The JBX42070 8-meter LC/APC to SC/UPC duplex singlemode fiber patch cable represents a critical component for modern high-speed fiber optic networks. Designed for data centers, telecommunications facilities, and enterprise network infrastructure, this cable facilitates reliable point-to-point fiber signal transmission with minimal signal loss. **Technical Specifications:** This duplex patch cable features a 9/125 singlemode fiber core with G.657.A1 specification, optimized for long-distance signal transmission. The cable achieves exceptional attenuation performance: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, with insertion loss ≤0.35dB (0.15dB typical) and return loss ≥20dB. Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, it ensures consistent, predictable performance. **Connector Configuration:** The LC/APC to SC/UPC configuration provides Type A to B crossover polarity, the most common standard for duplex patch cords. This design enables straightforward integration into existing network infrastructure without requiring additional adapters or workarounds. **Installation & Durability:** The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance suitable for in-building vertical runs while offering easy cable identification. The 1.8mm outer diameter ensures compatibility with standard conduit systems and cable management solutions. RoHS and ELV compliant, this cable meets environmental regulations and government procurement standards including TAA compliance. **Flexibility & Customization:** While this product is offered in 8-meter configuration, custom lengths are available to meet specific installation requirements. Ships from Danville CA, Fort Worth TX, and Beaufort SC locations with free standard shipping on orders exceeding $99. **Applications:** Ideal for telecommunications, data center interconnects, enterprise LANs, CATV systems, and any fiber optic network requiring low-loss, reliable signal transmission. The 90-day limited warranty provides assurance of quality and performance.
