The JBX43290 45-meter LC/APC to ST/APC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Manufactured to exacting standards with origins in Taiwan, the United States, and China, this cable combines exceptional optical performance with enterprise-grade reliability. **Technical Excellence** This singlemode fiber cable utilizes 9/125 core/cladding geometry with G.657.A1 glass fiber composition, delivering optimal performance across telecommunications wavelengths. Measured insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while return loss ≥20dB protects against harmful signal reflections. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm are independently verified according to ANSI/TIA/EIA-455-171-A-2001 standards. **Durability and Compliance** The 1.8mm diameter yellow jacket features OFNR (riser-rated) construction, enabling safe installation in vertical cable runs within building plenum spaces. RoHS and ELV directive compliance meets stringent environmental regulations, making it suitable for government, healthcare, and regulated industry applications. TAA compliance certifies procurement eligibility for federal and institutional buyers. **Practical Advantages** The simplex configuration with LC/APC and ST/APC connectors provides optimal compatibility with diverse network infrastructure. Straight-through polarity ensures seamless integration into existing installations. The generous 45-meter length accommodates extended runs while minimizing splice points and potential failure modes. Yellow jacket coloring aids visual identification within complex cable management systems. **Customization and Support** Custom lengths are available for unique installation requirements. The cable ships from three US distribution centers (Danville, CA; Fort Worth, TX; and Beaufort, SC), enabling rapid deployment. Comprehensive 90-day limited warranty coverage and free standard shipping on orders over $99 enhance overall value proposition. **Applications** Ideal for telecommunications equipment connections, data center backbone infrastructure, long-distance signal transmission, and enterprise network upgrades where signal integrity and reliability are non-negotiable.
