The JBX42984 15m LC/UPC singlemode fiber patch cable represents professional-grade connectivity for demanding network applications. Engineered with precision-matched LC/UPC connectors on both ends, this simplex cable configuration delivers single-strand transmission ideal for unidirectional signal paths in modern telecommunications infrastructure. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass specification, this cable achieves industry-leading performance metrics. Insertion loss measures ≤0.35dB at 1310nm (0.25 dB/km) with typical performance of 0.15dB, while return loss exceeds 20dB. These specifications ensure minimal signal degradation over the 15-meter span, critical for maintaining data integrity in high-speed networks. **Compliance & Safety:** Full TAA compliance makes this cable eligible for U.S. government procurement. RoHS/ELV certification ensures environmental responsibility, meeting EU Directive 2002/95/EC requirements. OFNR riser rating allows safe installation throughout building structures without conduit, reducing installation complexity and costs. **Practical Design:** The distinctive yellow jacket facilitates rapid identification and troubleshooting in crowded cable trays and patch panels. The 1.8mm outside diameter maintains compatibility with standard LC connector housings and fiber management systems. Straight-through polarity ensures predictable signal flow without confusion. **Custom Solutions:** While this product ships in 15m length, custom lengths are available for specialized applications. Multiple manufacturing options (Taiwan, US, China) ensure supply chain resilience and competitive pricing. **Ideal Applications:** Perfect for data center interconnects, telecom backhaul, fiber-to-the-desktop deployments, and laboratory testing. Particularly suited for government agencies, enterprises, and service providers requiring TAA-compliant components. The 90-day limited warranty provides peace of mind, backed by ANSI/TIA/EIA-455-171-A testing standards. Ships free on orders exceeding $99 from strategically located U.S. facilities.
