The JBX00104 12-Fiber LC/UPC Pigtail represents the pinnacle of fiber optic connectivity solutions for professionals demanding superior performance and reliability. This 3-meter assembly combines factory precision with field flexibility, making it an essential component for modern fiber infrastructure. **Superior Specifications:** Constructed with OS2 singlemode fiber featuring a 9/125 micrometer core/cladding ratio, this pigtail delivers exceptional performance across critical telecommunications wavelengths. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss over extended distances. The insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB meet the stringent requirements of professional installations. **Design Features:** The 0.9mm diameter unjacketed fiber with color-coded identification enables seamless integration into high-density fiber management systems. Each of the 12 individual fibers arrives pre-terminated with LC/UPC connectors (straight-through polarity) on one end, while the opposite end remains unterminated for custom splicing, fusion termination, or mechanical termination as needed. This hybrid approach maximizes installation flexibility while minimizing field preparation requirements. **Application Versatility:** Ideal for data centers, telecommunications facilities, DWDM systems, and enterprise networks, this pigtail excels in applications requiring compact fiber routing, high channel density, and exceptional reliability. The G.657.A1 fiber classification ensures bend-insensitive performance, protecting signal integrity even in tight routing scenarios. **Quality Assurance:** RoHS and ELV compliant with TAA certification, the JBX00104 meets international regulatory standards. Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, each unit includes a 90-day limited warranty. Available in custom lengths for specialized applications, this pigtail accommodates unique installation requirements. **Logistics:** Manufactured in Taiwan, the United States, or China, units ship from Danville, CA; Fort Worth, TX; or Beaufort, SC for expedited delivery. Free standard shipping applies to orders exceeding $99, reducing total installation costs.
