The JBX42446 75-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents the industry standard for professional-grade fiber optic connectivity. This cable combines precision engineering with reliable performance, making it an essential component for telecommunications infrastructure, data centers, and enterprise networks. Technical Excellence: Built with 9/125 singlemode fiber cores and G.657.A1 glass fiber specifications, this duplex cable supports long-distance signal transmission with minimal attenuation. The insertion loss specification of ≤0.35dB (with typical performance of 0.15dB) ensures clean, strong signal delivery, while the return loss of ≥20dB guarantees signal integrity across both the 1310nm and 1550nm wavelengths commonly used in optical networks. Compliance & Standards: This cable meets rigorous industry requirements including ANSI/TIA/EIA-455-171-A standards and features RoHS/ELV compliance for environmentally responsible procurement. TAA compliance makes it ideal for government and regulated organization purchases. The OFNR (Optical Fiber Nonconvoluted Riser) rating ensures safe installation in vertical runs and plenum spaces. Design & Durability: The bright yellow outer jacket (1.8mm diameter) provides easy identification in complex network installations while offering robust protection. The Type A to B crossover polarity configuration is the most common duplex arrangement, eliminating confusion during deployment. Applications: Perfect for backbone connectivity, cross-connects, and patch panel applications in data centers, telecom facilities, and enterprise networks. The 75-meter length accommodates mid-distance runs without excessive slack. Flexibility: Custom lengths are available for specific installation requirements, and competitive pricing includes free standard shipping on orders exceeding $99. With 90-day warranty coverage and rapid shipping from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC), this cable delivers reliable service when you need it most.
