The JBX43240 LC/APC to ST/UPC singlemode fiber patch cable represents a robust solution for connecting fiber optic network components with precision and reliability. At 0.5 meters in length, this simplex cable is particularly suited for short-distance interconnects in server rooms, telecommunications closets, and equipment racks where space efficiency is critical. Technical Excellence: This cable features 9/125 micromode fiber construction with G.657.A1 glass specifications, delivering superior bending characteristics while maintaining exceptional optical performance. The 1.8mm outer diameter provides flexibility for tight routing scenarios. Insertion loss is measured at ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB, meeting stringent performance standards for backbone and distribution networks. Connector Quality: The LC/APC (Angled Physical Contact) connector on one end provides enhanced return loss performance critical for sensitive optical systems. The ST/UPC (Ultra Physical Contact) connector on the opposite end ensures compatibility with legacy installations and diverse network architectures. This configuration enables seamless integration between modern and established infrastructure. Compliance and Standards: TAA compliance makes this cable suitable for government and defense sector projects. RoHS/ELV certification ensures environmental responsibility, while OFNR fire rating provides safe operation in plenum and riser applications. Performance testing adheres to ANSI/TIA/EIA standards, with documented attenuation characteristics at 1310nm and 1550nm wavelengths. Practical Advantages: The distinctive yellow jacket simplifies cable identification and management in complex installations, reducing installation time and troubleshooting errors. Custom lengths are available for applications requiring different cable runs. Ships from multiple U.S. locations (California, Texas, South Carolina) enabling rapid delivery, with free standard shipping on qualifying orders. Applications and Use Cases: Ideal for telecom equipment interconnection, data center networking, fiber-to-the-premises installations, and laboratory testing environments. The 0.5m length suits equipment-to-equipment connections without excess cable management complexity. Perfect for upgrades requiring specific connector combinations while maintaining cost efficiency and performance standards.
