The JBX85084 50m LC/ST duplex singlemode fiber patch cable represents a professional-grade solution for mission-critical fiber optic applications. Constructed with precision engineering, this cable features a 9/125 singlemode core with G.657.A1 optical fiber, delivering industry-leading performance for long-distance signal transmission. Key Technical Specifications: The cable achieves exceptional low insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, ensuring minimal signal degradation. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet ANSI/TIA/EIA-455-171-A-2001 testing standards, making it suitable for both short-reach and long-haul applications. Design & Construction: The bright yellow OFNR-rated (Optical Fiber Non-conductive Riser) jacket provides excellent visibility for quick identification during complex installations while maintaining fire safety compliance in building environments. The compact 1.8mm outer diameter allows for flexible routing through tight conduits and cable trays. Duplex configuration with Type A to B crossover polarity enables seamless integration with most standard network equipment. Connector Quality: LC/UPC to ST/UPC connectors ensure secure, low-loss connections with minimal back-reflection. These industry-standard connectors are compatible with telecommunications, data center, and enterprise network infrastructure. Compliance & Reliability: Fully RoHS and EU directive 2002/95/EC compliant, this cable meets stringent environmental and safety standards. The 90-day limited warranty provides peace of mind for critical network deployments. Custom lengths are available to accommodate specific installation requirements. Ideal Applications: Perfect for telecommunications networks, data center interconnects, LAN/WAN implementations, and any application requiring reliable singlemode fiber connectivity. The 50-meter length suits intermediate-distance backbone and horizontal cabling runs. Shipping & Support: Enjoy free standard shipping on orders exceeding $99, with convenient fulfillment from multiple US locations (Danville, CA; Fort Worth, TX; Beaufort, SC). Custom availability options allow for tailored solutions to meet unique network requirements.
