The JBX42026 75m LC/APC to LC/UPC duplex single-mode fiber patch cable represents a premium solution for professional fiber optic network installations requiring reliability, performance, and regulatory compliance. **Technical Excellence** This cable utilizes 9/125 single-mode fiber with G.657.A1 glass composition, specifically designed for long-distance, high-bandwidth signal transmission. The APC (Angled Physical Contact) to UPC (Ultra Physical Contact) connector configuration minimizes back-reflections and signal degradation, making it ideal for sensitive telecommunications and data center applications. **Superior Performance Specifications** With insertion loss ratings of just ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB, this cable meets rigorous telecommunications standards. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 protocols, ensuring consistent performance at both 1310nm and 1550nm wavelengths—the primary fiber optic communication bands. **Durability and Compliance** The yellow OFNR (Riser Rated) jacket provides flame-resistance and durability in building installations while maintaining a slim 1.8mm outside diameter for space-efficient routing. The cable is fully RoHS and ELV compliant, meeting EU directive 2002/95/EC requirements. TAA compliance ensures suitability for government and regulated sector deployments. **Practical Installation** Manufactured with Type A to B crossover polarity—the industry standard for duplex patch cords—this cable integrates seamlessly with existing network infrastructure. At 75 meters, it's ideal for campus backbone connections, inter-building links, and long-run data center applications. Custom lengths are available for specialized requirements. **Shipping and Support** Shipped from multiple U.S. locations (California, Texas, and South Carolina) for rapid delivery, this cable qualifies for free standard shipping on orders exceeding $99. All products include a 90-day limited warranty, backed by professional technical support. **Applications** Perfect for telecommunications facilities, data centers, broadcast facilities, campus networks, and any installation requiring long-distance, single-mode fiber connectivity with rigorous performance standards.
