The JBX42069 LC/APC to SC/UPC singlemode fiber patch cable represents professional-quality connectivity for critical network environments. This 7-meter duplex cable combines precision engineering with proven performance standards, making it an excellent choice for organizations requiring reliable fiber optic signal transmission. **Key Features & Specifications:** This singlemode duplex patch cable features a 9/125 core with G.657.A1 glass fiber technology, optimized for long-distance, low-loss signal transmission. The LC/APC (Local Connector/Angled Physical Contact) to SC/UPC (Subscriber Connector/Ultra Physical Contact) configuration provides Type A to B crossover polarity—the industry standard for duplex patch cord applications. With insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable minimizes signal degradation across your network infrastructure. **Professional-Grade Construction:** The cable features a bright yellow OFNR (Optical Fiber Non-conductive Riser)-rated jacket that resists fire and smoke, meeting building code requirements for in-wall installations. The 1.8mm outside diameter provides optimal space efficiency in cable trays and conduit systems. Manufactured to strict ANSI/TIA/EIA-455-171-A-2001 standards, it delivers consistent attenuation performance: 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. **Compliance & Certification:** Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets government procurement requirements and environmental standards. Each cable includes a 90-day limited warranty. **Applications & Use Cases:** Ideal for data center interconnects, telecommunications facilities, enterprise LAN upgrades, and any mission-critical network requiring single-mode fiber connectivity. The duplex configuration simultaneously supports bidirectional communication, making it perfect for long-distance, high-capacity deployments. **Customization & Availability:** While this product is available in the standard 7-meter length, custom lengths are available upon request to match your specific installation requirements. Ships from multiple U.S. locations with free standard shipping on orders over $99. **Technical Excellence:** This cable undergoes rigorous insertion loss testing and maintains performance across operating wavelengths. Its low insertion loss and high return loss specifications minimize signal reflection and interference, ensuring optimal network performance in demanding environments.
