The JBX43286 is a professional-grade 25-meter LC/APC to ST/APC simplex singlemode fiber patch cable designed for critical network infrastructure applications. With its 9/125 singlemode fiber core and G.657.A1 glass specifications, this cable delivers exceptional signal fidelity and minimal signal degradation across extended distances. **Key Technical Features:** This simplex configuration transmits data in a single direction, making it ideal for dedicated point-to-point connections. The cable achieves insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, ensuring minimal signal loss and reflection. Performance is consistent across standard operating wavelengths, with attenuation of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. **Construction & Durability:** The 1.8mm outside diameter provides a compact profile for dense cable management, while the OFNR (Optical Fiber, Non-Conductive, Riser) rating ensures safe installation in plenum and riser spaces. The bright yellow jacket improves visibility during installation and maintenance. **Compliance & Standards:** TAA-compliant and manufactured to meet RoHS/ELV directives, this cable satisfies government procurement requirements. Rigorous testing per ANSI/TIA/EIA-455-171-A standards guarantees performance reliability. **Flexibility & Support:** Beyond the standard 25-meter length, custom lengths are available to match your exact installation requirements. With a 90-day limited warranty and rapid shipping from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC), you get dependable service and convenience. **Applications:** Perfect for data centers, telecommunications, audio/visual installations, and enterprise network upgrades where singlemode fiber's superior distance and speed capabilities are essential.
