The JBX88329 represents enterprise-class fiber optic connectivity, delivering reliable signal transmission over 40 meters of duplex singlemode fiber. Designed for data centers, telecommunications infrastructure, and high-speed networking applications, this patch cable meets the demanding requirements of modern IT environments. Optical Performance Excellence: Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable achieves exceptional attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. The low insertion loss specification (≤0.35dB typical 0.15dB) minimizes signal degradation, while the ≥20dB return loss ensures minimal reflection interference. These performance metrics have been rigorously tested in accordance with ANSI/TIA/EIA-455-171-A standards, guaranteeing consistency and reliability. Connector Technology: The ST/UPC connectors feature Type A to B crossover polarity, the industry standard for duplex patch cord applications. This configuration ensures proper signal routing and seamless integration with existing fiber infrastructure. The precision-polished connectors maintain alignment tolerances critical for singlemode transmission. Building Compliance & Safety: OFNR (Optical Fiber Non-Conductive Riser) rated jacketing meets stringent building code requirements, making this cable suitable for in-wall installations in commercial and industrial settings. TAA compliance satisfies government procurement regulations, while RoHS and ELV directives ensure environmental responsibility and hazardous substance restrictions. Practical Advantages: The compact 1.8mm outside diameter facilitates efficient cable management in crowded equipment racks and conduit systems. Free standard shipping on orders exceeding $99 reduces acquisition costs. Multiple fulfillment centers (Danville CA, Fort Worth TX, Beaufort SC) enable rapid delivery. Custom length options accommodate specific deployment requirements beyond the standard 40m configuration. Industry Applications: Ideal for long-distance campus networks, data center backbone connections, telecommunications installations, and research facilities requiring low-loss, high-bandwidth optical transmission. The 40-meter length bridges medium-distance requirements efficiently, while the duplex configuration supports bidirectional communication on a single cable assembly. Warranty & Support: 90-day limited warranty provides confidence in product quality and performance consistency. Manufactured in Taiwan, United States, and China with stringent quality controls.
