The JBX43578 6-meter ST/APC to FC/APC simplex fiber patch cable represents professional-grade connectivity for critical fiber optic applications. Engineered with precision-aligned singlemode 9/125 core fiber, this cable delivers exceptional performance for long-distance, high-bandwidth signal transmission in telecommunications and data center environments. **Key Technical Specifications:** This simplex configuration features a single fiber strand optimized for unidirectional signal transmission. The 9/125 micrometer core design minimizes mode dispersion, ensuring signal fidelity across extended distances. Attenuation testing confirms performance at both primary wavelengths: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The angled physical contact (APC) connectors on both ends provide superior optical performance with return loss exceeding 20dB, significantly reducing back-reflection and signal degradation compared to standard connectors. **Build Quality & Compliance:** Constructed with OFNR (Optical Fiber, Non-conductive, Riser) rated jacket material, this cable meets strict building code requirements for vertical runs and plenum-adjacent installations. The 1.8mm outer diameter facilitates efficient cable management in tight spaces. RoHS/ELV compliant manufacturing ensures environmental responsibility, while TAA compliance makes it suitable for government and institutional procurement. **Applications & Benefits:** Ideal for telecommunications networks, data centers, fiber-to-the-premises (FTTP) installations, and enterprise backbone connectivity. The bright yellow jacket provides instant visual identification in complex multi-cable environments, reducing installation errors and maintenance time. **Quality Assurance:** Manufactured to exacting standards with insertion loss testing (≤0.35dB typical) and comprehensive attenuation verification per ANSI/TIA/EIA-455-171-A-2001. Available in custom lengths upon request for specific installation requirements. Backed by a 90-day limited warranty, with convenient shipping from US distribution centers.
