The JBX85094 100m LC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for enterprise-level network infrastructure, data centers, and telecommunications applications requiring reliable high-speed signal transmission over extended distances. **Technical Excellence:** This duplex cable features a precision 9/125 singlemode fiber core constructed with G.657.A1 glass fiber, the industry standard for superior optical performance. The cable delivers exceptional attenuation specifications: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths, with typical insertion loss of just 0.15dB. Return loss exceeding 20dB ensures minimal signal reflection and maximum data integrity. All performance metrics are verified against ANSI/TIA/EIA-455-171-A-2001 standards. **Construction & Safety:** The 1.8mm outside diameter cable is jacketed in OFNR-rated material, meeting safety requirements for riser installations in commercial buildings. The bright yellow outer jacket provides superior visibility for identification and management, reducing installation errors and simplifying maintenance protocols. LC/UPC to ST/UPC connectors feature Type A to B crossover polarity, the most common configuration for duplex patch cord applications. **Compliance & Warranty:** Fully RoHS and ELV compliant, this cable meets EU Directive 2002/95/EC environmental standards. Backed by a 90-day limited warranty, the product ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Flexibility:** Custom lengths are available to meet specific deployment requirements, allowing network engineers to optimize cable management and reduce unnecessary slack in installations. Whether upgrading existing fiber networks or designing new infrastructure, this cable provides the reliability and performance demanded by modern telecommunications applications. **Ideal Applications:** Data center interconnects, campus networks, long-distance backbone connections, and any environment requiring low-loss, high-bandwidth optical transmission.
