The JBX88291 9-meter ST/ST Duplex Singlemode Fiber Patch Cable represents the intersection of performance, compliance, and value in modern fiber optic infrastructure. Built to exacting telecommunications standards, this cable serves as the backbone connection solution for organizations prioritizing signal quality and regulatory adherence. **Technical Excellence:** This duplex singlemode fiber patch cable features a precision-engineered 9/125 micron core with G.657.A1 glass fiber, optimized for long-distance, low-loss signal transmission. With attenuation specifications of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, it performs flawlessly across the entire telecommunications spectrum. The insertion loss rating of ≤0.35dB (typical 0.15dB) and return loss ≥20dB ensure minimal signal degradation, critical for maintaining network performance and reducing overall system costs through improved signal-to-noise ratios. **Professional-Grade Construction:** The cable's riser-rated (OFNR) green jacket provides flame-resistance and durability for both indoor and mixed-use installations. Its compact 1.8mm outer diameter facilitates easier cable management and routing through tight spaces, while the duplex configuration enables bidirectional communication through a single cable assembly. ST/UPC connectors with Type A to B crossover polarity—the industry standard for duplex communications—ensure plug-and-play compatibility with existing infrastructure. **Compliance & Reliability:** Fully TAA-compliant and manufactured with RoHS/ELV certification, this cable meets stringent federal procurement requirements and environmental standards. Manufactured in Taiwan, the US, and China, with strategic distribution centers in Danville CA, Fort Worth TX, and Beaufort SC, availability is assured with free standard shipping on orders exceeding $99. **Ideal Applications:** Perfect for telecommunications networks, ISP backbone installations, data centers, enterprise campus connectivity, and any environment requiring single-mode fiber's superior distance and bandwidth capabilities. Its 90-day limited warranty provides peace of mind, while ANSI/TIA/EIA-455-171-A compliance testing validates performance under real-world conditions. **Customization Available:** While the standard 9-meter length addresses most common installations, custom lengths are available to match your specific deployment requirements, eliminating unnecessary cable waste and simplifying inventory management.
