The JBX43485 ST/APC to ST/UPC fiber patch cable represents professional-quality optical connectivity for demanding network environments. This 3-meter simplex configuration delivers single-strand transmission capabilities ideal for point-to-point fiber connections in telecommunications facilities, data centers, and enterprise networks. Key Technical Specifications: The cable features a robust 9/125 micrometer singlemode core constructed from G.657.A1 glass fiber, supporting both 1310nm and 1550nm wavelengths with exceptional performance characteristics. Attenuation measurements meet or exceed industry standards at 0.25 dB/km (1310nm) and 0.35 dB/km (1550nm). The cable's 1.8mm outer diameter and OFNR riser rating ensure compatibility with standard conduit systems and building infrastructure while maintaining fire safety compliance. Connector Performance: The ST/APC (straight physical contact with angled polish) to ST/UPC (ultra-physical contact with standard polish) configuration addresses mixed-environment connectivity scenarios. The APC connector side provides superior return loss performance with its angled ferrule design, while the UPC termination accommodates standard network equipment. Measured insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss specifications of ≥20dB prevent reflective noise and signal integrity issues. Compliance and Quality Assurance: TAA compliance certification ensures this cable meets Buy American Act requirements for government and institutional procurement. RoHS and ELV directive adherence confirms lead-free construction and environmental responsibility. All cables undergo rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance across manufacturing batches. Applications and Use Cases: Ideal for upgrading existing fiber infrastructure, disaster recovery site connections, and mixed-environment network deployments. The yellow jacket provides high-visibility identification in complex cable management systems. Available in custom lengths for specialized installations, with convenient free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty for customer confidence.
