The JBX00090 12-Fiber OM4 50/125 Multimode Ribbon Pigtail represents cutting-edge fiber optic connectivity for demanding network environments. This expertly engineered component combines robust performance with practical design features that simplify installation and maintenance in complex fiber infrastructures. **Key Features & Specifications:** This pigtail delivers exceptional optical performance with insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, ensuring minimal signal degradation. The OM4 50/125 multimode fiber operates efficiently at both 850nm and 1300nm wavelengths, with attenuation rated at 3.0 dB/km at 850nm or 1.0 dB/km at 1300nm. The compact 0.9mm unjacketed ribbon design accommodates high-density patching scenarios while the 12-color coding system eliminates polarity confusion during installation. **Design & Construction:** Manufactured from high-quality materials with G.657.A1 glass fiber specifications, this pigtail features straight-through polarity and is available unjacketed for maximum flexibility in tight cable management spaces. The SC/UPC connector on the terminated end provides standard compatibility with most network equipment, while the unterminated 12 fibers allow custom termination to match specific network requirements. **Compliance & Standards:** Fully compliant with TIA-492AAAD and ISO-11801 OM4 standards, this pigtail meets RoHS/ELV directives and EU Directive 2002/95/EC requirements. TAA compliant for government procurement applications. Backed by a 90-day limited warranty and supported by rapid shipping from multiple US locations. **Applications:** Ideal for data centers, telecommunications facilities, university networks, and enterprise campus installations requiring high-density multimode connectivity. Suitable for both new builds and network upgrades where reliability and performance are paramount. **Custom Solutions:** Available in custom lengths to accommodate unique installation requirements.
