The JBX86185 SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for demanding fiber optic networking environments. This 3-meter cable combines precision engineering with strict compliance standards to deliver reliable signal transmission in telecommunications, data center, and enterprise network applications. **Technical Specifications & Performance:** This duplex patch cable features a 9/125 micrometer singlemode core, the industry standard for long-distance telecommunications. The cable achieves exceptional signal integrity with insertion loss of ≤0.35dB at typical conditions (0.15dB) and return loss exceeding 20dB, ensuring minimal signal degradation over fiber runs. Attenuation is rated at 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, making it suitable for both conventional and extended wavelength applications. All measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Connector Configuration:** The SC/UPC to ST/UPC connector arrangement uses Type A to B crossover polarity, the most common configuration for duplex patch cord applications. This ensures straightforward installation and compatibility with standard network infrastructure. Both connector types feature UPC (Ultra Polished Connector) geometry for optimal performance. **Build Quality & Durability:** Constructed with G.657.A1 grade glass fiber and encased in 1.8mm diameter OFNR (Riser Rated) jacketing, this cable meets stringent fire safety codes required in commercial buildings and data centers. The plastic accessories and robust construction withstand typical installation stresses while maintaining performance integrity. **Compliance & Certifications:** TAA (Trade Agreements Act) compliant for government and institutional purchasing. Fully RoHS/ELV compliant per EU Directive 2002/95/EC, reflecting commitment to environmental standards. Manufactured with quality control from trusted facilities in Taiwan, US, and China. **Applications:** - Data center backbone connectivity - Telecom equipment interconnection - Campus network installations - Long-distance signal transmission - Wavelength-division multiplexing systems **Shipping & Support:** Available with free standard shipping on orders exceeding $99. Ships from strategically located warehouses (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Includes 90-day limited warranty. Custom lengths available for specialized requirements.
