The JBX43464 15m FC/APC to FC/APC Simplex Singlemode Fiber Patch Cable represents a reliable solution for mission-critical fiber optic networking applications. This professional-grade cable combines precision engineering with compliance certifications required by government and enterprise procurement standards. **Technical Specifications:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber technology, this cable delivers superior performance characteristics. The exceptionally low insertion loss of ≤0.35dB (0.15dB typical) minimizes signal degradation, while return loss exceeding 20dB ensures minimal signal reflection. Pre-tested to ANSI/TIA/EIA-455-171-A-2001 standards, this cable maintains attenuation performance of 0.25 dB/km at 1310nm wavelength or 0.35 dB/km at 1550nm, making it suitable for both traditional and long-wavelength transmission systems. **Build Quality & Safety:** The OFNR (Optical Fiber Non-Conductive Riser) jacket rating ensures fire safety compliance in vertical cable runs within commercial buildings. RoHS and ELV directive compliance makes this cable environmentally responsible and meeting stringent EU standards. The 1.8mm outer diameter provides durability while maintaining flexibility for routing through tight spaces. **Design Features:** Bright yellow jacket coding facilitates rapid cable identification in densely populated patch panel environments. Straight-through polarity ensures straightforward termination and minimal installation errors. FC/APC connectors provide enhanced performance characteristics compared to FC/PC alternatives, with superior return loss for reducing back-reflection. **Flexibility & Customization:** While this listing features the popular 15-meter length, custom lengths are available to match your specific network infrastructure requirements. This flexibility eliminates excess cable clutter and associated costs. **Applications:** Ideal for telecommunications facilities, data centers, research laboratories, and any environment requiring high-fidelity singlemode signal transmission. Commonly deployed for connecting optical testing equipment, telecommunications systems, and fiber-optic sensor networks. **Warranty & Support:** Backed by a 90-day limited warranty providing peace of mind.
