The JBX89198 SC/ST Duplex Singlemode Fiber Patch Cable represents a premium solution for professional network connectivity requirements. This 35-meter cable is specifically engineered to meet demanding telecommunications and data center specifications while maintaining cost-effectiveness. **Technical Excellence:** Built with 9/125 singlemode fiber featuring G.657.A1 glass composition, this cable delivers exceptional performance across standard optical wavelengths. The measured insertion loss of 0.15dB typical (maximum 0.35dB) ensures minimal signal degradation, while return loss exceeding 20dB prevents unwanted signal reflections. These specifications comply with ANSI/TIA/EIA-455-171-A-2001 attenuation testing standards, guaranteeing reliable performance. **Superior Connector Design:** The SC/UPC to ST/UPC connector configuration with Type A to B crossover polarity represents the most common and reliable duplex patch cord standard. This universal design simplifies network installations and ensures compatibility across diverse infrastructure setups. **Built for Infrastructure:** The OFNR (Optical Fiber Nonconductive Riser) rating allows safe installation in building vertical runs and plenum spaces. The distinctive purple jacket (1.8mm outer diameter) provides immediate visual identification in complex network environments, reducing installation errors and maintenance confusion. **Compliance and Quality:** Fully TAA compliant with RoHS/ELV certification, this cable meets government procurement standards. Available from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC), it ships quickly with free standard shipping on orders exceeding $99. **Flexible Solutions:** While this product features a 35-meter length, custom lengths are available to precisely match your network topology requirements. Whether upgrading legacy equipment or designing new installations, the JBX89198 adapts to your specifications. **Ideal Applications:** Perfect for telecommunications networks, enterprise data centers, fiber-to-the-desktop implementations, and high-performance computing environments. The combination of singlemode technology and duplex fiber ensures future-proof connectivity for bandwidth-intensive applications. With a 90-day limited warranty and consistent performance across temperature ranges, the JBX89198 provides dependable service for mission-critical network infrastructure.
