The JBX43620 FC/APC to ST/UPC simplex singlemode fiber patch cable represents a premium connectivity solution for telecommunications professionals, data centers, and network infrastructure specialists. At 45 meters, this cable bridges significant distances while maintaining signal integrity and minimizing attenuation losses. **Technical Excellence:** Constructed with 9/125 micron singlemode fiber core and G.657.A1 grade glass, this cable delivers outstanding optical performance. Insertion loss measures ≤0.35dB (0.15dB typical), with return loss rated at ≥20dB, ensuring minimal signal degradation. Attenuation specs of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm provide predictable performance across telecommunications wavelengths. **Professional-Grade Construction:** The yellow OFNR-rated jacket provides riser-rated fire safety compliance suitable for vertical cable runs in commercial buildings. The 1.8mm outer diameter accommodates standard cable management systems while the straight-through polarity ensures correct signal direction. FC/APC connectors deliver low-loss connections, while ST/UPC termination provides broad compatibility with existing infrastructure. **Compliance & Standards:** TAA compliant for government procurement, RoHS/ELV directive compliant for environmental standards. Manufactured to ANSI/TIA/EIA-455-171-A attenuation testing standards, guaranteeing consistent quality and performance. **Practical Benefits:** - Free standard shipping on orders over $99 - Custom lengths available for specific requirements - 90-day limited warranty - Ships from multiple U.S. warehouses (California, Texas, South Carolina) - Suitable for telecommunications, data centers, and network backbone applications **Care & Compatibility:** Handle connectors with care to maintain low insertion loss. Compatible with FC/APC and ST/UPC equipped network equipment. Store in protective cases when not deployed. Ideal for both temporary testing and permanent installations in indoor environments.
