The JBX00041 ST/UPC OS2 Singlemode Fiber Pigtail represents a critical component in modern optical networking infrastructure. At 0.5 meters in length with a distinctive yellow 0.9mm jacket, this simplex pigtail is engineered to deliver reliable, high-performance signal transmission in professional telecommunications environments. ## Technical Specifications This singlemode pigtail utilizes a 9/125 micron core with premium G.657.A1 glass fiber construction, meeting industry standards for single-mode optical transmission. The fiber is optimized for dual-wavelength operation at both 1310nm and 1550nm wavelengths, with attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The measured insertion loss is exceptionally low at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB, ensuring minimal signal degradation and reflection issues. ## Design and Construction Featuring ST/UPC connectors with straight-through polarity, this pigtail includes one unterminated end for flexible splicing applications. The 900µm tight-buffered jacket provides mechanical protection while maintaining the compact diameter essential for dense optical installations. The yellow coloring aids in quick visual identification during installation and maintenance operations. ## Compliance and Quality Assurance Manufactured to rigorous international standards, this component is fully RoHS compliant under EU directive 2002/95/EC and carries TAA (Trade Agreements Act) certification, making it suitable for government and institutional procurement. All attenuation measurements conform to ANSI/TIA/EIA-455-171-A standards, ensuring consistency and reliability across installations. ## Applications and Use Cases Ideal for data center interconnections, telecommunications backbones, enterprise network upgrades, and equipment patch panel installations. Suitable for both new installations and equipment upgrades where OS2 singlemode performance is required. The compact 0.5-meter length makes this particularly valuable for equipment-to-panel connections and short-distance backbone links. ## Customization and Support Custom lengths are available upon request to accommodate specific installation requirements. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty, providing confidence in long-term performance and reliability.
