The JBX42388 SC/APC to ST/UPC duplex fiber patch cable represents the ideal solution for professional fiber optic network installations requiring extended cable runs. At 85 meters, this cable eliminates the need for multiple shorter segments, reducing connection points and potential signal loss while simplifying installation logistics. **Superior Signal Performance:** Built with 9/125 singlemode fiber and G.657.A1 glass fiber, this cable meets the most stringent telecommunications standards. The SC/APC (Angled Physical Contact) connector end minimizes back-reflection, while the ST/UPC end ensures compatibility with legacy systems. Tested attenuation specifications confirm ≤0.35dB insertion loss at standard wavelengths, ensuring reliable long-distance data transmission. **Professional-Grade Construction:** The 1.8mm outside diameter provides flexibility for routing through tight spaces, while the OFNR (Optical Fiber Non-Conductive Riser) rating ensures compliance with building codes for vertical installations. The durable plastic jacketing resists environmental stressors, and the distinctive yellow color simplifies cable identification in complex network installations. **Compliance & Reliability:** Fully TAA compliant and RoHS/ELV certified, this cable meets federal procurement and environmental standards. Each unit undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. The Type A to B crossover polarity configuration is optimized for duplex transmission applications. **Flexible Deployment Options:** Available for immediate shipment from multiple US locations with free standard shipping on orders over $99. Custom lengths are available for unique installations. The 90-day limited warranty provides peace of mind for critical network deployments. **Ideal Applications:** Data centers, telecommunications facilities, enterprise networks, campus backbone connections, and any installation requiring 85-meter single-mode fiber runs. Perfect for organizations upgrading legacy ST/UPC systems while maintaining SC/APC standardization.
