The JBX42303 SC/APC to FC/UPC duplex singlemode fiber patch cable is engineered for professionals requiring reliable, high-performance fiber optic connectivity. This 2-meter cable is specifically designed to bridge SC/APC and FC/UPC connectors commonly found in telecommunications equipment, network infrastructure, and data center environments. **Technical Specifications:** Constructed with 9/125 singlemode fiber core meeting G.657.A1 standards, this cable delivers exceptional performance across critical wavelengths. Attenuation specifications of 1310 nm: 0.25 dB/km and 1550 nm: 0.35 dB/km ensure minimal signal loss over extended distances. Insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB provide superior optical quality for demanding applications. **Build Quality & Safety:** The yellow OFNR (Optical Fiber Non-conductive Riser) jacketing provides both visibility and compliance with building code requirements. The 1.8mm outer diameter enables efficient cable management without compromising durability. All materials meet RoHS/ELV directives, supporting sustainable procurement initiatives. **Connectivity Features:** SC/APC (angled) to FC/UPC (straight) connectors facilitate Type A to B crossover connectivity, the industry standard for duplex patch cord applications. This configuration ensures compatibility with most network equipment without requiring additional adapters. **Compliance & Warranty:** TAA (Trade Agreements Act) compliance makes this cable suitable for government and institutional procurement. Manufactured to ANSI/TIA/EIA-455-171-A-2001 standards and backed by a 90-day limited warranty. Available from multiple US distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders exceeding $99. **Applications:** Ideal for network upgrades, telecommunications infrastructure, data center interconnections, and laboratory fiber optic testing. Custom lengths available to accommodate specific deployment requirements, providing flexibility for complex installations. **Quality Assurance:** Each cable undergoes rigorous attenuation testing to ensure consistent performance. The combination of precision manufacturing and quality control results in a reliable product that meets professional networking standards.
