The JBX00026 1m LC/UPC Simplex OS2 Singlemode Fiber Pigtail represents a precision optical component engineered for telecommunications, data center, and enterprise network applications requiring high-performance fiber connectivity. This professionally-manufactured pigtail combines exceptional optical characteristics with robust physical construction. **Key Technical Features:** This simplex fiber pigtail utilizes G.657.A1 singlemode glass fiber with a 9/125 micron core configuration, delivering reliable single-mode transmission across both 1310nm and 1550nm wavelengths. The 0.9mm tight-buffered yellow jacket provides excellent protection while maintaining flexibility for installation in confined spaces. Attenuation performance is rigorously tested—0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm—meeting ANSI/TIA/EIA-455-171-A-2001 standards. Insertion loss specifications of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation. **Industry Compliance & Reliability:** Fully RoHS/ELV compliant (EU Directive 2002/95/EC) and TAA certified, this component meets rigorous environmental and trade compliance requirements. The LC/UPC connector configuration provides superior optical return loss performance compared to APC alternatives, making it ideal for standard telecommunications applications. A 90-day limited warranty protects your investment. **Practical Applications:** Ideal for DWDM systems, telecommunications infrastructure, laboratory testing, equipment interconnection, and enterprise data center deployments. The yellow jacket aids in circuit identification within large-scale installations. Custom lengths are available for specialized applications. **Value Proposition:** Offered with free standard shipping on orders exceeding $99, with convenient fulfillment from multiple U.S. locations (Danville CA, Fort Worth TX, or Beaufort SC). Ships in compact 10x10x10 packaging suitable for inventory management.
