The JBX85068 3m LC/ST Duplex 9/125 Singlemode Fiber Patch Cable is a professional-grade solution designed for mission-critical fiber optic connectivity. Built to exacting telecommunications standards, this cable delivers the performance and reliability required in modern network infrastructure. **Technical Excellence** This singlemode fiber patch cable features 9/125 core/cladding dimensions with G.657.A1 specifications, supporting both 1310nm and 1550nm wavelengths commonly used in telecommunications. The cable achieves exceptional attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, ensuring minimal signal loss over longer distances. Low insertion loss (≤0.35dB typical) and high return loss (≥20dB) specifications guarantee clean signal transmission for high-speed data applications. **Superior Connectivity** LC/ST connectors provide excellent compatibility with standard telecommunications equipment. The Type A to B crossover polarity configuration is the industry standard for duplex patch cords, simplifying installation and reducing configuration errors. Precision connector alignment ensures consistent performance and longevity. **Build Quality & Safety** The yellow OFNR riser-rated jacket provides flame resistance and safety in building installations while the 1.8mm outside diameter allows easy routing through tight conduit spaces. RoHS compliance and EU directive adherence make this cable suitable for environmentally conscious installations. Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards. **Applications** Ideal for data centers, telecommunications facilities, enterprise networks, fiber-to-the-desk installations, and backbone network connections. The 3-meter length accommodates typical equipment spacing while remaining cost-effective. **Shipping & Support** Qualifies for free standard shipping on orders over $99. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Backed by a 90-day limited warranty. Custom lengths available for specialized requirements.
