The JBX42314 SC/APC to FC/UPC duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring reliable fiber optic connectivity. This 15-meter cable is engineered for single-mode transmission applications, delivering superior performance in long-distance, high-bandwidth network environments. **Technical Excellence** Constructed with 9/125 singlemode fiber and G.657.A1 glass fiber, this cable provides optimal signal fidelity with minimal attenuation. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB exceed industry standards, ensuring clean signal transmission at both 1310nm and 1550nm wavelengths. Each cable is individually tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards before shipment. **Connector Configuration** The SC/APC (Angled Physical Contact) to FC/UPC (Ultra Polished Connector) configuration with Type A to B crossover polarity addresses the most common duplex patch cord requirements. This combination accommodates diverse network architectures while maintaining signal integrity across connection points. **Compliance and Certifications** Fully TAA (Trade Agreements Act) compliant, this cable meets procurement requirements for government and institutional buyers. RoHS and ELV directive compliance ensures environmental responsibility without compromising performance. The OFNR (Optical Fiber Non-conductive Riser) jacketing rating provides safe installation in vertical building applications. **Installation and Identification** The distinctive yellow jacket simplifies cable management and reduces identification errors in complex installations. The 1.8mm outer diameter ensures compatibility with standard patch panel layouts. Custom lengths are available for specialized applications. **Support and Reliability** Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Includes 90-day limited warranty and free standard shipping on orders exceeding $99. Ideal for telecommunications facilities, data centers, and enterprise network infrastructure requiring proven, standards-compliant fiber connectivity solutions.
