The JBX43585 is a precision-engineered fiber optic patch cable designed for mission-critical network applications requiring exceptional signal fidelity and regulatory compliance. This 20-meter simplex cable seamlessly connects ST/APC and FC/APC connectors, providing reliable signal transmission in telecommunications infrastructure, data centers, and enterprise network environments. Technical Specifications: The cable utilizes 9/125 singlemode fiber core with G.657.A1 specification, offering superior bend performance compared to standard G.652 fiber. Measured insertion loss remains extremely low at ≤0.35dB (typical 0.15dB), with return loss exceeding 20dB, ensuring minimal signal degradation and reflection. The cable has been attenuation-tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm and 1550nm wavelengths (0.25 dB/km and 0.35 dB/km respectively). Construction & Durability: The 1.8mm outer diameter yellow jacket is OFNR riser-rated, providing fire-resistance suitable for plenum and non-plenum installations. This distinctive yellow coloring facilitates cable identification in complex network layouts. The simplex design features a single fiber strand optimized for directional signal transmission. Compliance & Standards: Fully TAA-compliant for government and enterprise procurement requirements. RoHS and ELV directive compliant (EU directive 2002/95/EC). The cable meets international telecommunications standards and has been subjected to rigorous quality testing. Applications: Ideal for connecting telecommunications equipment, optical transceivers, network switches, and monitoring systems. Suitable for equipment interconnections, backbone runs, and patch panel configurations. Commonly deployed in carrier-grade installations, enterprise data centers, and compliance-sensitive environments. Value Added: Available in custom lengths for specialized installations. Backed by 90-day limited warranty. Free standard shipping on orders exceeding $99. Ships from multiple U.S. distribution centers (California, Texas, South Carolina) for expedited delivery. The cable's proven performance specifications and compliance certifications make it the preferred choice for network professionals requiring reliability and regulatory adherence.
