The JBX42669 FC/APC to LC/UPC duplex fiber patch cable represents the pinnacle of fiber optic connectivity solutions for telecommunications, data center, and enterprise network applications. This 7-meter cable is meticulously engineered to meet the rigorous demands of modern high-speed data transmission environments. **Technical Excellence:** Constructed with a 9/125 singlemode core and G.657.A1 grade glass fiber, this cable delivers superior optical performance. The FC/APC (angled physical contact) connector on one end provides exceptional return loss protection (≥20dB), while the LC/UPC connector offers broad compatibility with standard telecom infrastructure. Measured insertion loss of ≤0.35dB ensures minimal signal degradation, critical for long-distance and sensitive applications. Performance specifications are validated through rigorous ANSI/TIA/EIA-455-171-A-2001 attenuation testing standards. **Compliance & Safety:** TAA (Trade Agreements Act) compliance makes this cable suitable for government and institutional procurement requirements. Full RoHS/ELV certification under EU directive 2002/95/EC ensures environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser) riser-rated yellow jacket provides fire-safety compliance in multi-story installations while offering superior visibility for cable management. **Practical Features:** The Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring seamless integration with existing infrastructure. The 1.8mm diameter construction allows efficient routing through standard conduit systems. This cable ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery nationwide, with free standard shipping on orders exceeding $99. **Flexibility:** Custom length options are available to accommodate your specific installation requirements, extending beyond the standard 7-meter configuration. Whether upgrading network infrastructure, expanding data center capacity, or establishing critical telecom connections, the JBX42669 delivers reliability, performance, and compliance. Backed by a 90-day limited warranty, this investment in quality fiber optics provides lasting value for your network investment.
