The JBX43434 15-meter FC/APC to FC/UPC simplex singlemode fiber patch cable represents a reliable solution for telecommunications professionals, data center operators, and network administrators seeking premium optical connectivity. This cable combines precision engineering with practical design to meet the rigorous demands of modern fiber optic installations. Key Technical Specifications: The cable features a 9/125 micrometer singlemode core, the industry standard for long-distance, high-bandwidth applications. The G.657.A1 glass fiber specification provides excellent attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Insertion loss testing confirms performance of ≤0.35dB with typical values around 0.15dB, while return loss exceeds 20dB—critical for minimizing signal reflection and maintaining system performance. Connector Configuration: The FC/APC (Angled Physical Contact) to FC/UPC (Ultra Physical Contact) configuration addresses the need for mixed connector environments commonly found in hybrid systems. FC connectors feature robust threading for secure connections in high-vibration or high-traffic areas, making them ideal for rack-mounted equipment and outdoor installations. Construction and Compliance: The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket meets stringent building safety codes and provides excellent abrasion resistance. At 1.8mm outer diameter, this cable facilitates easy routing through cable trays and conduit systems while maintaining the bend-resistant properties of G.657.A1 fiber. TAA compliance ensures suitability for government and enterprise contracts. RoHS/ELV certification confirms environmental responsibility. Applications and Use Cases: Ideal for telecommunications networks, data centers, laboratory environments, and long-distance signal transmission. The simplex design suits unidirectional applications where single-fiber transmission meets requirements. Custom length availability enables precise project specifications and reduces waste. Warranty and Support: Backed by a 90-day limited warranty with rapid shipping from multiple U.S. locations. Free standard shipping on orders exceeding $99 provides excellent value for bulk installations.
