The JBX00061 0.5m FC/UPC Simplex OS2 Singlemode Fiber Pigtail represents a premium solution for fiber optic connectivity in professional networking environments. Engineered to exacting standards, this pigtail combines reliability with performance, making it an ideal choice for telecommunications operators, data center engineers, and network integrators. **Technical Excellence:** This singlemode fiber pigtail features a precisely engineered 9/125 micron core with G.657.A1 glass fiber construction, ensuring optimal light propagation and signal fidelity. The ≤0.35dB insertion loss and ≥20dB return loss specifications exceed industry expectations, delivering minimal signal degradation over the 0.5-meter length. Attenuation testing has been conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance at both 1310nm and 1550nm wavelengths. **Design and Durability:** The 0.9mm tight-buffered yellow PVC jacket provides excellent protection while offering easy identification in complex cable environments. The vibrant yellow color coding simplifies network documentation and troubleshooting. The FC/UPC connector provides secure, repeatable connections with superior optical performance compared to APC-style connectors. **Compliance and Certification:** Fully compliant with RoHS (EU directive 2002/95/EC) and ELV directives, this pigtail meets environmental and regulatory standards for global deployment. TAA compliance ensures suitability for government and enterprise contracts. **Applications:** Ideal for use in telecommunications infrastructure, DWDM systems, fiber-to-the-home (FTTH) installations, laboratory environments, and data center patch systems. The simplex design suits applications requiring single-direction transmission. **Customization and Support:** While this product is optimized at 0.5 meters, custom lengths are available to meet specific project requirements. Backed by a 90-day limited warranty and shipped from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for faster delivery. Free standard shipping applies to orders exceeding $99.
