The JBX42373 SC/APC to ST/UPC Duplex Fiber Patch Cable represents a premium solution for fiber optic network connectivity. This 12-meter cable is engineered with professional-grade specifications to meet the demanding requirements of modern telecommunications infrastructure. **Technical Specifications:** Built with a 9/125 micron singlemode core and G.657.A1 glass fiber technology, this duplex patch cable delivers superior signal transmission with minimal loss. The insertion loss rating of ≤0.35dB (0.15dB typical) at standard wavelengths ensures reliable performance across 1310nm and 1550nm wavelengths. The return loss specification of ≥20dB provides excellent signal quality for bidirectional communication. **Compliance & Standards:** Fully TAA compliant for government procurement, RoHS/ELV certified, and tested to ANSI/TIA/EIA-455-171-A standards. The riser-rated (OFNR) yellow jacket provides fire safety certification suitable for plenum and non-plenum installations. **Design Features:** The Type A to B crossover polarity configuration is the industry standard for duplex patch cables, making this cable compatible with most network installations. The compact 1.8mm diameter jacket reduces cable bulk while maintaining durability. The distinctive yellow color improves cable identification and organization in complex network environments. **Applications:** Ideal for data center interconnects, telecommunications systems, network backbone applications, and fiber-to-the-premises (FTTP) installations. Compatible with SC/APC and ST/UPC connector interfaces, this cable bridges different network architecture generations. **Flexibility & Support:** Custom lengths are available to accommodate specific installation requirements.
