The JBX85079 25m LC/ST Duplex Singlemode Fiber Patch Cable represents the gold standard in fiber optic connectivity solutions. Designed for professionals who demand reliability, performance, and longevity, this cable delivers consistent signal transmission across extended distances in demanding network environments. **Technical Excellence:** Built with a 9/125 micron singlemode core and G.657.A1 glass fiber, this cable meets stringent industry standards including ANSI/TIA/EIA-455-171-A-2001 attenuation specifications. With insertion loss of just ≤0.35dB (0.15dB typical) and return loss ≥20dB, the JBX85079 ensures minimal signal degradation. Performance is verified at both 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km) wavelengths, making it suitable for diverse telecommunications protocols. **Design & Durability:** The distinctive yellow OFNR-rated jacket (1.8mm outer diameter) provides exceptional durability while enabling quick visual identification in complex installations. This riser-rated construction ensures compliance with building codes and safety regulations, making it ideal for vertical cable runs in multi-story facilities. **Connector Configuration:** Featuring LC/UPC to ST/UPC connectors with Type A to B crossover polarity—the industry standard for duplex patch cords—this cable integrates seamlessly into existing telecommunications infrastructure. Both connectors provide UPC (Ultra Physical Contact) polish for optimal performance. **Applications:** Ideal for: • Data center backbone connectivity • Telecommunications network infrastructure • Enterprise campus networks • Long-distance signal transmission • High-speed data transmission requiring minimal latency **Compliance & Support:** RoHS and ELV compliant, the JBX85079 meets strict environmental and safety standards. Each cable ships from strategically located U.S. facilities (Danville CA, Fort Worth TX, or Beaufort SC) ensuring rapid delivery. Enjoy free standard shipping on orders exceeding $99 and comprehensive 90-day limited warranty protection. **Custom Options Available:** Require a different length?
