The JBX00042 ST/UPC OS2 Singlemode Fiber Pigtail represents a premium solution for professionals requiring dependable fiber optic connectivity. This 1-meter simplex fiber pigtail is engineered to deliver exceptional performance in mission-critical telecommunications and data transmission applications. **Technical Excellence** Constructed with 9/125µm singlemode fiber meeting G.657.A1 standards, this pigtail is optimized for long-distance, high-bandwidth signal transmission. The fiber undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance at standard telecommunications wavelengths: 1310nm (0.25dB/km) and 1550nm (0.35dB/km). With insertion loss specifications of ≤0.35dB and return loss ≥20dB, this pigtail minimizes signal degradation and reflection. **Design & Durability** The 0.9mm tight-buffered yellow jacket provides excellent durability and convenient color identification for network management. The simplex (single-strand) configuration is ideal for unidirectional transmission applications or when paired with complementary components. The straight-through polarity ensures seamless connectivity without complications. **Versatile Applications** Perfect for data centers, telecommunications networks, CATV systems, and enterprise fiber infrastructure. The pigtail's compact design and lightweight construction (0.2" height, 5" dimensions) facilitate easy installation in crowded rack environments. **Compliance & Warranty** RoHS and ELV compliant per EU Directive 2002/95/EC, ensuring environmental responsibility. TAA compliant for government and institutional procurement. Includes 90-day limited warranty for peace of mind. **Customization Available** While this product ships in 1m lengths, custom lengths are available to meet specific installation requirements.
