The JBX42566 75-meter ST/APC to FC/UPC duplex fiber patch cable represents a premium solution for professional network installations demanding reliable, long-distance fiber optic connectivity. This cable is engineered for telecommunications providers, data centers, and enterprise networks requiring exceptional performance and compliance certification. **Technical Excellence** Built with singlemode 9/125 core fiber and G.657.A1 glass composition, this cable delivers industry-leading performance specifications. With insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB, it minimizes signal degradation across the full 75-meter length. Attenuation is rated at 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, meeting ANSI/TIA/EIA standards for optical fiber testing. **Compliance and Safety** This patch cable is TAA (Trade Agreements Act) compliant, making it ideal for government and institutional procurement. Full RoHS and EU Directive 2002/95/EC compliance ensures environmentally responsible manufacturing. The 1.8mm diameter with OFNR (Optical Fiber Non-Conductive Riser) rated yellow jacketing provides fire safety certification for building installations while maintaining excellent visibility for installation and maintenance. **Practical Applications** The Type A to B crossover polarity configuration suits standard duplex patch cord requirements. Whether upgrading legacy systems or building new infrastructure, the 75-meter length accommodates installations spanning multiple floors or equipment rooms. The combination of ST/APC and FC/UPC connectors provides flexibility in mixed-connector environments. **Durability and Support** Manufactured in Taiwan, the United States, or China, this cable benefits from global quality standards. The 90-day limited warranty provides peace of mind for your investment. Custom lengths are available for specific application requirements, and free standard shipping on orders over $99 makes procurement economical. **Installation Notes** Maintain proper bend radius during installation to preserve fiber integrity. Store in a clean, dry environment to prevent connector contamination. The yellow jacketing facilitates quick identification in complex cable installations.
