The JBX93195 SC/ST singlemode fiber patch cable represents enterprise-grade connectivity engineered for professionals who demand reliability and performance. This 20-meter duplex configuration is specifically designed for telecommunications networks, data centers, and mission-critical fiber optic applications. **Technical Excellence:** Built with G.657.A1 grade optical fiber, this cable delivers exceptional performance characteristics. The 9/125 core diameter is the industry standard for singlemode transmission, enabling long-distance communication with minimal signal degradation. Measured insertion loss of ≤0.35dB (typical 0.15dB) ensures maximum signal integrity, while return loss specification of ≥20dB minimizes reflections that could compromise data quality. **Superior Construction:** The duplex configuration features two parallel fiber strands, enabling simultaneous two-way communication over a single cable run. SC/UPC to ST/UPC connectors with Type A to B crossover polarity represent the most common configuration for duplex patch cords, ensuring compatibility with standard network infrastructure. The 1.8mm outer diameter provides excellent bend radius characteristics without compromising durability. **Compliance & Quality:** TAA (Trade Agreements Act) compliance makes this cable suitable for government and federal projects. RoHS/ELV directive compliance demonstrates environmental responsibility. Manufacturing locations in Taiwan, US, and China ensure consistent quality across production batches. Riser-rated OFNR jacketing provides critical fire safety protection in building installations. **Applications:** Ideal for connecting telecommunications equipment, network switches, and optical transmission systems. Commonly used in backbone connections, interconnects between network nodes, and high-speed data transmission scenarios. The 20-meter length accommodates most standard installation distances within facility constraints. **Custom Solutions:** While this product is available as specified, custom lengths are available for specialized applications, allowing flexibility for unique installation requirements. **Value & Support:** Enjoy free standard shipping on orders exceeding $99, with fulfillment from strategically located warehouses (Danville CA, Fort Worth TX, Beaufort SC). Each cable includes a 90-day limited warranty, backed by professional technical support. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing performance specifications. Choose JBX93195 for reliable, standards-compliant fiber optic connectivity that meets professional installation requirements.
