The JBX92193 SC/ST singlemode fiber patch cable represents an industry-standard solution for professional fiber optic network installations. Measuring 12 meters in length with duplex configuration, this cable accommodates bidirectional communication in telecommunications infrastructure, data centers, and enterprise networks. Technical Excellence: Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, the cable delivers superior performance characteristics. Attenuation measurements of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss across operating wavelengths. Insertion loss testing demonstrates ≤0.35dB typical performance of 0.15dB, while return loss exceeds 20dB, exceeding industry standards for long-distance transmission. Connector Configuration: The SC/UPC to ST/UPC connectors provide secure, reliable connections with low back-reflection characteristics. The Type A to B crossover polarity configuration represents the most common duplex patch cord standard, simplifying integration into existing fiber networks without requiring adapter cables. Compliance & Safety: TAA compliance makes this cable eligible for government and public sector contracts. RoHS and ELV directive adherence ensures environmental responsibility. OFNR riser rating permits installation in building plenums and vertical runs without conduit protection, reducing installation costs and complexity. Application Versatility: Ideal for connecting telecommunications equipment, network switches, optical distribution frames, and data center infrastructure. The 1.8mm outer diameter accommodates standard cable pathways and raceways. Whether upgrading existing installations or deploying new networks, this patch cable delivers reliable, standards-compliant performance. Warranty & Support: Backed by a 90-day limited warranty with convenient shipping from multiple US locations (Danville CA, Fort Worth TX, or Beaufort SC). Custom length options available for specialized requirements. Professional-grade construction ensures years of dependable network connectivity.
