The JBX42628 85-meter FC/APC to ST/UPC duplex singlemode fiber patch cable represents enterprise-level connectivity solutions for mission-critical network infrastructure. This professional-grade optical cable is specifically engineered to transmit fiber signals with exceptional clarity and reliability in telecommunications and data center environments. Technical Excellence: Built with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers superior optical performance. The dual-strand duplex configuration enables simultaneous bidirectional signal transmission. With insertion loss specifications of ≤0.35dB at both 1310nm and 1550nm wavelengths, and return loss exceeding 20dB, this cable exceeds ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing. Physical Specifications: The cable features a compact 1.8mm outside diameter jacketing with OFNR (Optical Fiber Non-conductive Riser) rating, making it suitable for in-building installation. The distinctive yellow jacket provides instant visual identification for FC/APC connections, ensuring proper installation and maintenance. Compliance & Reliability: TAA compliant and manufactured to meet EU directive 2002/95/EC (RoHS), this cable is suitable for government and enterprise procurement. The Type A to B crossover polarity configuration (most common for duplex patch cords) ensures seamless integration with existing network infrastructure. Customization & Availability: Custom lengths are available to meet specific installation requirements. Ships from multiple U.S. locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. Applications: Ideal for telecommunications networks, data centers, service provider infrastructure, and enterprise-grade network installations requiring reliable, low-loss signal transmission over extended distances.
