The JBX89181 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity engineered for demanding network environments. This 1-meter cable connects SC/UPC to ST/UPC connectors in a Type A to B crossover configuration—the most common standard for duplex patch cord applications. Technical Excellence: Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable meets stringent telecommunications standards. Independent attenuation testing confirms performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths. The ≤0.35dB insertion loss (0.15dB typical) and ≥20dB return loss ensure minimal signal degradation, critical for long-distance and high-bandwidth applications. Robust Construction: The 1.8mm outside diameter cable features riser-rated (OFNR) PVC jacketing, suitable for installation in building risers and pathways. RoHS/ELV compliance (EU Directive 2002/95/EC) meets environmental regulations. The purple sheathing provides superior visibility for network organization and reduces configuration errors. Practical Applications: Ideal for telecommunications infrastructure, data center interconnects, campus networks, and long-haul transmission systems. The duplex configuration enables bidirectional communication in a single convenient cable. Warranty & Support: 90-day limited warranty provides confidence in reliability. Custom lengths available for specialized installations. Free standard shipping on orders exceeding $99, with convenient fulfillment from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC). Compliance & Standards: TAA-compliant for government and federal procurement. Tested to ANSI/TIA/EIA-455-171-A-2001 standards ensuring interoperability and performance consistency.
