The JBX42192 10m LC/APC to FC/UPC Duplex Fiber Patch Cable represents the pinnacle of singlemode fiber connectivity technology. Designed for professionals who demand uncompromising performance, this cable combines precision engineering with practical reliability for mission-critical network applications. **Technical Excellence**: Built with G.657.A1 glass fiber and a 9/125 singlemode core, this cable delivers superior signal integrity across standard telecommunications wavelengths. The LC/APC (Angled Physical Contact) to FC/UPC (Ultra Physical Contact) configuration ensures Type A to B crossover polarity, the industry standard for duplex patch cord applications. Insertion loss testing confirms ≤0.35dB performance (0.15dB typical) at both 1310nm and 1550nm wavelengths, ensuring minimal signal degradation over your network backbone. **Compliance & Reliability**: TAA compliance makes this cable ideal for government, enterprise, and educational institutions with procurement requirements. RoHS/ELV directive compliance guarantees environmentally responsible manufacturing. The OFNR riser-rated jacketing permits installation in building plenums and between floors without conduit, simplifying deployment while maintaining safety standards. Return loss of ≥20dB provides excellent signal reflection control. **Practical Design**: The distinctive yellow jacket enables quick identification in data centers with multiple cable types, reducing installation errors and maintenance time. The compact 1.8mm outside diameter fits snugly in cable trays and conduits without excessive bulk. Duplex configuration transmits signals bidirectionally through a single cable, reducing physical footprint and installation complexity. **Versatile Applications**: Perfect for data center interconnects, telecom equipment upgrades, enterprise LAN extensions, and laboratory environments. The 10-meter length accommodates typical rack-to-switch distances and cross-cabinet runs. Custom lengths are available for specialized installations. **Value & Support**: Manufactured in Taiwan, the US, or China with domestic shipping from Danville CA, Fort Worth TX, or Beaufort SC, ensuring rapid delivery. Free standard shipping on orders over $99 reduces total cost of ownership. The 90-day limited warranty provides peace of mind for your investment. Whether upgrading existing infrastructure or building new networks, the JBX42192 delivers professional-grade performance at exceptional value.
