The JBX42269 90-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for enterprise-class fiber optic network installations. Engineered to professional standards, this cable bridges connections between different connector types—a common requirement in heterogeneous network environments where legacy equipment coexists with modern infrastructure. **Technical Excellence** Constructed with G.657.A1 bend-insensitive glass fiber, this singlemode cable delivers superior performance with minimal signal loss. The 9/125 micron core size is specifically engineered for singlemode operation, ensuring optimal light transmission across the 90-meter span. Laboratory testing confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB, meeting ANSI/TIA/EIA-455-171-A standards. **Installation Features** The bright yellow OFNR riser-rated jacketing provides both visibility and building code compliance. The 1.8mm outer diameter ensures compatibility with standard cable management systems, while the duplex configuration enables simultaneous bidirectional communication. The Type A to B crossover polarity ensures proper signal routing in standard duplex patch cord applications. **Compliance & Reliability** TAA-compliant manufacturing makes this cable eligible for government and institutional procurement. RoHS/ELV certification confirms environmental responsibility. Available from multiple U.S. fulfillment centers (California, Texas, South Carolina) for rapid delivery, with free standard shipping on orders exceeding $99. **Use Cases** Ideal for data centers, telecommunications facilities, educational institutions, and enterprise networks requiring long-distance fiber connections between dissimilar connector types. The 90-meter length accommodates multi-floor buildings and distributed network architectures. **Customization Options** While this product is specified at 90 meters, custom lengths are available to match your exact installation requirements. Contact sales for custom configurations. **Warranty & Support** Backed by a 90-day limited warranty and compliant with international standards, this cable provides reliable performance for critical network infrastructure.
