meter ST/ST Duplex Singlemode Fiber Patch Cable represents a reliable solution for enterprise-grade network infrastructure. Engineered for telecommunications, data centers, and mission-critical connectivity, this cable combines precision manufacturing with proven performance standards. Specifications and Performance: This duplex fiber patch cable features a 9/125 singlemode core construction, ideal for long-distance, high-bandwidth signal transmission. The G.657.A1 glass fiber specification ensures optimal signal propagation with minimal signal degradation. With insertion loss of ≤0.35dB typical (maximum 0.15dB at standard wavelengths), this cable delivers superior performance compared to standard alternatives. The return loss specification of ≥20dB guarantees excellent signal reflection performance, critical for maintaining signal quality over extended distances. Technical Advantages: The ST/UPC connectors provide reliable optical connections with consistent performance. Type A to B crossover polarity configuration is the industry standard for duplex patch cords, ensuring compatibility with existing network infrastructure. The 1.8mm jacket diameter offers a balance between flexibility and durability, facilitating installation in tight spaces while maintaining structural integrity. Compliance and Standards: Fully TAA compliant for federal procurement requirements, this cable meets government sourcing guidelines. RoHS/ELV certification confirms environmental responsibility and regulatory compliance. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing measurement accuracy and reliability. Installation and Applications: Ideal for connecting network switches, routers, and fiber optic equipment in data centers, telecom facilities, and enterprise networks. The riser-rated (OFNR) jacketing makes it suitable for in-building backbone installations. Available in custom lengths to meet specific deployment requirements. Warranty and Support: 90-day limited warranty provides peace of mind on your investment. Free standard shipping on orders exceeding $99, with multiple warehouse locations ensuring rapid delivery.
