The JBX42612 10-meter FC/APC to ST/UPC duplex singlemode fiber patch cable represents a professional-grade solution for telecommunications and network infrastructure applications. Built with precision engineering and quality materials, this optical cable delivers exceptional performance in demanding environments. Technical Excellence: This patch cable features a 9/125 singlemode fiber core constructed from premium G.657.A1 glass fiber, specifically designed for long-distance, high-bandwidth signal transmission. The cable achieves exceptional attenuation characteristics of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, ensuring minimal signal loss over extended distances. With insertion loss ratings of ≤0.35dB (0.15dB typical) and return loss ≥20dB, the cable exceeds ANSI/TIA/EIA-455-171-A-2001 standards, making it suitable for mission-critical applications. Connector Compatibility: The FC/APC (Angled Physical Contact) to ST/UPC (Ultra Physical Contact) configuration provides Type A to B crossover polarity, the industry standard for duplex patch cord applications. This connector combination ensures reliable connections across diverse networking equipment from multiple manufacturers. Safety and Compliance: Riser-rated (OFNR) jacketing certifies this cable for safe indoor installation without conduit, reducing installation complexity and costs. The cable achieves RoHS/ELV compliance and EU directive 2002/95/EC certification, meeting environmental and safety requirements worldwide. TAA compliance ensures this product meets government procurement standards. Physical Specifications: The 1.8mm outside diameter allows seamless integration into standard cable management systems and patch panel installations. The vibrant yellow jacket facilitates quick identification and organization in busy network environments. The duplex configuration (two fiber strands) enables simultaneous bidirectional communication. Applications and Use Cases: Ideal for data centers, telecommunications facilities, enterprise networks, and fiber optic backbone installations. Commonly used in DWDM systems, long-haul telecommunications, and high-speed internet infrastructure. The 10-meter length accommodates standard equipment spacing in server racks and network closets. Warranty and Support: Backed by a 90-day limited warranty ensuring product reliability. Custom lengths available for specialized installations. Free standard shipping on orders exceeding $99, with strategic warehouse locations in Danville CA, Fort Worth TX, and Beaufort SC for rapid delivery nationwide.
