The JBX42244 2.5-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents the gold standard in professional fiber-optic connectivity. Engineered for telecommunications networks, data centers, and enterprise infrastructure, this cable combines superior optical performance with practical durability. **Technical Excellence** Features a 9/125 micrometer singlemode core constructed from premium G.657.A1 glass fiber, ensuring low-loss signal transmission across both 1310nm and 1550nm wavelengths. Typical insertion loss measures just 0.15dB with maximum 0.35dB, while return loss exceeds 20dB—exceeding industry expectations. Every cable undergoes individual attenuation testing per ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance. **Compliance & Standards** TAA compliant for government and institutional procurement, meeting federal Buy American requirements. RoHS/ELV compliant with EU directive 2002/95/EC compliance. The riser-rated (OFNR) yellow jacket provides flame resistance while clearly identifying the cable type in busy installations. **Practical Design** The Type A to B crossover polarity configuration suits duplex patch cord applications perfectly. At just 1.8mm outside diameter, the cable fits comfortably in cable trays and conduit without excessive bulk. The bright yellow jacket enhances visibility and organization in equipment racks. **Customization & Availability** While this 2.5m length addresses common deployment scenarios, custom lengths are available to match your specific infrastructure requirements. Manufactured with quality control across Taiwan, US, and China facilities, orders typically ship from Danville, CA, Fort Worth, TX, or Beaufort, SC. **Value & Support** Enjoy free standard shipping on orders exceeding $99, with a 90-day limited warranty providing peace of mind. Whether upgrading existing networks or deploying new fiber infrastructure, this TAA-compliant duplex patch cable delivers professional-grade reliability at competitive pricing.
