The JBX00006 SC/UPC OS2 singlemode fiber pigtail represents the ideal choice for telecommunications professionals and network installers seeking reliable, high-performance fiber optic connectivity. This 1-meter cable combines industry-leading specifications with practical design features to support demanding network applications. **Technical Excellence:** Constructed with a 9/125µm singlemode core and advanced G.657.A1 glass fiber, this pigtail delivers exceptional performance across standard telecommunications wavelengths. The insertion loss specification of ≤0.35dB (with 0.15dB typical performance) ensures minimal signal degradation, while the return loss rating of ≥20dB provides superior signal reflection control. These performance metrics have been verified through rigorous testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Design and Construction:** The 0.9mm tight-buffered jacket offers robust protection against environmental factors and handling stress. The distinctive yellow color provides clear visual identification in cable runs and patch panels, reducing installation errors and simplifying network maintenance. As an unterminated pigtail, it provides maximum flexibility for custom field termination applications, allowing integration into existing network infrastructure. **Compliance and Standards:** Full RoHS/ELV compliance ensures this product meets stringent environmental and safety standards required in professional installations. TAA compliance broadens its applicability across government and enterprise sectors. The 90-day limited warranty provides peace of mind for critical network deployments. **Applications:** Ideal for telecommunications networks, data center installations, LAN/WAN implementations, fiber-to-the-desktop (FTTD) systems, and any single-mode network requiring reliable signal transmission. The SC/UPC connector format offers broad compatibility with standard network equipment. **Availability:** Custom lengths available for specialized installation requirements. Free standard shipping on orders exceeding $99, with expedited options for time-sensitive projects. Ships from multiple US locations ensuring rapid delivery.
