The JBX00064 3-meter FC/UPC Simplex OS2 Singlemode Fiber Pigtail represents a professional-grade solution for demanding fiber optic network installations. This single-strand fiber cable combines superior optical performance with robust physical construction to deliver reliable signal transmission in mission-critical applications. **Technical Specifications:** Designed with a 9/125µm singlemode core and G.657.A1 bend-insensitive glass fiber, this pigtail meets OS2 standards for long-distance telecommunications. The 0.9mm tight-buffered yellow jacket provides excellent durability and easy identification in complex cable management scenarios. Measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across 1310nm and 1550nm wavelengths, supporting both short-reach and long-reach optical communications. **Key Features:** - FC/UPC connector for secure, low-reflection connections - Straight-through polarity configuration for standard applications - RoHS/ELV compliant for environmental and regulatory requirements - TAA compliant for government procurement programs - Attenuation tested per ANSI/TIA/EIA-455-171-A standards - 90-day limited warranty for customer protection **Applications & Use Cases:** Perfect for telecommunications infrastructure, data center patch panels, CWDM/DWDM systems, and fiber-to-the-premises (FTTP) deployments. The unterminated design allows seamless integration with existing fiber networks, while custom length availability accommodates unique installation requirements. **Advantages Over Alternatives:** Unlike multimode pigtails, OS2 singlemode fiber delivers superior distance capabilities and lower attenuation rates, making it ideal for long-distance telecommunications. The bend-insensitive G.657.A1 specification provides installation flexibility without performance compromise, while the proven FC/UPC connector standard ensures compatibility across enterprise networks. **Compliance & Quality Assurance:** Manufactured in Taiwan, the US, or China with rigorous quality control, this pigtail meets international standards and carries RoHS certification. Free standard shipping on orders over $99 makes bulk procurement economical for network installations and system integrations. Whether you're upgrading legacy systems or building new fiber infrastructure, the JBX00064 delivers the optical performance, durability, and compliance required for professional telecommunications applications.
