The JBX43571 ST/APC to FC/APC Simplex Singlemode Fiber Patch Cable represents a professional-grade solution for connecting fiber optic equipment in telecommunications networks, data centers, and enterprise infrastructure. This 1-meter cable combines precision engineering with compliance certifications required for government and enterprise procurement. **Technical Excellence**: Featuring 9/125 singlemode fiber construction with G.657.A1 glass fiber, this cable delivers exceptional performance characteristics. The insertion loss specification of ≤0.35dB at 1550nm and measured attenuation of 0.35dB/km ensures minimal signal loss over distance. Return loss of ≥20dB provides superior signal reflection performance, critical for high-speed data transmission. All measurements are performed in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance & Certification**: TAA compliance makes this cable eligible for government contracts and procurement processes. RoHS and ELV directive compliance ensures environmental responsibility and reduces hazardous materials. The OFNR (Optical Fiber Non-Conductive Riser) jacket rating meets building code requirements for in-wall installations above ground floor levels. **Practical Design Features**: The bright yellow jacket provides instant visual identification in complex multi-cable environments, reducing installation errors and simplifying troubleshooting. The 1.8mm outside diameter balances durability with manageable cable routing. ST/APC and FC/APC connectors are industry standards, ensuring compatibility with existing infrastructure. **Flexibility & Support**: Custom lengths are available to match your specific installation requirements, minimizing waste and reducing overall project costs. The 90-day limited warranty provides confidence in product quality, while free standard shipping on orders over $99 improves cost efficiency. **Applications**: Ideal for telecommunications facilities, data center backbone connections, CATV systems, and any single-strand fiber signal transmission requirement where singlemode performance is essential. The cable performs reliably in both 1310nm and 1550nm operating windows. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery.
