The JBX42250 8-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for demanding network infrastructure projects. Designed for organizations requiring maximum signal fidelity and regulatory compliance, this cable combines precision engineering with practical durability. **Technical Excellence** Built with 9/125 singlemode core fibers and G.657.A1 glass composition, this patch cable delivers outstanding optical performance. The LC/APC connector offers superior return loss (≥20dB), while the ST/UPC termination ensures reliable mechanical connections. Insertion loss measures ≤0.35dB with typical performance at just 0.15dB, significantly below industry standards. Performance specifications conform to ANSI/TIA/EIA-455-171-A-2001 testing protocols. **Reliability & Durability** The 1.8mm outer diameter yellow jacket features riser-rated (OFNR) construction, providing flame resistance and excellent crush protection. The Type A to B crossover polarity configuration represents the industry-standard duplex arrangement, ensuring compatibility with most network equipment. Comprehensive RoHS/ELV compliance and TAA certification make this cable suitable for federal procurement and regulated environments. **Practical Benefits** The vibrant yellow jacket simplifies cable identification in high-density installations, reducing troubleshooting time and installation errors. At 8 meters, this length accommodates typical equipment-to-rack or building-to-building runs while minimizing signal degradation. Custom length options are available for unique installation requirements. **Perfect For** Telecommunications facilities, enterprise data centers, government installations, carrier networks, and any application requiring certified, compliant singlemode connectivity. **Shipping & Support** Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Every cable includes a 90-day limited warranty. Manufactured in Taiwan, US, or China with consistent quality standards across all production locations.
