The JBX43628 FC/APC to ST/UPC singlemode fiber patch cable represents professional-grade connectivity for demanding telecommunications and data center applications. This 85-meter simplex cable combines premium component selection with rigorous quality testing to ensure optimal performance in critical network installations. Technical Excellence: Constructed with 9/125 singlemode fiber core and G.657.A1 specification glass fiber, this cable delivers superior signal integrity across standard telecommunications wavelengths. Independent attenuation testing confirms performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, with insertion loss measurements of ≤0.35dB typical (0.15dB). Return loss specifications exceed ≥20dB, meeting ANSI/TIA/EIA-455-171-A-2001 standards. Compliance and Certification: TAA compliant construction ensures eligibility for government contracts and GSA-approved procurement. RoHS/ELV directive compliance demonstrates environmental responsibility without compromising performance. The OFNR-rated yellow jacket provides fire safety certification for installation in building risers and plenum spaces. Practical Design Features: The 1.8mm outer diameter enables flexible routing through cable trays and conduit systems. FC/APC connectors provide superior return loss characteristics, while ST/UPC connectivity ensures broad compatibility. Straight-through polarity design simplifies installation and reduces configuration errors. Customization and Availability: Available in custom lengths beyond the standard 85-meter specification, this cable adapts to unique installation requirements. Multiple domestic warehouses (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid fulfillment with free standard shipping on orders exceeding $99. Applications: Ideal for telecommunications networks, data center interconnects, laboratory testing environments, and enterprise fiber optic installations where signal integrity and regulatory compliance are paramount. The 90-day limited warranty provides additional confidence in long-term deployment reliability.
