The JBX88412 ST/ST singlemode fiber patch cable represents a reliable solution for telecommunications infrastructure requiring precision fiber optics. This 10-meter duplex cable combines professional-grade components with compliance certifications necessary for government and enterprise deployments. **Technical Specifications:** Built with 9/125 singlemode fiber and G.657.A1 glass composition, the cable delivers ultra-low attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss tests confirm ≤0.35dB performance (typical 0.15dB), while return loss maintains ≥20dB specifications. These measurements exceed industry standards for single-mode optical transmission, ensuring minimal signal degradation over longer network spans. **Key Features & Benefits:** - ST/UPC to ST/UPC connectors with Type A to B crossover configuration - Pink jacket for easy cable identification and inventory management - Duplex design enables bidirectional communication on single cable run - OFNR riser rating permits installation in plenum areas and building risers - TAA compliant for federal procurement and government contracts - RoHS/ELV certified environmental compliance - 90-day limited warranty with responsive technical support **Applications & Use Cases:** Ideal for connecting fiber optic equipment in data centers, telecommunications facilities, educational institutions, and government networks. The singlemode architecture supports long-distance transmission at high speeds, making it suitable for backbone connections, campus fiber networks, and inter-building links. The professional-grade 1.8mm diameter jacketing resists abrasion and environmental stress. **Quality Assurance:** Each cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards, with detailed performance metrics documented. Manufacturing locations in Taiwan, United States, and China ensure quality consistency. Ships free on orders exceeding $99 from multiple distribution centers nationwide. **Customization Available:** While the standard 10m length covers most applications, custom length options accommodate unique network architecture requirements.
