The JBX93201 50m SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for demanding fiber optic network applications. Built with precision engineering and premium materials, this cable delivers the performance, reliability, and compliance required by modern telecommunications and data center infrastructures. **Technical Excellence:** Features a 9/125 singlemode core with G.657.A1 glass fiber, specifically designed for long-distance, high-bandwidth signal transmission. The cable achieves exceptional attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, with insertion loss testing performed in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Typical insertion loss is just 0.15dB, with maximum of 0.35dB, and return loss exceeds 20dB for superior signal quality. **Durability and Safety:** Constructed with OFNR-rated (Riser Rated) jacketing that meets fire safety codes and is suitable for vertical runs between floors in commercial buildings. The 1.8mm outside diameter provides a compact profile for efficient cable management without compromising durability. **Compliance and Standards:** TAA compliant for government and federal procurement requirements. RoHS/ELV certified (EU directive 2002/95/EC), ensuring environmental responsibility and regulatory compliance across global markets. **Connectivity:** Factory-terminated SC/UPC to ST/UPC connectors with Type A to B crossover polarity configuration—the most common and reliable duplex patch cord setup. This standard polarity ensures seamless integration with existing network infrastructure. **Practical Advantages:** The 50-meter length provides flexibility for building-scale networking needs without requiring splices or additional connections. Available in custom lengths to meet specific installation requirements. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. **Applications:** Ideal for telecommunications networks, data center patch panels, campus area networks (CANs), and enterprise IT infrastructure requiring reliable singlemode fiber connectivity. The balanced performance and compliance features make this cable suitable for mission-critical applications. **Support and Warranty:** Backed by a comprehensive 90-day limited warranty, providing peace of mind for your network investment. Made with quality materials from trusted manufacturing locations (Taiwan, US, China), this cable delivers consistent performance and longevity.
