The JBX88114 is a premium 65-meter SC/ST duplex singlemode fiber patch cable designed for professional-grade network installations where reliability and performance are non-negotiable. This cable represents the ideal solution for data centers, telecommunications facilities, and enterprise networks requiring robust optical connectivity over extended distances. **Technical Excellence:** Constructed with a 9/125 micron singlemode fiber core and G.657.A1 glass fiber, this cable delivers superior signal transmission characteristics. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across your network infrastructure. Attenuation performance is optimized at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, supporting diverse optical networking applications. **Compliance & Certifications:** TAA-compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets stringent government and environmental standards. OFNR (Optical Fiber Non-conductive Riser) rating ensures safe installation in plenum and riser spaces, while ANSI/TIA/EIA-455-171-A-2001 certification guarantees attenuation testing accuracy. **Design Features:** The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity—the most common duplex patch cord standard. The bright red 1.8mm diameter jacket provides excellent durability and visibility in crowded equipment racks. Two duplex fiber strands enable full-duplex communication for simultaneous bidirectional data transmission. **Practical Advantages:** Custom lengths are available for applications requiring non-standard configurations. This cable ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery, and qualifies for free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for your network investment. **Ideal Applications:** Perfect for backbone connections, inter-building links, equipment interconnects, and any scenario requiring singlemode fiber's superior distance and bandwidth capabilities.
