The JBX42592 fiber patch cable represents a premium solution for telecommunications and data center applications requiring high-performance singlemode connectivity. Spanning 55 meters, this duplex cable seamlessly bridges ST/APC and FC/APC connectors in a Type A to B crossover configuration—the industry standard for most duplex patch cord applications. Technical Excellence: Built with 9/125 G.657.A1 glass fiber, this cable exceeds modern network demands. The attenuation specification of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures minimal signal loss across both common wavelengths. With insertion loss ≤0.35dB and return loss ≥20dB, the cable maintains signal integrity for long-distance transmissions. All performance metrics are validated against ANSI/TIA/EIA-455-171-A-2001 standards. Practical Design Features: The 1.8mm outer diameter accommodates tight routing scenarios while the riser-rated OFNR jacketing ensures compliance with building codes and fire safety requirements. The vibrant yellow jacket aids in rapid identification and organized cable management, reducing installation time and maintenance errors. Compliance and Reliability: TAA compliance makes this cable suitable for U.S. government projects and GSA Schedule procurement. RoHS/ELV certification ensures environmental responsibility, while the 90-day limited warranty provides peace of mind. Manufactured in Taiwan, the US, or China with consistent quality control. Customization Available: Beyond the standard 55m length, custom lengths are available to match your specific installation requirements, minimizing waste and optimizing performance. Free standard shipping on orders over $99 adds value to bulk purchases. Ideal Applications: Network backbone connections, enterprise data centers, telecom facilities, and campus area networks where reliable, low-loss signal transmission is critical.
