The JBX85210 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical network applications. Manufactured to exacting standards, this 80-meter cable combines precision engineering with practical design elements that network professionals demand. TECHNICAL EXCELLENCE: Built with G.657.A1 glass fiber and a 9/125 singlemode core, this patch cable supports long-distance signal transmission with superior optical performance. The cable achieves insertion loss of just ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring minimal signal degradation across extended runs. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm comply with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance in carrier-grade applications. PRACTICAL DESIGN: The bright yellow outer jacket (1.8mm diameter) provides excellent visibility in cable-dense environments, reducing installation errors and simplifying maintenance. Type A to B crossover polarity configuration eliminates the need for specialized connectors in most duplex applications. OFNR riser-rated jacketing permits vertical installation in building plenum spaces, while the durable plastic accessories ensure longevity in harsh network environments. COMPLIANCE & CERTIFICATION: TAA compliant and RoHS/ELV certified, this cable meets U.S. government procurement requirements and environmental regulations. Manufacturing facilities in Taiwan, the United States, and China ensure quality consistency and supply reliability. APPLICATIONS: Ideal for telecommunications networks, data center connectivity, backbone infrastructure, WAN links, and long-distance campus networks. The 80-meter length eliminates the need for multiple shorter cables in extended runs. CUSTOMIZATION & SUPPORT: Custom lengths available to match your specific installation requirements. Each cable includes a 90-day limited warranty. Orders over $99 qualify for free standard shipping from multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC).
