The JBX42132 SC/APC to SC/UPC duplex fiber patch cable represents a professional-grade solution for mission-critical optical networking applications. This 10-meter cable delivers the precision and reliability required by data centers, telecom providers, and enterprise IT infrastructure. **Technical Excellence** Constructed with 9/125 single mode fiber and G.657.A1 glass composition, this duplex cable provides exceptional performance characteristics. The SC/APC-to-SC/UPC configuration enables Type A to B crossover polarity, the industry standard for duplex patch cord applications. Insertion loss measures ≤0.35dB (0.15dB typical) with return loss of ≥20dB, ensuring minimal signal degradation. The cable maintains consistent attenuation of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, meeting ANSI/TIA/EIA standards. **Build Quality and Durability** The 1.8mm outside diameter connector body provides robust construction without excessive bulk. OFNR riser-rated jacketing delivers fire safety compliance for in-building installations while maintaining flexibility for routing through cable trays and conduits. The plastic accessory components and precision connector polishing ensure long-term reliability and consistent performance. **Compliance and Certification** TAA compliance makes this cable eligible for government and federal procurement contracts. RoHS/ELV directive compliance (EU 2002/95/EC) demonstrates environmental responsibility and compatibility with modern manufacturing standards. Manufactured in Taiwan, the United States, or China with rigorous quality control. **Customization and Availability** Beyond the standard 10-meter length, custom lengths are available to match specific network designs and installation requirements. Ships from multiple U.S. locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. **90-Day Warranty Support** Every cable includes a 90-day limited warranty, providing confidence in your network infrastructure investment. **Applications** Ideal for: Data center cross-connects, fiber-to-the-desk implementations, backbone network segments, telecommunications equipment connections, and enterprise campus networks requiring reliable single mode transmission.
